After updating to the new Firefox revision the Tab button no longer works when getting between text fields to enter in information such as shipping address, name, and stuff like that where a simple TAB would navigate you between text boxes.

被選擇的解決方法

Hello benpierce25, try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • click the menu button New Fx Menu, click Help Help-29 and select Restart with Add-ons Disabled.

When the Firefox Safe Mode window appears, select "Start in Safe Mode".
Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.


The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then delete the User.js file, to see if the problem goes away (some programs create and write in the file also).


thank you

You can check the content of the user.js file with a plain text editor (right-click: Open with) if you didn't create this file yourself. The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js and possible numbered prefs-##.js files and rename (or delete) the prefs.js file with Firefox closed to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release. See also:

You can use this button to go to the currently used Firefox profile folder:

Windows hides some file extensions by default. Among them are .html and .ini and .js and .txt, so you may only see file name without file extension. You can see the real file type (file extension) in the properties of the file via the right-click context menu in Windows Explorer.
