Error loading web sites

This article contains information on diagnosing and fixing error messages that display when you try to view websites in Firefox.

Table Of Contents

Connection errors

Error messages that indicate connection problems:
  • Unable to connect
  • Server not found
If you experience one of these errors intermittently, check your Internet connection. If you connect wirelessly, make sure you are connected to the nearest access point and that the signal is strong.
If you experience one of these errors on some or all websites, see the following articles:

Errors loading secure sites

If you experience an error accessing a website over a secure (HTTPS) connection, see the articles below that correspond to the error message you see:

Interrupted or reset connection

The following error can occur if the website you're visiting is experiencing problems:
  • The connection was interrupted
  • The connection was reset
  • The connection has timed out
If you can visit the website in other browsers but not in Firefox:
  1. On the menu bar, click Tools, then select Clear Recent History....
  2. In the Time Range to clear: drop-down, select Everything.
  3. Click the arrow next to Details to display the list of items that can be cleared.
  4. Select both Cookies and Cache.
  5. Click Clear Now.

Proxy errors

Error messages that indicate proxy problems:
  • The proxy server is refusing connections
  • Unable to find the proxy server
This error indicates that Firefox is trying to access the Internet through a proxy server. To check your proxy settings:
  1. On the menu bar, click on the Firefox menu, and select Preferences....
  2. Select the Advanced panel.
  3. Select the Network tab.
  4. In the Connection section, click Settings....
  5. Change your proxy settings:
    • If you don't connect to the Internet through a proxy (or don't know whether you connect through a proxy), select No Proxy.
    • If you connect to the Internet through a proxy, compare Firefox's settings to another browser's (Such as Safari. See Apple's guide to proxy settings).
  6. Close the Connection Settings window.
  7. Close the Preferences window

Malicious website errors

If you receive one of the following errors, Firefox has blocked access to the website you're visiting to protect you from malware or web forgery (phishing).
  • Suspected Attack Site!
  • Suspected Web Forgery!
For more information, see Phishing and Malware Protection (Mozilla.com).

Other error messages

Offline mode

Your operating system indicates to Firefox whether it is connected to the Internet. If it reports that it is not connected, Firefox will go into offline mode. If you are connected:
  • On the menu bar, click File and select Work Offline.

The page isn't redirecting properly

This problem can be caused by problems with cookies:

File not found

If you experience this error when trying to access a local file (with a file:// URL), the path you are trying to access is either incorrect or inaccessible - verify the path.
If you experience this error trying to access a website, see:

Content Encoding Error

The following error messages indicate a content encoding problem:
  • Content Encoding Error
  • The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression
Several problems can result in a content encoding error message. To diagnose and fix:
  1. Check the settings of any Internet security applications you use (including firewalls, anti-virus or anti-spyware programs, and privacy protection programs). You should try to remove any permissions those applications have for Firefox, and then add them again. For program-specific instructions for a number of applications, see Firewalls.
  2. Follow the Standard troubleshooting steps.

This address is restricted

This error occurs when you are attempting to connect to a web server on a port that is reserved for another application.
If the web address (URL) you are trying to visit contains a colon followed by a number (e.g. http://webserver.tld:23), try removing that portion (e.g. http://webserver.tld) or replacing it with :80 (e.g. http://webserver.tld:80)
If specifying a different port does not work, you may have been given an incorrect web address.

Other issues

  • Cannot log in to websites. You may receive an error similar to We were unable to process your login request or An unspecified error has occurred when you attempt to sign into websites with your username and password, or the login may simply fail.

Firefox cache file was infected with a virus

Firefox maintains a cache where it stores temporary files such as web pages and other online media that you have downloaded from the Internet. Your Firefox cache is a folder on your local computer.
When you are performing a scan for viruses, some anti-virus scanners may find a file in your Firefox cache that it believes is a virus.

Note: It is unlikely that you have been infected.

