Firefox Support Forum

Hi! As the title states, since the latest windows update (am now on 19041.508), anytime I go on a webpage on Firefox it's extremely slow to load, however once loaded the page is as fast as it should be!

I don't have any antivirus other than windows defender, and disabling it/the windows firewall doesn't fix the issue, so it doesn't seem to be linked to that either, on the online forums such as this one I found it was also common to have issues caused by hardware acceleration, playing with that setting does not help either.

Another friend of mine has the same issue as me since the last update, so I'm assuming it's not something unique to my situation, is this a known issue for which a fix is available? Searching for one has yielded only outdated results.

Thanks a lot!

Hellow,

Since updating the latest firefox version 91.01 it has considerably slowed down browsing speed to an impossible crawl. The task manager shows the update as permanently on, sucking 100% resources. There´s something not right when it does this, and is becoming a bad habit of constantly refreshing firefox to get sensible operation.

It started by installing a clear cache which helped as firefox also hangs when connecting to the internet as a result it goes off-line at random times. Barely ideal. 

Is it worth rolling back to an earlier version that is more stable ? Any other users got debugging suggestions ?

Two days ago firefox stopped working with most of my offices local intranet sites. It either doesnt load at all or loads so slowly its not practical to use. I have refreshed multiple times and that works for about an hour before it goes back to the initial slow behavior. I have uninstalled and reinstalled with no change. I have uninstalled all plugins and addons with the same result. I really do not wish to stop using firefox after so long but I am at the end of my knowledge on how to rectify this . Any suggestions are helpful.

Hello,

since a week or so portal I frequently use - www.wp.pl started to work really slow. It crashes all the time, browser becomes inoperative, closes by itself, etc. It obviously happens to all pages, articles, services related to wp.pl. I cannot open a single page from wp.pl domain without issues. Before it was working completely fine, all of this started to occur for no reason. Also, it happens to wp.pl only. All other pages/portals/platforms function normally. I checked on different browsers - IE, Edge, Chrome and it works fine. I also cleared cache/cookies/browser history in Firefox and this didn't help at all. Therefore there must be something wrong with Firefox browser. Could you please investigate?

Thanks, Jacek

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.

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.

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.

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.

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?
