Is this issue related to my ancient 15-year-old graphics card, my browser, or something else?
- deleted by creator - Making those changes didn’t resolve the problem - deleted by creator - 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: - 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...

- I opened Firefox 134.0.2 (64-bit) that I installed via Flatpak—got the same slow pop-up issues. - deleted by creator 
- What’s the system resource usable look like? 
 
 
- https://flatpak.org/setup/Debian - 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. - Once you have Flatpak setup you can run sudo flatpak install firefox - 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? - Can you run a benchmark, maybe this one  - Can you see something strange in about:processes? - I can’t find anything suspicious but here’s a snippet of it:  - Can you try it in other browsers? - 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? - I changed it via Debian’s Settings app. - I’m using X11 and Gnome. 
 
 
 
 
 
- It’s most likely the CPU or less likely a browser bug. 
- 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 - Have you tried switching to Wayland? - Log out and select the Wayland - 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. - Wayland doesn’t care much about underlying hardware as that’s abstracted away by the kernel level stuff. - Are you using GDM? - Edit: https://wiki.debian.org/Wayland#GNOME_.28supported_since_3.20.2B-.29 - It looks like Wayland is the default 
 
 
 
 
- 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.
