Hi. I haven't been on my computer for around a month, and when i come back and search something on firefox, it uses Yahoo! as search engine. I have set the default search engine to Google, which is my prefered search engine, but it still uses Yahoo! Is this because firefox has changed something, or have i downloaded something that controls my search engine? I have a MacBook Pro running macOS Sierra, and the latest version of firefox. Thanks!

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Remove “ Yahoo “ Anything. Also look for SafeSearch or SearchAssist Incognito.

Now do the same in the computer’s Programs Folder.

Windows: Start > Control Panel > Uninstall Programs. Mac: Open the Applications folder. Linux: Check your user manual.

The System Details list shows this extension as the likely culprit.

  • "WebSearch Yahoo Extension"

There is no "Yahoo!" item in the about:addons page. So I'm lost now. What do I do?

Hi WestofYouLB, thank you for posting a new question and sharing your extensions list: https://support.mozilla.org/questions/1175699 (I think the problem is the one with "search addon" in its name)
