Can no longer use Firefox since update 128 on DEBIAN 12

Hello guys,

The trouble I ll present you might come a bit late, I've just never thought about asking on this forum (didn't even know that it exists lol) and I spent a lot time on tutorials trying to find the solution... lol 😩

My situation : I have a laptop with debian 12 stable. Early July, I updated my apps, Firefox 128 has just been released. Since the Firefox 128 update, I can no longer execute Firefox, I always get the pop up message :

Failed to execute child process (no such file or directory)

I've tried many times to uninstall & reinstall, purge & reinstall. Still the same "failed to execute... " message. all the subsequent updates (128.X and 129.X) haven't solved this problem...

On the other hand, Firefox ESR 128 works like a charm.

Is anyone in the same situation as me ? 😕

Wishing you a nice day :)

You will have to provide detail on the install process for your OS. How are your trying to run it? You can run strace to see what directory it's looking for. Try this--> strace -t -o firefox_debug.txt firefox & It shouldn't generate too much output to the log. The firefox_debug will be in the current directory you're in. I just created a test folder and ran it from there. see screenshot

What Desktop? X11 or Wayland?

Try downloading Firefox from Mozilla. Download, unzip, and 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

Debian only offers Firefox-ESR from its repository so presumably you've got the non-ESR version from elsewhere. If it was straight from Mozilla as a tar.bz2 archive you may be missing some of it's dependencies.

You can install via apt as detailed here: https://support.mozilla.org/en-US/kb/install-firefox-linux which automatically sorts such things out. If you've installed it as a snap or flatpack I'm afraid I haven't a clue.
