Updated Firefox to 154. When I select Firefox, I get a notice that Firefox is already running. If I cancel, Firefox comes up but I quickly get a notice that Firefox is not responding. I tried refresh but that didn't fix it. If you don't have an answer, I'll de-install and then (maybe) reinstall. -JJM

Firefox both persistiently crashing and signing me out of everything

Hi, so since around update 153.0 i've had this persistient issue of whenever I am forced to re-open firefox (whether by an update, a restart on my computer or a crash) it begins to persistiently quit responding and will never work until i close it. After a LONG while of just trying to open it again, it begins to run, but it also signs me out of a good handful of things, so I end up spending 20+ minutes signing in on everything (considering 2fa on some of those things). This used to just happen with the big number updates, but tonight my computer had to restart and I experienced the same thing happening with firefox just loading and loading. I tried letting it sit and of course it did nothing, I attempted to use troubleshoot mode and there was virtually no difference (it was still frozen until i closed it). The only things I haven't done are the nuclear options of refreshing or reinstalling firefox (mainly because I have a lot of extension settings I would rather not lose because I don't remember all of it). I am writing this on a mobile tablet right now because my computer is still experiencing this persistiently, no matter what i do now, and it's becoming annoying because of the fact that i do have to sign into everything EVERY TIME now it seems. Extra information about my settings to answer some of the "do you have (this setting) on?" or other functional questions: -I keep cookies on and stored on the device -I have hardware accelleration off -I had several extensions on including ublock origin, but again, troubleshoot mode (which disables all extensions temporarily) had the exact same result of firefox hanging. Disabling certain extensions manually also didn't work. -i can't provide exact technical info on my pc since im not on it rn nor really want to deal with fighting it any longer tonight to write this but my computer is on the lower-end, but can still run and does run things like discord/steam fine; firefox started persistiently freezing after a fresh restart of my computer, and I didn't open anything outside of firefox and related firefox modes (ie private browsing) attempting to troubleshoot today. -last time i signed back in before it kept crashing constantly was 4 days ago I really hope this explains my issue well enough and I hope someone can give some advice on my next step forward. I'm becoming a little desparate for answers since i don't know how long this goose chase of constantly re-logging into everything the services i'm logging back into will tolerate, as one of my emails is now blocking my main 2fa method for some reason, so I'm a little worried.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

Why does Mozilla 154.0 always stall after a couple of minutes? It is a hell of a mess. I couldn't place this question without resorting to an older version of Firefox :-[[

Did anybody test V 154.0 anytime, at all?

I unfortunately updated a Windows 10 computer to this version of Firefox.

As such, I cannot provide you with troubleshooting information, because the new browser 154.0 does not work. At. All.

I did all the usual stuff like restarting the computer, the users of Windows OS junk are used to anyway. The Task Manager shows not less than 16 Firefox-processes, with a truckload of memory usage, having opened just one browser tab. Waiting for 20 minutes for firefox to show me the grace of continuing its operation didn't help either.

Any ideas?

Web-based metronome sounds slightly out of sync in Firefox

I've been testing a browser-based metronome in Firefox and noticed that the audio click can sometimes feel slightly out of sync with the visual beat. It isn't a complete audio failure—the metronome keeps running and produces sound—but the timing can feel a little delayed or inconsistent, especially when using it at faster BPMs. The site I'm testing with is TheTapTempo's online metronome. I'm trying to figure out whether this is related to Firefox's handling of web audio or whether the delay is more likely to come from the system/audio device. A few things I'm wondering about: • Could Firefox's Web Audio timing cause a small difference between the scheduled beat and when the sound is actually heard? • Could Bluetooth headphones make the problem more noticeable because of their audio latency? • Can Firefox extensions or hardware acceleration affect the timing of browser-based audio? • Is there a Firefox setting or diagnostic mode that would be useful for testing this? • Would comparing the same metronome in Firefox and another browser help determine whether the issue is Firefox-specific? I've also noticed that the perceived timing can depend on the audio output being used, so I'm not sure whether this should be treated as a Firefox issue or an audio-device latency issue. What's the best way to troubleshoot this in Firefox?

I am constantly getting Firefox is running but not o responding. Why when i go to chrome or click the chrome add on in address bar a say click on my amazon I con it opens right up with not saying google is running but not responding. why ca none of you answer the question and why can it not be accepted that it is a Firefox problem and not me. As i have said i have had these same desktop shortcuts since i got my computer on windows 7. up until this last version i never ever had Firefox say it is running but not responding. Like ic said i have done all that way said by Bugzilla Firefox help and still no real answer and no fix . I am tellin you it is not me it is a Firefox problem. why can this not be researched and find out why. I am sure i am nt the only one with this problem. Please i need a solution or ill stop using Firefox which i have for over 20 years but apparently Firefox does not care and thanks SOLUTION PLEASE

So normally firefox uses a reasonable amount of ram but sometimes the amount of ram usage almost doubles, then if I try to change tabs the program freezes. I then have to wait for firefox to stop using the excess of ram and return back to normal levels.

I believe this mainly happens when I have youtube or reddit open but I have no idea how to fix this.

I have already tried reinstalling firefox and deleting/changing extensions. The current extension i have on is adguard adblocker and no others.

I keep having problems with Firefox hanging or disconnecting. I have followed all the steps in the [Hanging] page, and I still have to shut it down and restart it often, sometimes as much as several times a day. I also frequently have to force quit the browser, or I get a message saying "Firefox is open, but not responding" when I try to restart it.

In support.mozilla.org/questions/1598971 it's still not clear how you're getting this. You seem to be posting this question from a perfectly running Firefox so it apparently starts up and works fine on its own.

It sounds it's related to your Windows desktop shortcuts, or their exact target perhaps — however without knowing their content (destination or commands run) there's not much more to do here.

If you have anything new to add to the questions in the thread above, please post in that original thread so anyone trying to help understands what this pertains to.

My summary says it all, really. There's not much more that I can add, except that I have used Firefox for many years and have never had this problem before. The index page itself is fine when I view it in Firefox. And if I right-click the page and view its source code, everything is there. Furthermore, I have no difficulty in editing the page in other browsers. (Since this problem arose, I have been using the Norton browser. But I have also been able to scroll down to the end of the source code in Google Chrome.)

First post. Not really a question.

I noticed last week that some pages didn't load, and Activity monitor showing Firefox app using 170-180% which I know is way too high. Forgot to check memory usage.

I rolled back from 154 to 153 by restoring it from backup, and same with the Firefox folder in ~lib/appsupp/, relaunched Firefox and cpu was back to 2-4% cpu with a couple of windows and tabs. I've turned off auto-updates.

On my system, something is wrong with v154.
