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.

I know this is a longshot. I used Firefox for the last couple of years with Seagull Scientific's BarTender software on my Windows 7 pc. Now my PC was wiped out and Windows 10 as part of my company's initiative to get everyone up to Windows 10. BarTender uses a driver to talk to your print drivers and provide a status back to the BarTender server and webpage that we use. After the move to Windows 10 Firefox will not work with BarTender. It works in MS Edge and Chrome.

 I've got a ticket into Seagull Scientific and I can foresee how this will go.  They will point me back to Firefox and then I'll get pointed back to the vendor.   I know it will be hard to find someone with a similar issue.  But maybe someone had some issue with another driver, etc that stopped talking to Firefox.   
I've tried to turn off all of Firefox's protection stuff that might be interfering and still not working. 
I have used Firefox and prefer it over any others.   But I also don't like the idea of having to change browsers depending on what I'm doing.   Besides, this software I have to regularly use.   So if I can't find a solution I may have to abandon use of Firefox.

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).

Is it possible to have a default container? When I open a site in a container, if I then use the open window to go to a URL that I have not assigned a container to, i would like this new site to open in a "default" container. I believe the Facebook container works like this, it only allows Facebook related sites to be opened in that container any other sites are open in a new window/tab. An example, if i open a bank URL in a "Banking" container, log off and click on another unrelated bookmark (say Mozilla help), It would be nice if it opened in a separate container I had assigned to be the default container.

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.

Some tabs crash at random. Cannot reproduce at will. Started happening ever since I've upgraded to a Ryzen 3600 CPU. RAM with the XMP profile passes the entire 2 hour-long 4 -pass Memtest86 without errors.

The crashes happen on all versions of stable Firefox and on Firefox Developer's Edition. They also occur if there are <10 tabs open as well as 100 tabs open. I have 5-6 very common extensions on FF stable (Bitwarden, Gesturefy, uBlock Origin, Facebook Container, Open Tabs Next to Current, Wikiwand, and the Stream Detector), but not a single extension installed on FF DE and still it crashes too.

Some of many crash logs: bp-87b13e5c-1bc5-4f68-864b-95d6b0210227 bp-1751032b-df93-404e-822f-c13020210227 bp-e7840772-f24e-439b-b56b-ca8c50210227 bp-629bbf6d-b007-4b4a-8b76-b2d5e0210227 bp-dd9c0c07-61bf-44a4-b5a6-9f4170210227 bp-07cf5b11-39c5-4802-a448-7e6920210227 bp-97139c27-1633-4bab-a876-1bc030210227

These are all just from today, and these are not even all of today's crashes.

System details: AMD Ryzen 3600 16GB DDR4-3200 RAM (XMP profile 2) MBO MSI B450 Tomahawk (latest Beta Bios v7C02v1H3 - happened also with stable BIOS, so I put the latest BIOS on if there are possible BIOS<-->RAM problems but still crashes remain) Nvidia GTX 1070Ti (driver v461.72) Windows 10 Pro 20H2 v19042.804

Any idea what's causing this?

Hi,

So anyone experience choppy/hsss and slow pc ..even the mouse going choppy when you have a few tabs open after a while?

My system is a:

Ryzen 7 3700x AMD x570 chipset 16GB ram RTX 2060 Samsung 970 Pro

And it's going turtle like with shuttering and all the goodies after 1-2 hours of beeing on, to have 5-6 tabs of youtube videos shows immidiately symptoms of this behavior(I have a video if you want some proof), I tried to find the cause, checked CPU/GPU/RAM/mobo/PSU/SSD ...everything

And then I open the same stuff with opera/chrome ...everything is smooth as butter, tried safe mode with firefox ...it's the same

Unless I restart my pc it's the same, tried 2x Re-install windows 10, nothing ...I thought my Sound Blaster Z was the issue, nop ...with the onboard(realtek) I get the very same behavior

So what's wrong with firefox? ..tried disable hardware acceleration, nop ...same behavior

Am I the only one having this kind of firefox behavior?

I've been trying for some time to determine why my main Firefox profile, the profile I use most of the time, has a lot of trouble when I use Google Street View. The Street View screen essentially freezes when I try and use it. But, taking a tip from Firefox help I opened up a new profile in a new browser. When doing so, the existing Google Street View problem disappeared completely in the new browser. I call my new profile in the new browser my second Firefox browser to use. My question is, can someone explain why the problem disappears in my second Firefox browser? Looking at the options window when I open the Firefox menu, I see a few differences between the two browsers. The big difference is the second browser has much less applications in it. It has 7 applications where as my first browser has 21 applications. Is this the possible reason why the second browser doesn't have the problem that my first browser does? If so, how can I delete some of the applications in the first browser to see if that is the problem? I'm trying NOT to refresh my first Firefox browser as refreshing Firefox caused much problems for me in the past. And, it seems some Firefox aficionado's do say use caution when using a refresh. So, can someone please explain why the one browser, the new second browser, is void of the problem that plaques my first or original Firefox browser? Thank you.

Today i turned on firefox running the latest ubuntu platform and had colored squares and dots all over the web pages. If I move the mouse or type the squares colored black, blue, aqua and green move with the mouse or typing all over the display like snow. I have gone over the troubleshooting steps, I have uninstalled and reloaded mozilla firefox. The only way I can stop this is to go to safe mode. I have downloaded two other browsers today and do not have this problem with the other two browsers, or with any of the software programs on the computer. Any ideas?

Hello,

Just updated after a long time from 66.0.5 -> 72.0.2 -> 86.0. This is what FF wanted to do for some unexplained reason so I just let it.

Now when I open a new tab in an open window I get a white screen and nothing works. Entering a URL in the bar or pressing any of the buttons like home does nothing whatsoever. Just a blank white screen.

This is why I LOATHE updating anything! The odds of breaking something that was working perfectly is VERY high. Proved the point once again. I used to let FF update itself and then got burned by the Quantum update that trashed ALL of my open session windows. Turned auto-update OFF after that so that could manually grab and save a copy of the profile BEFORE any update happens.

So how do I fix this or is it a legitimate BUG that should be reported (and how to do same)?

Thanks, Steve
