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.

Greetings.

Whenever I click on a link to Facebook, the page manipulates the browser history, effectively disabling the back button by adding multiple instances of the same page. I read that Google addressed this issue with Chrome a while back, but I don't find anything about a fix for Firefox. Is there one?

Thank in advance. Bill

Hello,

I had a 300mpbs connection for download, but was never able to get past 200mbps. But now today, on installing a 1gig connection, I still cannot get past 200mbps. The installer blamed it on my PC's network card. But I just ran the same speed test with Microsoft Edge 64-bit, and I was able to get past 600mbps. So clearly, this problem is isolated to Firefox.

I am using the latest Firefox 32-bit. I have no addons installed. I am running Firefox on Windows 7.

After typing this post, I thought the 32-bit Firefox was probably causing the issue, so I installed the Firefox 64-bit, and the speed increased by 50mbps to 250mbps.

Thank you.

I installed Firefox on a MacBook Pro 13" (Mid 2012) with MacOS 10.15.7 Catalina. Before closing Firefox for the first time, I carefully opened settings and ticked "Restore previous session", under "Start" on the "General" settings page. But when I opened Firefox again, there were no tabs, just a "Welcome screen" as if it was the first time ever I use Firefox! This is extremely disappointing! I am really shocked! I had never thought that Firefox would screw me like this! I have been using Firefox on Windows and Ubuntu for many many years! I can add that it is Firefox 85.0.2. And now it updated itself to 86.0.

Hey,

on one of my notebooks (Thinkpad E495) FF occasionally crashes. This started happening a few months ago. Before I've been using FF on the same machine for years without any issues. It's pretty random but usually happens at least once a day, usually shortly after startup or wakeup from hibernate mode. A while ago it used to even crash back to back twice in a row meaning after I reopened it, it immediately closed again and only worked after I selected to restore the previous session after the 2nd reopen. Nothing is registered under about:crashes and I don't see any errors in the system event log.

I already tried to disable hardware acceleration and reinstalled FF completely without any addons besides a different adblocker. I cannot really reproduce the crash in safe-mode but don't really want to browse the web for possibly hours without an adblocker.

Any ideas what this could be or what else I could try? Maybe downgrade to a previous version?

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.

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?

I am running Ubuntu 20.04.2 LTS. I wasn't having any issues with Firefox until it crashed unexpectedly and showed the Mozilla Crash Reporter. Now I can't launch Firefox and only receive the Crash Reporter. I have tried uninstalling and reinstalling Firefox from the command line. If I attempt to uninstall Firefox from the Ubuntu Software GUI, I get an error that it can not be uninstalled because of unmet dependencies (although it doesn't list any missing dependencies). I have submitted a crash report with Crash ID: bp-fe22d740-064d-4990-a5ee-13c080210227.

Hi, I'm having login issues on a website. I use Firefox for my browser. I have a couple of add-ons and VPN. I have disabled them but it still does not work. I have tried Safari with no VPN and no joy there either. I have cleared all cookies, cache history, put tracking protection at standard and cleared cookies from the Profile Folder (read the article on Mozilla about this issue). I have taken Firewall off Mac and tried it withiut VPN. Still nothing. I have checked my ipad without vpn. I can login on that on Firefox (without vpn) but I want to use my macbook if possible.

It's strange because I managed to log in on the website first time no problem and then I logged out and back in again and it wouldn't accept the password change. it's for a course and the people organising it have reset the initial password again but I still can't log in (they can do it with my username as they have sent me a video showing me they can and saying that it must be my end).

I have previously had a login problem with another website with a 403 error but that works without vpn. This doesn't.

Any help would be greatly appreciated.

My Firefox will not open no matter what I try because it continuously tells me, "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

This error started happening because my Firefox originally wasn't saving the add-ons that I was trying to add. If I closed my browser and opened another one it would be gone. I tried refreshing the browser but that didn't help. I eventually tried reinstalling to see if that would fix the issue and then this error popped up and now I cannot stop it.

I tried reinstalling. I tried deleting the profile out of appdata, etc in hopes it would make a fresh one. I tried making a new profile by running it without opening the browser only to be given an error that doesn't save it. I'm at a loss on how to get my Firefox working again. It is my favorite browser and this is the first time I've ever really had a severe problem with it. Help!

Often when I do a search from the address bar, the search query is cut off at some point.

Say I want to search for "tofu quiche recipe", so I write "tofu quiche recipe" in the address bar and press Enter. This will often cause Firefox to search for "tofu quiche reci" or just "tofu qui". Even if the entered query, "tofu quiche recipe", is displayed in the address bar itself, it seems that the primary option in the drop down will have a certain delay in updating and say "tofu qui — Search with DuckDuckGo", and thus when Enter is pressed, Firefox will drop the last part of the query.

The issue doesn't happen when searching from the new tab page or directly from a search engine site, only from the address bar.

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?
