Try to use the SearchReset extension to reset some preferences to the default values.

Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

Thank you have tried what you said but it has made no difference. Also the add-on you sugested, has failed to instal

You won't see the SearchReset extension in "Tools > Add-ons > Extensions" because the code only run once and the extension automatically uninstalls itself, so this is expected behavior.

You can check for problems with preferences and rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default values.


You can try to create a new profile or reset Firefox.

If you reset Firefox then a new profile is created and some of your data (bookmarks, history, cookies, passwords, form data) is automatically imported and your current profile will be moved to the desktop (Old Firefox Data). You will lose extensions and other customizations (toolbars, prefs) that you've made.

It is possible to recover more data from the old profile, but be cautious to avoid carrying over the problem.
