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.

Extensions are Firefox add-ons that provide additional functionality to Firefox. This section lists the name of each extension, its version, whether it is enabled, and its ID string.

Graphics

Firefox can use your computer’s graphics processor to speed up the display of some pages with video and animation, which is called hardware acceleration, and to display WebGL content. This section provides information about your computer’s graphics device and driver and will tell you whether hardware acceleration and WebGL are enabled or not in Firefox. Note that graphics features may be disabled because of outdated graphics drivers.

Media

This section displays information about your system audio. The displayed information will include your operating system’s preferred audio settings, as well as the audio input (such as microphones) and output (such as speakers or headphones) devices.