Firefox does not launch some types of files that are downloaded into the cache, which prevents most viruses from propagating to your computer. For a virus to spread to your computer, it must be launched by opening or double-clicking on the file. Unless you have launched the file from inside your Firefox cache, you probably did not get infected with a virus. It is unlikely that Firefox has opened files of a suspicious type.
  • Additionally, anti-virus scanners may incorrectly identify cached files to have a pattern matching a virus. To anti-virus scanners, some files that are otherwise harmless may be mistaken for viruses.
If you are unsure if the file location is in your Firefox cache, you can find the cache location by typing about:cache in the Location bar, and pressing Enter.

Steps

  1. Because the files in the cache are temporary, you can permit the anti-virus scanner to delete the file if it's in your Firefox cache.
  2. You can also clear your Firefox cache at any time. On the menu bar, click on the Firefox menu, and select Preferences....
  3. Select the Advanced panel.
  4. Open the Network tab.
  5. Click on Clear now.
  6. Close the Preferences window

Installing the Flash plugin

Adobe Flash Player is a plugin that allows browsers such as Firefox to display Flash media on web pages. Flash is often used for animations, videos and games.

Installing the Flash plugin manually

  1. Go to Flash Player download page at Adobe.com and download the Flash installer.
  2. From the menu bar, select Firefox and then select the Quit Firefox menu item.
  3. Open the file you downloaded (i.e. install_flash_player_osx_ub.dmg).
  4. In the Finder, open the Adobe Flash Player.pkg to run the installer, then follow the installer's instructions.
After you install Flash, start Firefox again. To confirm that Flash installed, open the Tools and then select Add-ons. If the installation was successful, Shockwave Flash will appear as an active item.

Troubleshooting the Flash plugin

See Managing the Flash plugin for steps to troubleshoot the Flash plugin and keep it up to date.

Firefox will not start

This articles describes what to do if the Firefox window doesn't open when you click the Firefox icon.
  • If Firefox starts but won't load any websites, see Error loading web sites.
  • If you get error messages that indicate a crash, such as "Firefox has encountered a problem and needs to close", "Quality Feedback Agent", or "Mozilla Crash Reporter", see Firefox crashes.

Table Of Contents

Specific error messages

Firefox is already running but is not responding

See Firefox is already running but is not responding for solutions.

Firefox 3 will not start on OSX 10.3.9 or earlier

Mozilla has stopped supporting OSX 10.3.9 and earlier in Firefox 3.0 and higher. None of these operating systems are supported by Apple (and have not been for quite some time) and have multiple vulnerabilities that will remain unpatched. As such, you have the following options:
  1. You can switch to another operating system. This is the most secure option. If you don't want to pay for a new operating system, you can get any of a number of versions of Linux which can run Firefox 3+ and can run on older machines. This ensures you have a completely secure system and access to all the great new features in Firefox 3+.
  2. You can continue to use Firefox 2 which you can get from: our FTP site. Just because the browser will no longer receive security updates doesn't mean it will simply stop working. You will be using unsupported software on an unsupported operating system which poses a significant security risk.

Firefox will not start after installing add-ons

If Firefox previously worked but stopped after you installed extensions or themes, see Troubleshooting extensions and themes.

Firefox previously worked

If Firefox previously worked but suddenly doesn't start, it may be due to some corrupt data in your settings. Uninstalling and reinstalling Firefox would not fix this problem because your settings are not removed on uninstall.
To test to see if this is the problem, use the Profile Manager to create a new profile. If the problem goes away, you can then move your bookmarks and other important settings into the new profile.

Parental controls

This article explains how to block websites or filter website content in Firefox that may be offensive or inappropriate for children.
  • In addition to Firefox extensions, there are many third-party software packages that can filter content through your operating system or at the point where your network connects to the Internet.

Table Of Contents

Parental control add-ons for Firefox

The following third-party extensions can be downloaded and installed into your Firefox browser to help to keep your children safe on the Internet. This Addons.Mozilla.org search for parental control lists several other extensions that may be suitable for your needs.

Glubble for Families

Glubble allows you you create a private family page where you can monitor and support your children’s online activities.

