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.

Firefox freezes every few minutes for 10-15 seconds, even in Safe Mode. Task Manager shows one or two of firefox's sub-tasks as "Not responding" and CPU at 100%.

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 am afraid that I am very confused about the changes to this site. Are the FAQs the only way to learn about the changes, or is there some documentation I am not presently seeing?

In addition, what happened to my older account on this site?

Maybe I am more than confused. Maybe I am completely lost. Yes, my own stupidity might be a major factor for this confusion I am guilty of!

There is one menu short in a screen, when I use Firefox to my bank. The file "2021-02-14.png" is missing a menu with "Forbrugsoverblik Forbrugsagenter Etiketter" on black background. The file "2021-02-14(1).png" is the same <prt sc> but in Edge browser. The file "2021-02-14(2).png" is the same but in Crome.

The two last are correct with all menu'es. How do I get the same i Firefox? I have cleared cookies and cache without any result.

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.

After Firefox updated to version 86 yesterday a couple of my users are being prompted to select what they would like Firefox to do with a PDF file each time they download one. They set it to open in Foxit Reader and checked the box to do it automatically each time but it always goes back to the default setting. I confirmed that the Application settings in Options is set to use Foxit Reader for PDFs and I even followed the troubleshooting step for this issue and renamed the handlers.json file.

Also each time they try to download a PDF a prompt comes up asking for an admin password (see the 3rd image). These computers are on a domain, so the UAC prompt isn't unusual but we don't restrict them from being able to download files. But I'm having the same issue as well and I'm not on the domain, so I think this is more of a symptom then a cause.

Is this a bug in the latest update? I was troubleshooting a printer setting issue for them the day before yesterday. Did some testing on my computer and theirs, got it worked out that Foxit works best for their needs when printing a PDF from a web app. Then yesterday afternoon they began to have issues where they couldn't print at all. I checked it out and all of our computers updated to Firefox v86 and everything is now working differently now in terms of handling PDFs.

Thanks in advanced,

Josh

I don't remember exactly the date, but I think it started after a update(firefox/windows). The oldest pic I have is from 23/11/20. Firefox was running without no problems, then this started.

Gallery

The problem is High cpu usage from time to time. Making firefox slower and also freezing tabs. It's so annoying. Made me use Edge that runs incredibly smooth, I was impressed( I can even watch media in 1080p with no problem).

Then I noticed through the task manager that the 'Host service Windows font cache service' is always present, as you can see in the gallery. I didn't find anything related to that.

Tried starting in safe mode, refresh, uninstalled and installed today(24/02) and nothing worked. This is driving me crazy because I love using the browser.

My PC Setup is: Windows 10 Home i3-4130 8GB ram no video card

And I use the free avira antivirus.

Hello, all:

I thought I could try reaching out to see about why Firefox somehow reset itself or something earlier tonight then I lost some recent bookmarks with the bookmarks I had in the bookmarks bar so I had to set it up again and am not too sure of whether it'll happen again which I hope won't. Is there a simpler way or something so I can be sure to keep the bookmarks I have since I have quite a number of them? Hope this information helps you figure out the issue I had earlier and how to not have it happen again at some point which I hope won't be the case. Thank you in advance if you reply to this post.
