What happens when you run Firefox from Mozilla? Download, unzip, and run firefox-bin in the folder. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release X11 or Wayland?

I was able to fix the VA-API issue by following the instructions here: https://electro-dan.co.uk/blog/26/nvidia-firefox-hardware-video-decoding-on-linux-mint-21-%2F-ubuntu-22.04-%28jammy%29-va-api

But that only solved the missing VA-API. I still have all the other issues. I am on X11 (I had to search to find out how to get that info).

I am running Linux Mint 21.1, if that helps.

Another strange issue I discovered: If I have the window on the right half of the screen, I cannot move the Home icon next to the back arrow when customizing the toolbar. I have to move the window back to the left. Also, sometimes when right clicking, the menu appears for a moment, then the web developer tools open. Very weird.

Unfortunately, running Firefox from Mozilla has all the same issues. I am on X11 (something I am not too familiar with, since I had to search how to find out).

Another very weird one I just discovered. If I have the window on the right, I cannot move the Home icon to the left of the back arrow when customizing the toolbar. And even more weird, sometimes when right-clicking, the menu shows for a moment, then the web developer tools open.

In the other thread, you asked me to run strace -t -o firefox_debug.txt firefox &

I have the text file available. How do I get it to you? I tried posting the output in a post, but the forum won't allow it.

I have discovered that all of these issues don't appear if I keep Firefox on the left. There is also a half inch gap between the Firefox window, and the left side of the screen, when Firefox opens.

I forgot to point out that I am using Firefox v108.0.1, not what the op was using.

Your issue does not appear to be a browser issue if both versions failed. I would run a live usb stick or vm, it sounds like an environment issue.

I suppose it could be that. Unfortunately, running Mint from the usb is so slow, it is almost unusable. I haven't tried a vm yet. Firefox works perfectly, with no errors on the command line, from the live USB. Plus, Firefox worked fine until recently. Perhaps an update broke something.

In any case, someone from the Mint community is also helping me with this issue. If she comes up with a solution, I will post it here, to help others.

I forgot to point out that neither the repository install, nor the one from Mozilla, work correctly in safe mode either.

Note that you in that other thread you managed to post those two strace reports, but those replies ended up in the moderator queue and are hidden. You can post them in this thread and we will approve them or you can create two empty placeholder threads here and I can copy the content over.

Oh, I see. I didn't think they took, since I didn't see them posted. The next two posts will be empty.

Now it gets really weird. I just discovered that if I run Thunderbird, then Firefox, Firefox behaves properly. But only if I click the menu icon. If I run Firefox from the command line, it misbehaves again.

Thunderbird starts with a half inch gap on the left as well. I imagine both Firefox and Thunderbird have much code in common, since Thunderbird used to belong to Mozilla.

While Firefox (and the right-click menu) still opens on the left half of my screen, when it is set to open on the right, all the other issues seem to have been fixed, in Firefox 109.0. It even loads pages faster.
