Hi! Recently, in my laptop, Firefox started freezing at every single startup; after force shutdown and restart, though, it works flawlessly each time, and for the whole duration of the session at the computer. Can anyone please suggest a solution?

My laptop set-up is practically identical to that of my PC, but the latter doesn't exhibit the same malfunction.

I've tried anything I could, including reinstalling the browser, removing all of my bookmarks (about 10,000) and addressing extensions (Decentraleyes, Default Bookmark Folder, Disable Tab Detach, Flagfox, I don't care about cookies, Keepa, Notifier for Gmail, Privacy Badger, To Google Translate, uBlock Origin, Undo Close Tab, Video DownloadHelper and Youtube's Annotations No More), but not even safe mode improved the situation in the least. Windows Defender also hasn't detected any malware and my web surfing habits are as safe as it gets.

The only deeper data I could gather is that the problem manifests with a progressive, rapid surge in CPU and RAM usage; the former, for example, is saturated to its total 16 GB in a matter of about 20 seconds.

My laptop is a Dell Inspiron 7586 with Windows 11 64 bit; Firefox version is the latest, 100.0, and, by the way, none of the recent updates has improved the situation.

Thanks to anyone who might come up with an educated guess!

Hi, for some version (now I'm using 77.0 and everything is fine), when the writings are on a white part of the video, they have grainy edges and are unwatchable. This does not happen neither with Opera, nor with Edge and not even with Chrome. Not even with 84.0.2 the problem was solved. I kindly ask for help.

I am Italian, sorry for any grammatical errors.

I am hoping someone from Firefox Development sees this and that something can be done for those of us who need to have several tabs open simultaneously. I often find myself engaged in research that for convenience requires that I have several tabs open which eventually leads to browser slow down, hanging, and sometimes a crash. Im convinced this is the correct analysis since defragging the ssd fixes it every time. I believe it would be very helpful if Firefox were to add a compressor to its file storage routine, first blush thoughts, possibly one compressed file per tab. When I get into heavy research I find myself defragging sometimes several times in a day, which temporarily fixes the problem. Any chance this can be added, or if anyone knows of a fix to this issue? rgds, j

In the past three weeks, I have been experiencing issues with the Firefox browser on my iMac MacOSX. First, the browser, after some amount of time of usage, seems slower. Second, if I keep windows with multiple tabs open overnight and then try to use them, they don't seem to function. The YouTube videos will not play. I can't move the tabs. I need to close the tabs and window altogether to get YouTube to function. Lastly, as of now, I can't even select and move tabs. I have never experienced this problem with Firefox on my iMac.

Prior to this I don't remember having these issues. What has changed?

Hi, since the last update, Firefox is taking a huge amount of memory and slowing everything else on my PC right down. Right now this support tab is the only webpage I have open, yet you can see in the screenshot there are 31 Firefox processes running, and over 1G of memory being taken. I've followed all the help threads and taken the steps in them - it's made no difference. Please can you help me find a way to tame Firefox. Also - I'm really not an IT expert at all so please can you tell me in very simple language :)

I have to go into task manager to stop background processors from freezing my computer. Closing background processors in disk and memory. Sometimes there are as many as 10 background processors running but it seems to be a only a few and can't tell which one's until I figure it out. Sometimes I can by the amount of usage. I have to do this several times as I use my computer.

It doesn't crash every time, but when it does, if I restart and try to save image/video/etc. again, it will usually keep crashing a string of times before it finally allows me to download without going "Not Responding" and at which point I have to force quit.

I've tried browsing other solutions but nothing seems to work or be applicable. I'm running Firefox 78.15.0esr (64-bit) on an El Capitan 2010 iMac.

Thanks for your help!

OS: Windows 10-64 Home or Windows 10-64 Pro Version 20H2 (OS Build 19042.685) with all current updates Firefox: 84.0.2 (64-bit)


For about a week now a few websites are taking a long time to load on my 4 PCs (examples: ebay.com, walmart.com, pch.com). If I click the link on the search page it takes almost 30 sec to load, right click and open in a new tab same time, and open a new tab and type or paste address the same amount of time. Most other website open almost immediately.

The issue does not resolve in safe-mode or if I manually disable add-ons. I'm using the default theme.

All websites load without issue on Chrome and Edge.

