Hi, open the 3-bar menu > Add-ons > Extensions: I see you have '''BeauTab''' installed, which may be causing your issue, so try disabling or removing it. You may then need to restart Firefox. https://addons.mozilla.org/en-US/firefox/addon/beautab/ Note: If you didn't install it intentionally, you can report it - [[Reporting extensions and themes for abuse]]. -------------------------------------- If that doesn't solve it, you can also check your Firefox Desktop shortcut for corruption: Right click on it > Properties, and in Target, make sure there is no sign of anything other than Firefox. If there is, delete that part of it. Or if it's easier, you can just delete it and recreate a new shortcut. More: [[Wrong home page opens when I start Firefox - How to fix]]. Another thing you can do is to search in your PCs programs - look for anything recently installed that you don't recognise, because it may be masquerading under a different name.

I removed BeauTab. That solved the problem. Thanks!
