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!

For the last two days and multiple times loading the firefox browser, it has taken about five minutes for the browser to load on our Dell Inspiron desktop, running Windows 11. Nothing happens for about one minute, then the spinning blue circle appears, then firefox starts to load, then the screen goes back to the desktop, then a black screen appears, then some white rectangles start to appear across the top of the screen, then the screen goes back to desktop, then back to the black and white top-of-browser window that is still trying to load, and then finally after the five minutes, our home page loads. However, clicking on a bookmarked website, or typing in a website in the address bar results in a 2-3 minute wait for that site to load. And this happens time after time with the computer still on, and also startup after startup. If this should continue for a few more days, we will start using Google Chrome or Microsoft Edge, and also cancel our subscription to Mozilla VPN. This cannot continue!

About a month ago, I started having a problem where all pages on YouTube randomly stop loading. It does this with no rhyme or reason and usually for around a minute at a time. It just hangs until it abruptly starts working again. Occasionally (like if I try to log out while this is happening), it will give me an error saying I'm "offline", even though I am most definitely not offline. During this time, all other websites (Google, Wikipedia, Hulu, etc) work fine, so I know it's not my Internet. Other than that, it doesn't give me any errors.

I am using a MSI laptop on Windows 10. Oddly enough, YouTube loads properly in incognito mode and in Windows Edge, but clearing my cache and cookies, disabling my extensions, and updating Firefox to the latest version didn't solve the problem. I even enabled each of my extensions separately in incognito mode while YouTube wasn't loading in a normal window, and each time YouTube loaded properly in the private window while simultaneously not loading in the normal one, so I know none of my extensions are causing the problem. Restarting my computer also didn't do anything. This problem persists when logged in or out of YouTube, no matter the account.

I reported this issue to YouTube back on December 29, but it hasn't been fixed. I also made a post on the YouTube Community a few days ago, but I didn't get any helpful answers. Any help would be appreciated!

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 :)

When I use firefox, it gets slower and slower over time to the point where it's a chore just to type. And this is on a recent MacBook pro. Everything else is fast. But Firefox gets unusable. The UI should not be a bottleneck like this.

Retarting speeds it up for a while, but then it gets slow again in a few hours.

Is there some kind of profiling I can run that I can use for filing a bug report?

Firefox is slow; so slow I have to use another browser, Brave, to get around this.

It is not about 'how many open tabs' or 'what extensions are doing'. I can have one profile open with one tab and still wish there would be a better response.

I have lots of profiles. I think the performance was better when I first started Firefox on this computer. I wonder If I eliminate profiles will I get a better performance.

How do I go proving this? - How easy can I take the profiles folder copy and rename it then start firefox with a profile folder and only one profile and one tab then What?

I did not gain a significant advantage in the load times for firefox. The load time for the browser with only the one empty tab 22 - 26 seconds . The load time for yahoo.com main page 31 -36 seconds. The load time for a link on the yahoo main page 20 - 22 seconds.

The question was "does having a large profile folder slow response time for firefox"? I believe I am seeing that this is true. When I load the yahoo profile it can take 10+ seconds more to resolve the main page and up to an addition 5-7 seconds to resolve the opened tabs.

Know that the browser was the only user process opened at the times of the tests. Know that the internet connection is the primier package and I have been monitoring the speeds frequently recently. I am good with the internet connection times. Know that I know the quick fixes and either there was no improvement or the inconvience of doing with out dark reader is no option.

Now understand I did not run these tests through a testing suite. These test were a couple one offs I used to form an opinion. Everyday usage forms an opinion in everyday users without hard data to coincide with the usage.

In the last few weeks FF has started running really slow. Launch takes 4-5 minutes, the browser won't navigate to any webpages. Preferences can't be opened. The force quit window show the app to regularly moving in and out of a "not responding" state. I had version 95.0.2 installed (the latest). I'm running OSX 10.15.7 (catalina). I uninstalled an reinstalled 95.0.2 and the same problem persisted. I downgraded to 94.0, and created a new profile in the process, and still had the performance problem. Chrome and Safari don't have the problem, and my machine is running as expected with all other apps. I don't have any sites load upon launch. I have 16G of RAM.

