(1) Page become blank and only show big firefox logo everytime i switch from other app. (2) after the page become blank, If you type new url in the url bar on this page, it doesn't go to your URL instead the page will refresh to the previous url. So you have to enter your URL twice. It look like some memory issue, but my phone has 12 GB RAM, run on latest android and hyperOS 3.0 This good browser become barely usable with this annoying bug. So please fix this issue.
