Every time a tab leaves focus, it refreshes

Whenever the app leaves the foreground, even for half a second, or if I switch tabs and then return to the original tab, it refreshes and I lose all the data on it. When I need to copy information to fill out a form, or get a code from a 2fa app, I lose all the the progress. This is driving me crazy and making it almost impossible for me to use Firefox as my main browser. I shouldn't have to restart a whole form because I got a phone call and went to the call screen for a second. Battery optimizations are all disabled.