Glubble integrates Ask for Kids, a safe search engine for children. Support for this add-on is provided by the developer at http://glubbleparents.ning.com/forum.

ProCon Latte

  • Available: https://addons.mozilla.org/firefox/addon/1803
  • Cost: Free + option to donate to author
  • Description: Filter out web pages containing explicit content based on text on websites; facility to maintain "good" and "bad" lists of websites
ProCon filters web page content by using a list of inappropriate words and replacing them with asterisks (***). Note that the bad word filter does not block websites containing the words; you must add the website to a Blacklist. ProCon can also block all traffic, making sure that only desired websites (set in the Whitelist) can be accessed. You can manage "white" and "black" lists of sites and pages. ProCon also has password protection in order to keep others from changing the settings. Support and additional documentation for this add-on is provided by the developer at http://procon.mozdev.org/

Table Of Contents



General tab



Accessibility

  • Always use the cursor keys to navigate within pages: When this preference is enabled, Firefox will display a movable cursor in web pages, allowing you to select text with the keyboard. You can toggle this mode by pressing F7.
  • Search for text when I start typing: When this preference is enabled, Firefox will find within the current web page what you type as you type it. While you are finding typed text in the page, the Find Toolbar will automatically display at the bottom of the window to show information about what you've found.
  • Warn me when websites try to redirect or reload the page: When this preference is enabled, Firefox will prevent websites from redirecting you to another page, or automatically reloading.

Browsing

  • Use autoscrolling: Autoscrolling is a useful feature which allows you to scroll the page by clicking the middle mouse button (usually the scroll wheel) and moving the mouse up or down. Some people find this annoying, so autoscrolling can be disabled with this preference.
  • Use smooth scrolling: Smooth scrolling can be very useful if you read a lot of long pages. Normally, when you press Page Down, the view jumps directly down one page. With smooth scrolling, it slides down smoothly, so you can see how much it scrolls. This makes it easier to resume reading from where you were before.
  • Check my spelling as I type: When this preference is enabled, Firefox will check your spelling and offer possible corrections as you type in web forms. Note that you may need to download a dictionary; to do so, press Ctrl and click on any text field, enable spellchecking if necessary, and then use the provided Languages menu to download a dictionary.

System Defaults

  • Always check to see if Firefox is the default browser on startup: Select this option if you want Firefox to check whether it is the default browser at startup. This will ensure Firefox is used whenever an application tries to display a web page. You can also click the Check Now button to do a check right now.

Network tab



Connection

Your organization or Internet service provider may offer or require you to use a proxy. A proxy acts as an intermediary between your computer and the Internet. It intercepts all requests to the Internet to see if it can fulfill the request using its cache. Proxies are used to improve performance, filter requests, and hide your computer from the Internet to improve security. Proxies are often part of corporate firewalls.

Connection Settings Dialog

  • No proxy: This is the default preference. Choose this if you don't want to use a proxy.
  • Auto-detect proxy settings for this network: Choose this if you want Firefox to automatically detect the proxy settings for your network.

  • Manual proxy configuration: Choose this if you have a list of one or more proxy servers.
Ask your system administrator for the configuration information. Each proxy requires a hostname and a port number.
    • If the same proxy name and port number are used for all protocols, check Use this proxy server for all protocols.
    • No Proxy For: List of hostnames or IP addresses that will not be proxied.
  • Automatic proxy configuration URL: Choose this if you have a proxy configuration (.pac) file. Enter the URL and click okay to save changes and load the proxy configuration.
    • Reload: The reload button will load the currently available proxy configuration.

Offline Storage

Pages you view are normally stored in a special cache folder for quicker viewing the next time you visit the same page. You can specify the amount of disk space the cache can use here. You can also immediately clear the contents of the cache.
  • Use up to ... MB of space for the cache: Allows you to specify the maximum size, in megabytes, of the cache on your computer.
  • Clear Now: Immediately clears the current contents of the cache, freeing the disk space used by the cache.
  • Tell me when a website asks to store data for offline use: Allows websites to store data necessary to be used without an internet connection. If you have previously blocked a website from storing data for offline use and changed your mind, you can click the Exceptions... button. Select the site you want to stop blocking, and click Remove. To remove all websites in the list, click Remove All Sites.
  • The following websites have stored data for offline use: After a website has stored data for offline use, you can select it in the list, and click Remove... to delete the data.

