Hello, Is that link popping up for you when you load up Firefox? That is not normal behaviour - it means that you have malware/adware that is hijacking your browser. First, did you download Firefox from the official Mozilla website? * https://www.mozilla.org/en-US/firefox/new/ * https://www.mozilla.org/en-US/firefox/all/ Look for any suspicious applications in your Applications folder and remove them. Also look through your Firefox extensions if anything suspicious comes out: * Tools (or [[Image: New Fx Menu]]) > Add-ons > Extensions If you don't have many extensions, you can try to reset Firefox. '''''Note:''' After resetting Firefox, you will lose any extensions, toolbar customizations, and some preferences.'' See the [[Reset Firefox – easily fix most problems]] article for more information.
