Your Firefox profile cannot be loaded. It may be missing or inaccessible.
Hello,
I've tried running "firefox -P". I've also tried deleting ~/.mozilla. No matter what I do, I still keep getting this message.
OS: Linux 6.10.13-3-MANJARO Firefox versions: firefox 131.0.3-1 installed from the Arch repo via pacman; also firefox-132.0.2 installed from tarball downloaded from firefox.com and unpacked as /opt/firefox.
With firefox 131.0.3-1, I get the following error message:
[Parent 33389, IPC I/O Parent] WARNING: process 33445 exited on signal 9: file /usr/src/debug/firefox/firefox-131.0.3/ipc/chromium/src/base/process_util_posix.cc:335
With firefox-132.0.2, no messages are printed.
What is even more confounding: I have 2 user accounts on this computer. When I login as myself, I get this popup. When I login as the other user, firefox opens up fine.
I've already looked at the following, but that has not helped. https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible https://support.mozilla.org/en-US/questions/1327628 https://support.mozilla.org/en-US/questions/1396772 https://support.mozilla.org/en-US/questions/1454745
I'd be most grateful if someone could please suggest any other alternatives to try. Thanks!

Note that Firefox also places files in the profile in the secondary location in .cache/mozilla/firefox Note that if you install Firefox in /opt, you need to run Firefox as root (sudo) to be able to update.

Using firefox -P in a Terminal window should open the Profile Manager dialog so you can create a new profile or switch to one that still exists. Is Firefox ignoring the -P parameter, or not letting you create a profile?

@jscher2000, Thanks very much for taking the time out to suggest a solution. I was getting the error message in a popup window when running firefox either with, or without the -P option. It turns out a corrupted ~/.cache/mozilla/firefox directory was the problem. Solved now. Thanks again!
@cor-el, a corrupted ~/.cache/mozilla/firefox was the problem, I'd forgotten this secondary location. Many thanks!!
