dom.ipc.processCount and dom.ipc.processCount.webIsolated to your number of threads on your cpu
gfx.webrender.all to true
fission.autostart to true
I think it would, in my suspicion, make a better use of your cpu (the threadpool would be more efficient in the processcount), using the new renderer (webrender) and possibly make it a little more secure with one thread per website (or something, i don’t remember exactly) using fission.
One thing, always use hardware acceleration.
Does it get better if you set in about:config:

Edit: An explanation on webrender
Making those changes didn’t resolve the problem
Can you test a newer version of firefox? I have 128 ESR on my work laptop and it’s slow there too, it might be this.
This is apparently the latest version of Firefox ESR that’s available in Debian’s repository.
I used these commands to update Debian:
sudo apt update -y && sudo apt upgrade -y && sudo apt autoremoveHere’s the output:
Reading package lists... Done Building dependency tree... Done Reading state information... Done Calculating upgrade... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Reading package lists... Done Building dependency tree... Done Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.Ah, a newer version without being ESR. I found this from the Mozilla website:
https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended
I opened Firefox 134.0.2 (64-bit) that I installed via Flatpak—got the same slow pop-up issues.
Yeah, so it might be something else, IDK. Good luck!
Thanks but I want to stick with the ESR version. It’s nice n’ stable.
