Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

since the uptate to version 144.0.2 I have two problems. the first one is async streaming on platforms eg. youtube or netflix. The videos take a very long time to load. Even if a video has already preloaded and I skip to that area, the video takes an extremely long time to load again. The 2nd problem i have in livestreams eg. live-TV or twitch. The loading time is very long. It is so long that many livestreams are doesn't even able to start. So, it is no longer possible for me to watch livestreams on Firefox. what i've done to fix it: - I deactivated all Add-on's and deleted all browser Data - I made a new profile and deleted the old ones - I reinstalled Firefox

Nothing worked. so pls can you help me that I can use Firefox normally as usual? (sorry for my bad english, I'm from Germany)

Trying to browse ebay using Firefox. The pages have become really slow when loading.When scrolling down the page is blank then slowly populates as I scroll down the page. I've just tried microsoft edge and there is no problem.

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

Since the 145.0.2 update web pages are loading very sloooooooow. Also, images are loading very slowly, if they load at all. At the start pages would not load at all then about a week they started loading but very slow as mentioned. Any ideas/help will be very much appreciated. I am using Windows 11.

Since the last Firefox update, normally used web pages load very slowly or time out. When clicking on a bookmark the page loads very slow so I stop the page from loading and hit refresh and it loads almost instantly like it normally used to do. Any fixes available? Thank you, Dan.

Ok, this is a weird one.

I can't load https://duckduckgo.com. It breaks search in a new tab, but I also can't visit it directly from the url. The tab simply does not load.

I've cleared cache, cookies, and extensions. I've refreshed Firefox more than once.

I can visit https://html.duckduckgo.com. I can visit https://lite.duckduckgo.com.

However! In a private window, I can visit https://duckduckgo.com It still breaks in a secondary normal window.

No other site appears to be broken.

My network is pretty fast -

• Download Speed - 76.30 mbps
• Upload Speed - 113.13 mbps
• Idle Latency - 61 ms
• Download Latency - 59 ms
• Upload Latency - 18 ms

Even though this is a pretty fast network connection, my websites on firefox take a long time to load, for example youtube takes like 2 seconds to load, and sometimes some elements of the website do not even load. This is a very annoying problem which I would like a solution for.

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Recently I’ve had a few Firefox problems on my W11 desktop. Sometimes when I try to load a website, nothing appears until several seconds (30 or more) have passed. During that time, the bottom of the screen shows the message Transferring data. Then, after that long wait, very often only a top piece (1/3 to ½) of the page appears. If I wait long enough (a minute or two), the rest of the page appears. Another problem is illustrated in the two images. When I go to AARP, I get the first image. T then press the Reload button and the second image appears. This problem is fairly recent. Previously, the first image always loaded with not problem. Any ideas of what’s happening and, even more importantly, how it can be fixed? Thanks.

Firefox stops loading pages. I try to browse a webpage and it just keeps loading, but nothing happens (black screen). I open chrome, request the same webpage, it loads immediately. In Firefox, it keeps loading. Sometimes it loads it after 1-2 minutes. Sometimes not. Problem is fixed after restarting firefox, but comes back again after some time.

I use nyt.com to assess my account with Firefox. lately, it has been very slow to load and when i click on an article, it is very slow to load.

I find that my desktop browser firefox is very slow or doesn't work at all on a lot of websites like amazon or fortnine.

My internet connection and computer are not the issue: 270Mbps (wired connection) Processor AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz) Installed RAM 32.0 GB (31.1 GB usable) Graphics card NVIDIA GeForce RTX 4070 Ti SUPER (16 GB) Storage 3.58 TB of 10.92 TB used System type 64-bit operating system, x64-based processor (Windows 11)

My old PC and my mobile phone runs these website fine.

Sometimes the website will work for a moment, but stop and just load for ever after I open a new tab or clink a link. My task manager doesn't show any ethernet usage despite the tabs indicating they are trying to load. Refreshing the tabs does nothing and no matter how long I leave them they don't load. All my drivers, OS and programs are up to date. I have disabled my enhanced tracking protection and I don't have any adblockers. I have tried using the CMD "ipconfig -renew" and using ccleaner to clear out my cookies and cache but, nothing seems to have any lasting effect.

I am losing my mind trying to fix this. Why can I not browse the internet on my PC?

Any help on this would be amazing and much appreciated.

Sincerely, Calvin

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I have tried several online suggestions to speed up page load on my Firefox browser. None have improved my situation. I can start a web page load on Firefox while simultaneously working from another browser. The other browsers load and I am able to complete my business before Firefox even loads. I am quite frustrated by this as I have used Firefox for as long as I can remember.

I am using Windows 11

Duck duck search via Firefox has become painfully slow, although if Google search is used the speed is OK. I have cleared caches, cookies etc without any improvement. Firefox 148.0.2, Windows10. Is this a recognised current problem?
