New tab's url "isn't valid and cannot be loaded"

Posted

When I click to new tab button I get a 'problem loading page' notice. Instead of showing me my most recent visited pages, the screen says that 'the address isn't valid'. How can I get back my list of thumbnails? When I go to about:config and search browser.newtab.url, it is already about:newtab. HELP!!!

Try to reset some preferences to the default with the SearchReset extension:

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).

Nothing. When you install the SearchReset extension then it runs ones and should uninstall automatically, so you wont see it in Tools > Add-ons > Extensions (about:addons). If this didn't help then 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 consider to reset Firefox.

If you reset Firefox then a new profile is created and some of your data (bookmarks, passwords, cookies, form data) is automatically imported and your current profile will be moved to the desktop (Old Firefox Data).

You can recover more data from the old profile (be cautious with doing that).

Do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

If you keep having problems then also create a new profile.
