Is there a tool that reports what action or extension caused a tab to open? Just a 3-4 times a day I’ll come across a tab that’s been opened, initially from lzpv4rsmat dot com but always redirected, usually to the adult site best2018games dot com.
With 30 extensions and only occasional hijacking it’ll take forever to diagnose by disabling them, assuming it’s an extension. Avast, malwarebytes, and defender haven’t found anything (FF 62 on Win10 64).
I’m most concerned that something more malicious is also going on.
