Hello, the Firefox app often stops responding when I have multiple tabs open or when a more demanding process is running in a tab. Also, Firefox stops responding when I copy a screenshot. I have tried the browser without any extensions and the problem persists. I use EndeavourOS based on Arch linux, I use the current version of the system and Firefox.

X11 or Wayland?

Try downloading Firefox from Mozilla, run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

I'm using X11, with firefox-bin downloaded from the Mozilla site I have the same problem.

Can you show the issue? We cannot help with what we cannot see. If both versions of Firefox are having issues... sounds like the environment is the issue. How about trying Waterfox? Can you run a VM or live usb stick? Do you have the same issue under another user? What are your computer specs?

In VM and liveboot it works correctly. In Waterfox and LibreWolf the problem is the same.

That's what I thought. Firefox from your distro and Mozilla have the same issue, then IMHO it's not the browser. Thanks for the video, but I couldn't clearly tell when the issue happened. It looked like it occurred when you saved the full page. Looking at your system specs, we are on the same version of most things and I cannot replicate your issue. From looking at the manual for your laptop, it looks like it can hold more than 1 drive. I would install another the OS (openSUSE) ;-)) or the same again on the 2nd driver (if you have it). I dual boot Win 11 on this laptop.