Just today, firefox began slowing down and soft crashing for minutes at a time. During this time, I can interact with websites, but it doesn't change the visuals or show that anything has changed. new tabs open but don't show up, youtube video audio plays but the screen remains fixed. Firefox usage for just 7 tabs is well over 5 gigatybes of ram and 10-20% cpu at all times.

I attempted everything on the help page, including: killing and restarting firefox, updating firefox, updating windows, restarting my computer, killing firefox and rebooting again, disabling extensions, and updating graphics drivers.

after rebooting with the new windows update, firefox ran smoothly for a brief minute and showed normal cpu/ram usage, but quickly climbed back up to pre reboot numbers.

Due to my work I often have several tabs open for upwards of 12 hours at a time. This being said, for some reason after roughly 8-14 hours of being open my internet slowly gets weaker and weaker, it never completely turns off, and the internet works perfectl for my browser, however other programs (discord, photoshop, minecraft, anything that uses a passive amount of information) slow down until I restart firefox completely. It sometimes slow my 70mb/s+ upload/download to .1mb/s measurable upload/download and if i can fix this somehow that would be wonderful.

Hi, hoping someone can help point me in the right direction....I have a web app that has lots of data, we run several scripts that can take a while to process.

Since the last Firefox update (92.0.1 64-bit), my bookmarks menu is slow to load, and also slow for navigating. It's slow to load the list when I open Bookmarks tab. And it's slow when I move my cursor up/down the bookmarks, it takes a bit for the highlighted bookmarks to catch up. It's very odd. I don't really have a lot of Bookmarks, I would guess ~500 total. Plus I am using plenty of RAM with Windows 7 on a SSD.

Bookmarks loading and accessing was lightning-fast prior to this last Firefox update. I have searched on this Forum for answers, plus Google.... no luck yet. I'm sure there is an answer. Does anyone have it?? Thanks for any help. Dave F.

PS - I LOVE Firefox. Many thanks to Mozilla for a terrific product! ;-)

I have used FF for years, now V82 on W7 starts out fine, but bogs down to point you can not type. I have tried all the fixes noted here without success. Monitoring both Windows Task Manager and FF Task Manager shows nothing unusual when this happens. Internet speed is 100MBS.

Turning off addons, limiting Tabs, clearing history, updating drivers, minimizing background programs, etc., has little or no effect. FF just bogs down, and usually doesn't recover until restarted.

This appears to be particularly noticeable on ebay, but does happen at random on other sites. Where else can I look for a clue to what the problem is?

Hello Firefox Team,

I use Windows 10 - 20H2 version and Firefox latest version.

In the last time, i got error on firefox. firefox cannot display some websites. Firefox is experiencing a delay in responding.

For example myvideo: https://youtu.be/jILxKYqspew

Step 1: Visit : tmconsultancy.com or denetcilerymm.com.tr (any website) Firefox: waiting response Step 2: open edge and visit tmsconsultancy.com (fast response) . I have been experiencing this error for the past 1 year. I completely force uninstalled Firefox and clean installed.The problem was not fixed.

However, i do not use any plug-ins or virus programs(on firefox). This problem is very annoying.

Can you help me please?

Regards

I am facing a strange issue where the Browser doesn't load the website for a minute and shows server error. However, this behavior is not specific to any website and the server error shows randomly. Sometimes the browser loads the website normally while other times it shows server error. Please check this screencast: https://jmp.sh/jEu4D9k to understand better. So, I initially tried to open calendly.com and it didn't load despite my multiple reload attempts. However, when I tried to reload it after a minute then it came to life.

I have been facing this issue for many months and I tried almost every solution I found on Mozilla community pages like Resetting Mozilla, Setting No Proxy, Turning Off IPv6, DNS Prefetching Changes, Turning On/Off hardware acceleration, Uninstalled Mozilla and Installed a fresh copy, Changed to Mozilla Developer Edition, etc. but no luck. Please note that the other browsers are working fine and don't have any issues.

For 3 days now, I have not been able to view or use anything in my Facebook account. The page would drop the internet because it was too slow. I have tried various things from support and also received 1 from the community. it has not worked so I am going to switch to Microsoft Edge because I did not experience this problem with ME. I have used Firefox for years but the slowness is very annoying. I will try it again in the future. Thank you
