Android? Go into the system app settings and make sure any sort of battery optimization is turned off.
Firefox
A place to discuss the news and latest developments on the open-source browser Firefox
It will just keep reactivating battery optimization, at least it's what I see on Samsung.
You may have to whitelist it from the settings
Haha, well... It's a Samsung Galaxy from Android 10 era and, apparently, it has terrible Settings. Whenever I try to say "Don't optimize" on any app, it changes the label, but only for a brief moment, which effectively does not turn off any optimization.
It could be that you have too many other apps in the background, and Android is essentially freeing up memory for other processes. If you have too many tabs open this could also occur. You could also have your battery saving options too aggressive, which also clears data from background apps. I'd look up something like "how to keep Android from stopping apps in the background" or something similar.
I've the same thing. This is a very old issue and it's still not resolved. It seems Android prefers Chromium based browsers as it doesn't happen there. I tried everything, nothing helped. So had to revert to Brave.
I noticed that many of them get mad when talk about brave browser. Don't know why !
strange, i started having this same issue on brave about 3 months ago. i installed firefox and am not having this problem. no battery / background restrictions set for either
Apparently something about the CEO. With Firefox not working properly and no support for adblockers on Chrome I don't see any other alternative.
This happens to me too, no matter how much free RAM I have, disabled battery optimizations, etc..
Only Firefox does it, other browsers are fine.
Yeah. Other browsers are just fine.
I assume it's just a major bug in mobile Firefox, although I haven't tried other versions like Mull.
Does it on my old and new phones, and my Android tablet too.
