How to completely delete yahoo search engine???
I've removed all the search engines except of google. Now 1)yahoo still appears sometimes 2)yahoo always appears when I input in the address line "frog.fan65" without quotes. I know that this request may be incorrect but WTF? where is google? why does it still shows yahoo even if it "was completely removed"
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. Now do the same in the computers Programs Folder.
Windows: Start > Control Panel > Uninstall Programs. Mac: Open the "Applications" folder. Linux: Check your user manual.
