Firefox on Android keeps forgetting my location on the page. I'm just reading Wikipedia articles, nothing fancy, but often when returning to the page Firefox is unable to return me to where I was reading before. Wikipedia articles have subsections that are expanded on demand on mobile. Firefox has limited ability to remember which ones were expanded and can never position the location of the viewing arev in the right place on the page. I am all but certain that this is a regression from the past few months / the most recent big release because I don't remember this being as frustrating before.
