I regret to say that this issue has not been completely solved yet. Firefox still freezes from time to time. The good part is that Firefox 103 has improved a lot. With Firefox 102 (and 102.0.1) it was a question of time, 10 minutes, 20, sooner or later it would hang. With Firefox 103, some days it doesn't hang at all, and I can use it longer before it hangs. Still, it's an annoying situation, because Firefox 101 and earlier didn't hang on my desktop computer. I hope that Mozilla solves it one and for all.

EDIT: I have deleted the ~/.mozilla/ folder, as Harvey suggested, and reinstalled Firefox, let's see if that helps.

    I've been using firefox for a long time and I can say that deleting the .mozilla and .cache/mozilla folders is something I don't hesitate to do (or I just rename those two folders temporarily to do a quick test).

    This didn't work, it keeps hanging. 🙁

    Tangetially, I have been trying the Firefox Appimage (103.0.1) as a possible substitute, but after a few promising hours of use, it eventually froze. To those who are interested in the Appimage, let me tell you I found a few problems: I couldn't import bookmarks (neither in html nor json format), I couldn't download files with the Always ask you where to save files on. On the positive side, it was very easy to integrate the appimage in the KDE menu, icon included. Easier than I expected.

    Perhaps I will try the Firefox flatpak, but I don't expect it to work better than the .eopkg version.

    Today's updates include newer versions of Nvidia drivers. I suspect this is a problem between Firefox and my old Nvidia GPU (my laptop uses AMD GPU and there Firefox never hanged), so let's see if it helps.

      Thread necromancy!!

      I downloaded the Firefox Nightly 109 appimage, this is the third day I have been using it, not intensively I admit, and so far it has not frozen a single time, which is very promising.

      The last version of Firefox in the Solus repository, 107, unfortunately still freezes randomly.

      To Susan/SMG of the Linux Mint forums, if you are reading me, thank you very much for your efforts in solving this issue. 😃

        joluveba This FINALLY happened to me three times this week. wouldn't open tabs. sluggish. listless unresponsive, frozen. All the awful Firefox experiences I've read about here at the forum, and more, came home to roost for me. I wasted oodles of time trying to fix firefox...migrated stuff I needed to do to different browsers...
        ...then I found a solution that nobody mentioned and nobody tried: killed the app and relaunched it. Worked for me the rest of the day just fine. We will see if this method works today as well.

            brent When did it start? Firefox 107? In my case, the problems started with Firefox 102, I'm completely sure of that.

                joluveba whatever version it was before the last update (yesterday for me) then that's the version. Froze awful starting tues, wed, thur, fri but finally just relaunching it did the trick.
                **has not frozen after update

                  this has started happening to me too now, before i didnt have a single firefox crash in 10 years. the only change ive made apart from whats been coming thru the repos is to install the firefox multi account container addon. anyone else here using that?

                    Lucien_Lachance no container add-on with me. I havent changed other addons in a couple years.
                    Working Theory: maybe FF updates are not agreeing will all the hardening/config stuff I've done over the years? (long shot)

                        I installed Mint on an Intel iMac and yes indeed Firefox hung the Xserver, installed Brave and no issue. Something to keep an eye on.

                        Haven't used Firefox for a couple of months now, at least, since the freezing started. Haven't gone back since. Using Brave and pretty happy with it. In my opinion, the FF team botched it. Too bad, I used only Firefox until this.

                          elfprince seems like a series of bad decisions and its a shame. the whole thing is murky. it's a browser with a specific function so I'm glad I spread the wealth. Braves a good browser I used it for a long time.

                            I downloaded the Firefox Beta 108 appimage, I did some configuration (the same extensions I used in my Firefox eopkg), I opened a few sites, and bang! Frozen again. I have just deleted the appimage.

                            However, the Firefox Nightly 109 appimage has not frozen a single time, after a few days of use. Let's hope this is the good one. 😃

                              great, now thunderbird does it too, after todays update

                              brent did the current repo 107.0 freeze on you?

                              Definitely, yes. The problem in my computer started with Firefox 102, and I still suffer from it (Firefox 107).

                              Firefox 109 Nightly (appimage) has not frozen a single time since I downloaded it a few days ago, so I guess it's the one that will solve it.

                                  joluveba did you ever just kill the app when its froze, then relaunch it? It took me a few days to know I could do that but once I did the freezing stopped (until the next time I had to kill the app rinse/repeat) but it bought me several days. maybe it's the way FF occupies memory or something?

                                  edit: nevermind

                                      brent Yes I did. When I relaunched it, Firefox simply worked until it froze again, which could be in a few minutes, or a few hours. There was was a difference, when I killed Firefox with System Monitor and relaunched it, the first time it remembered the sites I was reading, but the second time it didn't.
