Ublock origin is way more than a Ad blocker. It also blocks lots of other things including site hijacks though multiple redirects and redirecting tracking links.
Was the same for me at first but in the setting is button which pings the instances. I just checked everything with a green number and unchecked everything with a red number. After that it worked.
Has anyone else found the firefox app on android buggy? Always crashes when switching to full screen when watching a video but will work when opening it again immediately. Gets into the wrong state with private vs non private tabs etc.
Video sometimes fails to play when coming back to it. I need to restart the browser. However the rest of the page is responsive and I haven't had it crash.
