On Firefox Beta for Android, 113.0b9 (Build #2015947331). I run 30-40 tabs. Sometimes when I switch to a tab it is no longer on the page I left it at. It is one page back in the tabs history. When I first switch to the tab the URL is briefly correct, and it's as of the Back button was hit. Forward is not an available option. It does not consistently happen, or I would have better repro steps. Maybe it has to do with the tab being loaded out of memory? This has been going on for a while now, a few months at least. I figured it would be fixed with subsequent updates but not yet, I have also had no luck searching for anyone else experiencing this bug.
