Yahoo installed a Yahoo tab in my Firefox toolbar that I DO NOT want there- how do I get rid of it for good?


Yahoo took over my Firefox- help!

About two weeks ago for some unknown reason Yahool basically took over my Firefox. All of a sudden it was my preferred search engine, Yahoo! TAB shows up in my toolbar (can't remove it) and in general it's been doing some goofy things. I swear I didn't give out any permission for this, but I hate it and it's driving me crazy (actually temp swithched back to Explorer). Tried uninstall and reinstall, but it's still there. Read somewhere that Yahoo hides it's files in hard to figure out places so it can't be deleted. Can anybody help me figure out how to get rid of Yahoo? (ESPECIALLY THE TOOLBAR TAB AT THE TOP) Many thanks!

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

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 or otherwise make changes.

If you do not keep changes after a restart then see:
