Long time Firefox user here - been on from the start (about 2005), and don't want to switch because I love some features like the Panorama View extension, Context Search extension etc, and it's always been a great browser.

Recently though (not sure if it's just recently, or I've only just noticed), it's so slow. I tried a brand new profile, no extensions, no settings changes, and it's the same. Example loading times:

bbc.co.uk/news Firefox: 14s Edge: 2s chess.com Firefox: 19s Edge: 4s chess.com play vs computer Firefox 38s Edge 2s

https://youtu.be/er9jBysL0vEFirefox vs Edge (YouTube)

So it's not my profile settings or extensions.

BUT, I tried it on a different user profile on the same computer (Switch User from the Windows Start menu), and it's fast!

Why is this, and what do I need to do on my user account to speed Firefox up (keeping my same Firefox profile)?

Thanks in advance.

Pretty much title.

Since about two weeks when I open firefox the browser freezes every few minutes for 10-15 seconds. Launching firefox in Safe Mode or disabling all extensions didn't help. When I open Task Manager during freezes it shows that Firefox is "Not responding" and when I open sub-tasks it's usually one or two causing the problem. When I close those either firefox closes completely or youtube or reddit crashes, leading me to believe it's something with those sites? Refreshing or reinstalling firefox hasn't helped. I'm on Windows 10 (all updates installed) and Firefox 84.0.1 (x64) as of the time writing this.

I hope someone can help and suggest something. I would hate to switch to another browser, but the problem has become unbearable.

Hi,

I'm trying to disable the media popup in windows 10, which appears when you lower your volume or skip a song or anything (see added image). I have a brand new pc and on my old pc i was able to fix this easily by doing this: go to about:config and change this: set media.hardwaremediakeys.enabled from true to false.

I did that now, with my new pc as well. But i just does not work, i restarted my browser and pc after changing it, i set it back to true and back to false again, it just will not work.

I googled this issue, but the only solution i find, is what i exactly the thing i described above, nothing else.

I have had Firefox downloaded for a considerable amount of time and had begun to use it as my daily browser, until I started experiencing issues, concerning the loading. I have experienced this issue in all cases when trying to open the browser through the desktop shortcut, other icons, and even the .exe file, and typically I will see a brief white screen of Firefox before it immediately closes again. Frustrating to say the least and a quick google provides no insight. I have attempted on multiple occasions to uninstall and reinstall, however to no avail, and have even tried to create a new profile, via the Run (Firefox.exe -P) but again with no success. Running the browser in Safe Mode (Shift) will also work for a split second with the dialogue opening and then instantly shutting. Any suggestion on a potential fix would be great.

Every 2 to 3 days sometimes longer, Firefox will randomly reset itself and close out all windows and tabs to a single window and different search engine. Restore last session is never available when this happens even though I have that selected and checked and it does work when I manually close out windows and tabs myself so i know that preference is selected. My search engine preferences are always reset and have to restore defaults as well. Mac os Big Sur 11.2

Thanks to anyone who can help me solve this sudden mystery. Long time user of firefox on macbook pro and mac towers.

I find it really bad, if i post a bug and you just archive without even try to fix the problem! It makes me extremely angry! Bad behavior!

Please stop that and re-open the case.

Jan Ps. same system (Lenovo Thinkpad X300 with Xubuntu 16.04LTS 64bit (account A) )now running Firefox 85.0.1 64bit can now print, I can't find any mentioning in release notes to how previous version 75.0 and now this one is different and why this one now can print.

It would be nice to get this solved, since other people here has had this one too and it seems to jump between versions and OS(linux an windows).

Every so often when I am browsing and go onto a website the text becomes all jumbled as if it can't read the font properly. This has only started happening recently. It definitely seems to be a font issue as when I copy the text and paste it into a document it reads perfectly and if I close the browser then open it again the text is back to normal. It seems to happen after I've been using the browser for a while.

So after the wonderful weather the east coast has got over the past few days. Internet is out with no eta when it will be fixed. So I have to use apple hotspot. Ive noticed on firefox I only get up to 2.5 mbps download speeds. If I do a speed test it shows 36 to 44 mbps . Booted onto my old ssd drive with the same version of windows ten and as far as I know firefox. Firefox works fine on that drive. Ive also found out microsoft edge also works fine on my main m.2 ssd . I have no idea why firefox would be so slow, its like its limiting my speeds . But I checked and the throttling is turned off. I tried to uninstall firefox and reinstall didn't help.

I have no idea why speed test.net shows im getting 40+ mbps and youtube videos or just surfing the web is stuck at 2.5 mbps. any help or ideas would be great. Thanks.

Hello! Our company has had this issue since May of 2020. out of 170 users, we will have 3 or 4 users per day crashing at random times. we cannot recreate the crashing on demand, its random times, random pcs. we are running the latest ESR version we do have a handful of PCs on the non ESR version also crashing. nothing in their extensions. we have tried running in safe mode and renaming the storage folder for some of the repeat users PCs but the crashing persists after a few days. we had all users refresh firefox but it will also happen again after a few days. we have tried setting a different home page for some users but they still get it. the only fix is to reinstall firefox and it will work fine for a few days but then will happen again. when they are in the crash cycle, nothing will get FF to open, only reinstall. FF is the default browser since some of our vendors require it. any help would be appreciated!

here are some of the users crash reports. I cant tell what is causing the crashes. we do have mcafee AV and have tested removing Endpoint security modules but still got crashing.

Not sure if this is the right place to ask, but I've got a problem. On both my towers I have the Stop Button (and the Reload Button too) installed because I hate that little dual purpose thing that looks like a worm in an apple (small a apple) and can't be moved out of the URL bar to the bar I want it in. The installation on the tower (Windows 10 and updated today Firefox whatever that is) is working perfectly. On the machine running XP, with Firefox ESR 52.9.0, both buttons have died. I have removed and reinstalled. Not a flicker of life. AVG has been intermittently badgering me and offering to remove them, but I always tell it where to go (even though it won't) and close the warning. The people at AVG don't seem to understand that a lot of people outside AVG don't accept their prog's fatwa on certain extensions. What I'm wondering is, is it AVG being sneaky, or is there a reason why two extensions working happily for several months should go legs up? AVG warns me on the 10 machine too, btw. But the buttons still work. Before I made the Final Upgrade to ESR 52.9.0, I had real Mozilla buttons, but these ones by kiheru are the only replacements I can find. PS for software reasons I need both XP and 10.
