Firefox

AdGuard/uBlock aren't very different from each other. I've used AdGuard for a long long time, and the browser plugin isn't their only tool I'm familiar with.

If I need better isolation between active sessions, I either end my current session or hop in a VM. Firefox containers are far from perfect and not sure why it was mentioned.

Last time I did my tests, Strict + PP + PB altogether had my preferred outcome on modified/blocked data. Resist fingerprinting did not touch everything I wanted either.

I use UAS to access sites made for other platforms, not to avoid tracking

Decentraleyes: CDN's are not that simple. I have heard there is a better addon for this now though

I add/delete/modify multiple bookmarks a day, and noticed when i use menu-quit it hasn't happened since. Many applications used to clean up differently this way, so I'm not sure. But I do know memory management on different platforms is becoming more and more of a nightmare to track/utilize changes