Since I can't open prefs, I can't purge caches or anything like that.

For quite a while I am using Firefox and had no issues, but recently, with new version , I am constantly facing two issues 1. the initial load of a page takes more then 30 seconds , sometimes 1 minute, but after the first page has been loaded if I open another page , it will be as usual 2. Completely random and without any sign of slowing down the OS - the OS freezes - nothing works at all and I have to restart it using the power button. ( and this happens when Firefox is open so I doubt Firefox)

version Firefox Browser 91.0.2 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Can you put one of those hourglass "wait" symbols to show on the next update because I never know if Firefox has booted or not and if you hit it again, it corrupts the next boot and wastes a bunch of time.

Ever since I updated, typing has become incredibly challenging... There's big delays in the words showing up, letters come out in the wrong places, & it doesn't improve even when I clear cache, clear memory, & refresh pages. I don't know what else to do. Should I delete and re-install Firefox, or replace this with the previous version?

One site that I visit is freezing up. This has only started to happen in the past two days. The size is Adam4Adam.com. I have tried troubleshooting mode. I have cleared my cache and my cookies. The site in the process of loading up freezes. What's more, is that not only that site freezes. All my open tabs in Firefox freezes when I load that site.

Please let me know if you can help.

Many thanks.

Searched the forums and web, no one seems to have answer that I have found. Firefox 95.02, Windows 10 Pro, 8 GB RAM, Dell Notebook, fiber optic Internet 156 mbps Start by running CCleaner, disable un-needed startups, extensions, ad-ons, ect., then roboot, have clean slate. About 3 months ago, after about 15 minutes Firefox slows down, then quits loading images, then eventually quits loading whole pages. If I was blocking content it would not work for at least 10 minutes. This evening, 21.38 clean boot, start FF, go to Facebook, read notifications, 1 tab open, nothing else running 21.55 images fail to load, still one tab open Researched more and ran about:memory, memory-report.json.gz unable to figure out how to upload Run CCLeaner, I do not save cookies or cache after FF closes, reboot 22.04 start Firefox, 1 tab open nothing else 22.16 images slow loading 22.20 nothing loads, try other websites like NOAA radar, all fine Reminds me I saw at the bottom left "Waiting for static.xx.fbcdn.net" Screen shot of Task Manager attached, FF running 10 times, 154 kb image will not upload Failed to upload, copying this txt and starting over. Images loaded fine after reboot Facebook works fine on Edge, I do not have/use Chrome or Google Facebook is the only page Firefox has issues with.

Hi, for the past week whenever I open Firefox (FF) it works normally for about two minutes, then slows, then causes my entire mac to slow and freeze. If I don't force quit FF quickly, my mac crashes. Once I force quit FF everything is fine. I've been using Chrome for the past week or so hoping FF would fix itself with an update but no go.

Anyone else having this issues?

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!

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

Hi can somebody help me please? Sitting here on Christmas Eve at work trying to fix Firefox.

In a nutshell I have a really really annoying bug with Firefox which is going to cause me to pull all my hair out.

In the past the program used to check for updates and it used to work fine during this procedure.

Lately though I've been experiencing a really strange bug.

Whenever Firefox checks for updates the browser then cannot load a single webpage or anything while it is checking. Sometimes the checks can take around 3-5 minutes to complete.

Any videos or streams come to an eventual halt.

I have tried tweak a few settings in about:config such as app.update.interval

I have tried uninstalling and re-installing the browser - No change. This still happens usually about 5-8 times a day.

This computer is used for medical emergencies for our clients. We need a full functioning browser. I thought Firefox was that browser but I am beginning to think about installing something else now.

In these situations lives could be put at risk and I want to remedy this problem now before the new year. I imagine we will have a lot of patients coming in. I need to quickly submit forms at times and I really need a stable browser.

a) Can I turn off updates? I would prefer to check manually for updates once a week or so via Help -> About b) Can I reduce the frequency of the checks for updates? c) Is this going to be a normal feature for Firefox from now on?