Update tab


Firefox can check whether updates to installed add-ons or to Firefox itself are available.
  • Automatically check for updates to: By default Firefox automatically checks for updates to itself, to add-ons, and to search engines so you'll always know you have the most up-to-date version. You can change this behavior by changing the appropriate checkboxes here.
  • When updates to Firefox are found,
    • Ask me what I want to do: Updates to Firefox are installed automatically by default. Select this preference to manually control how and when updates are installed.
    • Automatically download and install the update: When this preference is selected, Firefox updates will be automatically downloaded and will be installed the next time Firefox is restarted. The Warn me if this will disable any of my add-ons preference determines whether you will be warned before the installation of an update which would require an incompatible add-on to be disabled because no newer, compatible version exists. The warning will allow you to postpone installation of the update, though at the expense of improvements included in it.

      If all extensions and themes are compatible or can be updated to be compatible, the Firefox update will be installed. Upon restart you will be asked to install any needed add-on updates so that you can continue to use them.
  • Show Update History: Firefox automatically records the updates you have installed. You can view information about these updates by clicking this button.
    Note: You must be running Firefox as root or as the user who originally installed Firefox to install Firefox updates.

Encryption tab



Protocols

  • Use SSL 3.0: Specifies whether you want to send and receive secured information through SSL3 (Secure Sockets Layer, Level 3), a standard protocol for communicating securely with websites. Disabling it will prevent you from visiting some sites.
  • Use TLS 1.0: Specifies whether you want to send and receive secured information through TLS (Transport Layer Security), a security standard similar to SSL3 (Secure Sockets Layer). Disabling it will prevent you from visiting some sites.

Certificates

Certificates help perform encryption and decryption of connections to secure sites.
  • When a server requests my personal certificate: Some servers ask you to identify yourself with a personal certificate. In order to do so, they ask Firefox to generate one for you. When you visit the site in the future, Firefox will ask you for which certificate to use. If you wish to have Firefox automatically choose a certificate for you, select the Select one automatically preference.
    Note: A personal certificate can contain personally identifiable information, such as your name or address. It may therefore harm your privacy if you select the Select one automatically preference. If you do, you will not be alerted when a website request your personal certificate, and you may lose the ability to control who can access your personal information.
  • View Certificates: Click this button to view stored certificates, import new certificates, and back up or delete old certificates in Firefox.
  • Revocation Lists: Firefox can use Certificate Revocation Lists (also known as CRLs) to ensure that your certificates are always valid. Click the Revocation Lists button to manage the CRLs installed on your computer.
  • Validation: Firefox may ask an OCSP (Online Certificate Status Protocol) server to confirm that a certificate is still valid. By default, Firefox validates a certificate if the certificate provides an OCSP server. Alternately, you can choose an OCSP server against which to validate all certificates. Click the Validation button to manage these preferences. You will most likely only need to change this if your Internet environment requires it.
  • Security Devices: Security devices can encrypt and decrypt connections and store certificates and passwords. If you need to use a security device other than the one in Firefox, click the Security Devices button.



How to clear Search bar history

The Search Bar is located to the right of the Location Bar. If you want to clear the Location Bar instead of the Search Bar, see Clearing Location bar history.

Over time, the Search bar history in Firefox can grow quite large. If needed, you can clear items from the Search bar history.

Clearing all search items

To clear all items, hold down the Ctrl key while you click on the input field of the Search bar, and select Clear Search History. Your Search bar history is cleared.
  • If Clear Search History is grayed out, that means there are no items in your search history to clear.


Clearing an individual item

To clear individual items from the Search bar history, click on the Search bar input field. Press the Down arrow key to scroll the list of items. To delete the highlighted item, press Shift+Delete.
