Usually when I start my browser for the first time, I have the Firefox homepage only. For two weeks ago, suddenly an extra tab show up when starting: A page with a commercial for installing "Avast Online Security & Privacy (Add to Firefox-button)". I use Avast, but I don't want this add-on. And I certainly don't want that extra tab every time I start my pc. I have three times searched for a solution all over in the Mozilla & Avast settings and on the net: I should go to "Add-ons and themes" - "Extensions" - and on the list "Manage Your Extensions" I should remove this add-on - but it's not there of course, because I didn't install it. So how do I remove this tab from showing at start-up? (Google Search can't help) Appauling that someone put this tab on my pc in the first place. Both Avast and Mozilla have other ways to communicate with me about that add-on, if needed. Now I had to shut it down every day for two weeks, because I was way too busy to write you until now. Hope you can help me. Best regards Finn Larsen finn@fatekst.dk
