I'd suggest you try refreshing Firefox, [[Refresh Firefox - reset add-ons and settings]]

You can check for recently installed suspicious or unknown extensions. Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> 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 *https://support.mozilla.org/kb/Safe+Mode *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes ---- You can open the <b>about:config</b> page via the location/address bar and search for prefs that refer to <b>ask.com</b>. You can reset user set (bold) prefs via the right-click context menu to the default value. If you do not keep changes after a restart or otherwise have problems with preferences, see: *http://kb.mozillazine.org/Preferences_not_saved
