Though I normally run Firefox on private mode, and do accept cookies but never from third parties, I seem to have somehow ended up with a virus or something that automatically changes these settings every time I use Firefox. No matter how often I uncheck the box next to 'accept third party cookies' and click 'okay' the next time I go into the privacy setting box it will be checked again. How do I fix this???

This issue can be caused by an extension that isn't working properly.

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).

If settings change after closing and restarting Firefox then see:
