Hi. About two weeks ago, I started having problems with firefox (it started about the time I logged into different device through firefox account, not sure if it's relevant). Few times, it took a lot of system resources and once it almost caused my computer to crash. Right now when I open firefox, it runs fine and does not take too much CPU or RAM. What concerns me though, is that when I open process viewer (specifically ''htop'') I have around thousand firefox processes. Although most of them don't take any system resources, I would like to know what is happening. I use arch linux (I am sure it's up to day) with i3 window manager. What I tried: * '''''pacman -Rns firefox''''' and '''''pacman -S firefox''''' to reset it (I was suprised when al my configs stayed). I then tried to reset firefox through it's settings and even run it in the ''save mode/troubleshooting mode'' * I checked '''''dom.ipc.processCount''''' and it is 8. ''It is not caused by extensions, since reseting and save mode do not preserve them.'' I thank you for your help in advance.
