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 autoremove

Here's the output:

I opened Firefox 134.0.2 (64-bit) that I installed via Flatpak—got the same slow pop-up issues.

Once you have Flatpak setup you can run sudo flatpak install firefox

Also, is there a reason you are using Debian? If that's what you want then that is fine but it isn't something people use for the new packages.

I already have Flatpak installed and it has the same problem as Firefox ESR (which comes with Debian by default, if my memory serves me correctly)

Also, is there a reason you are using Debian? If that’s what you want then that is fine but it isn’t something people use for the new packages.

I have used Debian-based distros in the past like Mint and Ubuntu so I wanted to use Debian itself out of curiosity.

Just my troubleshooting tips:

Can you run a benchmark, maybe this one, so we can see it it's really a general thing not just something on that website? Also we can compare it to other computers, or you can see if changing a setting helps at all.

Can you see something strange in about:processes? Shift+Esc is its keyboard shortcut.

Can you try it in other browsers? Something Chrome like (Chromium, Brave, Vivaldi). Does this happen there as well?

I can't find anything suspicious but here's a snippet of it:

I used Ungoogled Chromium and it opens the pop-ups smoothly (so Firefox is causing the problem):

Why the benchmark is at 90fps? What happens if you lower your monitor refresh rate to 60?

Lowered my monitor's refresh rate to 60 Hz and it didn't resolve the issue

Also lower it in the DE settings. Are you on wayland?

Why are you using the ESR version?

I would either add the Mozilla repo or install the Flatpak

Edit: I saw your other comments

What desktop are you on?

I have Flatpak Firefox and it's giving me the same issue as Firefox ESR.

I'm using Firefox ESR because Flatpak Firefox started freezing after a couple of updates and ESR is super stable.

As for my desktop: Gnome - X11

I can't find that option in my login screen's gear icon menu. I think that the reason why I can't use Wayland is because I have a Radeon HD5450 graphics card that is 15 years old.

What's the rest of the hardware? Tried disabling hardware acceleration and see if it makes a difference?

I disabled recommended performance settings and hardware acceleration in Firefox and I'm still experiencing this issue:

Then it's not the GPU, as it doesn't appear to be using it in the first place.
