Troubleshooting information page to fix Firefox issues

Firefox includes a page with information such as which Firefox version you are using, any installed extensions, important modified preferences, and graphics information.

Accessing the Troubleshooting Information page

Click the menu button Fx57Menu , click Fx57Help Help and select Troubleshooting Information.

You will be taken to a page with the address about:support.

Give Firefox a tune up

The Refresh Firefox feature can fix many issues by restoring Firefox to its default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.

Try Safe Mode

You can restart Firefox in Safe Mode to temporarily turn off hardware acceleration, reset some settings, and disable add-ons (extensions and themes) that might be causing problems. See Troubleshoot Firefox issues using Safe Mode for more information.

Try clearing the startup cache

Firefox stores certain temporary data in a startup cache to improve startup speed. Clearing the startup cache and then restarting Firefox can sometimes fix various issues, such as mixed languages in the user interface after an update. This will not change your profile data or add-ons.

Copy to clipboard

You can copy the contents of this page to the Windows clipboard. Clicking the Copy raw data to clipboard button will copy the source data in Json format. Clicking the Copy text to clipboard button will copy a version of the same data in report format for further use. (For privacy reasons, the Application Basics Profile Folder line will not be copied.)

After copying, you can paste the information into another window for someone to see by clicking the Edit menu in the program you are using and then selecting Paste (or by holding down the Ctrl key and pressingV).

Firefox Features

Some features included in Firefox, such as Pocket and Firefox Screenshots, are installed as extensions so that they can be updated separately from Firefox. These extensions (sometimes called system add-ons) are not listed in the Add-ons Manager.

I get a Warning Unresponsive script error

“Unresponsive script error”? What does that even mean?

Firefox may give you a “Warning: Unresponsive script” prompt that says “A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.” This article describes why this could happen and possible solutions and workarounds.

Webroot Spy Sweeper

Webroot Spy Sweeper can cause this problem. Disabling Spy Sweeper’s Tracking Cookies feature (or disabling Spy Sweeper altogether) can solve the issue.

Letting the script run longer

If you find that pressing the Continue button brings up the same dialog again, letting the script run longer won’t help you; it will just make Firefox hang for longer. However, if you can use Firefox normally after pressing Continue, then the script may just needs extra time to complete.

To tell Firefox to let the script run longer:

  1. In the address bar, type about:config and press Enter.
    A warning page may appear. Click Accept the Risk and Continue to continue to the about:config page.
  2. In the about:config page, search for the preference dom.max_script_run_time, and double-click on it.
  3. In the Enter integer value prompt, type 20.
  4. Press OK.

With scripts now allowed to run for longer times, you may no longer receive the prompt.

If you still receive the prompt (or if you want to see it again), you should set that preference back to the default value.

  1. In the address bar, type about:config and press Enter.
    A warning page may appear. Click Accept the Risk and Continue to continue to the about:config page.
  2. In the about:config page, search for the preference dom.max_script_run_time.
  3. Right-click on it and choose Reset.

Error happens when accessing certain websites

If the error happens only on a specific website, you can block scripts from running on that website. Many sites still function even if scripting is disabled.

  1. Install the JavaScript Toggle On and Off extension.
  2. Click the menu button  , click  Add-ons and select Extensions.
  3. Find the JavaScript Toggle On and Off entry and click the Options button.
  4. Scroll down to the Black-list text box and enter the URL of the site that’s giving you problems.
  5. Click Save. The domain name of the site will be added to the list.

Now that the problematic site has been blocked from running scripts, it will no longer cause unresponsive script warnings.

Firefox takes a long time to start up

Change the home page

Problems with a website can cause Firefox to take a long time to start. Try changing your Firefox home page to the default home page or a blank page.

Check your antivirus software

Firefox reads a number of files normally during startup. Some antivirus software may do intensive scans of each of these files during startup and block access until those scans complete. If the problem began after installing, updating, or reconfiguring your antivirus software, contact the software provider for assistance.

Troubleshoot extensions or themes

Firefox loads extensions when it starts up and many extensions add startup tasks.

Check if you have malware on your computer

To resolve slowness problems not specifically mentioned above, you should scan your computer for viruses, spyware, and other malware.

Malware is short for “Malicious Software”. It is a term generally used for software installed on your computer that is designed to infiltrate or damage a computer system without the owner’s informed consent. Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of. This article describes what common symptoms are and how to prevent malware from being installed and get rid of them.

How do I know that my Firefox problem is a result of malware?

Symptoms are various and depend on the malware but if you have one or several of these behaviors, you may have malware installed on your computer.

  • Some ad popups display all the time, although you’ve blocked popups.
  • Your searches are redirected to another site in order to feed you content from that website and you are being disallowed from blocking them. 
  • Your home page has been hijacked. For more information on setting your home page.
  • Firefox never finishes loading or can’t load certain websites.
  • Firefox crashes or hangs a lot.
  • Firefox does not start.
  • Problems with connecting to Facebook
  • Firefox keeps opening many tabs or windows
  • Unwanted toolbars have been installed

Block unneeded content

Content you don’t need such as ads or tracking scripts can significantly slow down page loading. Firefox’s built-in Content blocking can make the pages load faster by preventing third-party trackers from loading.

There are also Firefox add-ons that can block content you don’t need, such as:

  • The Disconnect add-on blocks invisible webpage parts that track you online.
  • The uBlock Origin add-on blocks ads, trackers and other unneeded content while using less memory and CPU resources than other adblockers.
  • The NoScript add-on allows you to selectively enable and disable all scripts running on websites.

Fix firefox is already running but not responding in Florida

All of your personal settings, bookmarks, and other information are kept in your Firefox profile. Firefox needs an unlocked profile to start up, and if the profile is locked, it displays the message, Firefox is already running, but is not responding. This article explains what to do if you see this message and how to prevent it from showing at startup.

End Firefox processes :

If Firefox did not shut down normally when you last used it, Firefox might still be running in the background, even though it is not visible.

If you try to open it while it’s running, an error message will appear with the option to click Close Firefox. If that doesn’t solve the problem, restart your computer or try the following options.

Use the Windows Task Manager to close the existing Firefox process :

  • Right-click on an empty spot in the Windows task bar and select Task Manager (or press Ctrl+Shift+Esc).
  • When the Windows Task Manager opens, select the Processes tab.
  • Select the entry for firefox.exe (press F on the keyboard to find it) and click End Process.
  • Click Yes in the “Task Manager Warning” dialog that appears.
  • Repeat the above steps to end any additional firefox.exe process, if more than one entry is found, then exit the Windows Task Manager.
  • Start Firefox normally.

Initialize the connection to a file share :

If you store the profile on a file share, try accessing the file share beforehand using Windows Explorer.

Check access rights :

Firefox must also have the right to create files in the profile folder. The error can occur if you try to use a profile from a file system mounted with read-only permission (e.g. a remote Windows share which doesn’t have “Allow network users to change my files” checked).

To check if the profile folder has the proper permissions:

  1. Go to your Firefox profile folder.
  2. Go up one folder.
  3. Right-click on your profile folder and select Properties.
  4. Click on the General tab.
  5. Make sure Read-only is not checked marked.

Restore data from a locked profile :

If you are unable to unlock the profile using the above methods, use the Profile Manager to create a new profile and migrate your data from the locked profile to the new profile.
