Occasionally, the website I am on will suddenly change to a different one (the same one all the time: questscan.com), and I have no control over it. I can refresh the page, press 'back' and reenter the desired webpage, but it will inexplicably go back to the undesired webpage. It doesn't happen all the time.

This issue is caused by the QuestScan extension (Tools > Add-ons > Extensions).

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
