Hey all, Before I go to far, here... Firefox version 127.0.2 (64-bit) Windows 10 Version 10.0.19045 Build 19045 Extensions - Malwarebytes browser guard. What I've done: Cleared cache, history, etc. etc. ran multiple system scans restart app restart windows So how do I keep Firefox from opening pop-up for about:config? That's right, There are pop ups that firefox allow to open new tabs, and its the about:config page. Also, every time I start typing out google in the address bar auto suggest fills in googleleadservices or something like that. I already went through all the same steps above and more. I originally thought it was just opening one of the last pages I went to, but if I've "cleared" everything as per the way firefox has it set up, why would it have any history of what the last page was?
