I’m going to use this guide to downgrade Firefox to something around version 127 or below because I did not have this issue with earlier versions of FF.
Btw where does Firefox store crash logs? I typed “about:crashes” in the URL bar but it says that “No crash reports have been submitted”. I have also used journalctl to find these errors but I’m not sure how relevant they are:
org.mozilla.firefox.desktop[15004]: Exiting due to channel error.
org.mozilla.firefox.desktop[49355]: [Parent 2, Main Thread] WARNING: g_strv_length: assertion ‘str_array != NULL’ failed: ‘glib warning’, file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:187
firefox-bin[49355]: g_strv_length: assertion ‘str_array != NULL’ failed
in firefox you could export bookmarks and passwords but be aware that passwords will be exported in plain text.
because its running as flatpak, the exported files should be somewhere in $HOME/.var/app/
Thanks

Am using latest version of firefox but I am running it directly (no snap, flatpak, …). I have zero problem with youtube videos

I am running Gentoo. Could be something Ubuntu related? Also is it possible that your Firefox profile was corrupted somehow and when you installed Thorium you got a fresh profile and that’s why it worked well?
For me sites like YouTube, Rumble, Odysee, and Bitchute work but unfortunately this version of flatpak Firefox is giving me problems.
An aside to the technical question of how to migrate profiles to older versions:
DO NOT DOWNGRADE FIREFOX BELOW 131.0.2 OR ESR 128.3.1, 115.16.1
I feel that given this recent vulnerability, it is important to make this notice.
Otherwise:
For migrating profiles between the same major version, Mozilla provides a guide for full profile migration. This also works with forwards compatibility. I generally wouldn’t try to go backwards however as many new major versions change the data format and contents of your profiles, which older versions have no idea how to interpret.
For downgrading, it’s best to export bookmarks, go through your important addons and backup the settings for each one that needs configuration, and take note of anything you’re previously modified in about:config to your preference. Perhaps take screenshots of your tab bar and overflow menu as well so you can recustomize them to your liking easily on the downgraded version.
Have you tried a fresh profile? I used a years old profile over multiple systems and it caused similar hangs that I could not figure out, until I created a fresh one.
Interesting, I have never tried this before.
I’ll try out your solution and get back to you.
If you want a more stable version firefox-esr could be helpful

I appreciate your recommendation but I’m boycotting Google and as much of its tech as possible—that’s why I was using Firefox.

It uses Google’s Chromium engine, that’s the problem.

It is primarily maintained by them but it is an open sourced project and there are other contributors.
Chromium may be technically open-source, but Google still controls it and has been caught abusing that power before. People concerned about privacy have good reason avoid it.
I’m using FF always the latest version in a .deb format, native, never had a problem, in YT or others videos site

I’m using MX Linux Xfce (Debian based), whenever a new FF is released, it takes a few hours or the next day to have it appears in my update
