Somehow the Quiknowledge add-on (or is it a plugin?) reactivated itself in my Firefox browser. How can I make it go away for good? 

   I went into Firefox, checked the box to deactivate, and restarted Firefox. I even rebooted my PC. These steps were supposed to make it go away. Despite Quiknowledge no longer being listed as active, it continues to turn my Firefox pages into pages full of link ads.

Help!

I was able to fix this by uninstalling this program through Microsoft Windows.

However, I still have this same problem with the Ask.com toolbar.

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.

You can delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file 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.
