This only works for the current session. If you Shutdown FireFox, then open it again later, all of those Bloody Search engines are still there. I only need one, and it sure is NOT Yahoo!! Bing is OK, and I have no use for eBay as a search engine. I need to get rid of those search engines that I do not use permanently!! Thank You for your suggestion though.

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

• Don't make any changes on the Safe mode start window.

Try to delete search.sqlite and search.json in the Firefox Profile Folder and repeat the deletion.
