Using Radeon HD 5450 and Firefox ESR (128.10.1esr - 64-bit) on Debian 12. Javascript pop-ups appear very slowly (files.catbox.moe)

Is this issue related to my ancient 15-year-old graphics card, my browser, or something else?

One thing, always use hardware acceleration.

Does it get better if you set in about:config:

  • 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.

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.

[–] KickassWomen@lemmy.world 1 points 1 week ago (2 children)

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.

[–] MRLimcon@lemmy.ml 2 points 1 week ago

Yeah, so it might be something else, IDK. Good luck!

What's the system resource usable look like?

What's the CPU and what memory speed?

[–] KickassWomen@lemmy.world 1 points 1 week ago (1 children)

CPU: AMD Ryzen 7 5700X

As for my memory, I don't know the speed and I doubt that speed is the problem here because when I use Ungoogled Chromium, the javascript pop-up opens smoothly.

[–] possiblylinux127@lemmy.zip 2 points 1 week ago

That's a powerful CPU so I doubt that is the problem. I just wanted to get the obvious out of the way.

[–] KickassWomen@lemmy.world 2 points 1 week ago

Thanks but I want to stick with the ESR version. It's nice n' stable.

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.

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.
