Форум сообщества Firefox для Android

After I want to multitask on my phone and switch between the browser and other app. The page becomes blank and refresh button doesn't work.

I need to open a new card to continue using the website loosing all temporary changes made to it.

Redmi note 11 pro 5g with 6gb of ram

Issue was present for at least 6 months.

Firefox for Android is non-responsive on my Samsung flow HP PC screen. Please advise. All other browsers are responsive. Love Firefox thou, but can't use it on my PC (Samsung flow screen on the HP PC.)
