My browser worked fine until a few weeks ago. It then slowed considerably in serving pages. Instead of a few seconds, it would take 30 seconds. It has done this consistently since then. I don't recall installing new extensions. My other browsers work normally at normal page speed. The Windows OS seems to work fine as well.

Can anyone think what might be causing this & how to fix it?

Going to ANY website, it takes "forever" to load, but after loading normal speed is experienced. One way to get a website to initially load more quickly is to click the "X" which the spinner is going endlessly, then refresh the page, whereupon it will usually load instantly.

The problem is experienced with any and every website. This problem does not occur with Chrome or Edge:

Windows 11, Firefox 142.0.1 64 bit.

My computer is running very slowly on Firefox. It takes forever to load anything on Facebook, or my Bank, or any other site where I want to use Firefox. I have DuckDuckGo for search, and that is really slow, too. So I thought that maybe Firefox needs to be updated. But I don't know where to find the Menu Bar. I am 80 years old and don't know the computer "jargon." By coming here I lost your step-by-step directions about what to do AFTER I find the Menu!

Hi there,

I have a remote job that requires me to swiftly do online searches and send emails. Firefox is my preferred browser, but sadly I notice that it tends to sometimes be slow in loading pages. Any ideas for how I can improve it, or how Firefox can improve its performance on my machine? Here's info to help you troubleshoot:

--I always download the most recent Firefox updates when prompted. --My machine is a Lenovo with a lot of memory running on Windows 11 (I think), so the machine itself runs really fast on other browsers, such as Google Chrome. --Firefox seems to be slowest in the afternoon, which puzzled me. --I'm connected to the internet via high-speed cable, not slow WiFi.

Thank you for any help you can provide!

My home page is Fox News and Firefox current version is slow opening videos everywhere, but especially on Fox. Any ideas? They open quicker on other browsers but I like Firefox!!!

running version 142.0.1 on windows 10 on a pc. With the latest three updates of firefox, facebook is the only site that loads very slowly. No problem on a pad or cell phone using the same isp and mozilla. What happened?.

I have started to delay Firefox updates as much as possible. Takes hours to get things back to normal, i.e. it appears to be done and installed, but access to say Google just clocks and clocks and clocks. Hence, I've avoided updates as much as possible.

Firefox Support Team, Hello I am a Firefox user in mainland China. I'm experiencing slow webpage opening (all webpages) with Firefox, and the problem persists after disabling the doh setting on Firefox as described on Firefox support. So I tried to change the doh settings on the OS (my OS is Windows 11, which supports doh settings on the OS), when I tried to use only the doh provider (Alidns) in mainland China, Firefox could open web pages very fast, but after I added the doh provider Opendns) outside of mainland China. Firefox becomes very slow in loading web pages. This problem only occurs in Firefox, not in chrome or edge (I currently use both Alidns and Opendns, Alidns as first choice and Opendns as backup).

So I would like to ask if Firefox has a logic that determines the priority of dns usage, prioritizing one of the dns providers when there are more than one at the same time. If so, can I change this logic. Because using dns services from other regions in mainland China will encounter problems such as very high network latency, packet loss, etc., I set up different regional dns providers at the same time as a backup, and I mainly use the mainland China dns provider.

My temporary solution for now is to actively enable doh service on Firefox and customize Alidns as the service provider. This gets Firefox working, but I think it adds complexity. Best regards, someone

The above is machine translation, the original Chinese text is as follows: 火狐支持团队，你好 我是中国大陆的火狐浏览器用户。我在使用火狐浏览器时遇到了网页打开缓慢的问题（所有网页），根据火狐支持上的描述关闭火狐上的doh设置后问题依旧。于是我尝试更改了操作系统上的doh设置（我的操作系统是Windows11，支持在操作系统上设置doh），当我尝试仅使用中国大陆的doh提供商（alidns）时，火狐可以很快的打开网页，但我加入中国大陆之外的doh提供商（opendns）后。火狐加载网页就会变得非常慢。这个问题仅在火狐浏览器出现，在chrome和edge上不会出现（我当前同时使用alidns和opendns，alidns作为首选，opendns作为备用）。

所以我想询问火狐浏览器是否有判断dns使用优先级的逻辑，在同时有多个dns提供商时优先使用其中某一个。如果有，我能否更改这个逻辑。因为在中国大陆使用其他地区的dns服务会遇到网络延迟很高、丢包等问题，我同时设置不同地区的dns提供商是为了备用，主要使用的是中国大陆的dns提供商。

目前我的临时解决办法是主动开启火狐上的doh服务，并自定义alidns为服务提供商。这样能使火狐正常工作，但我认为这样增加了复杂性。 谨致问候, someone

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?

like the title says, usually at least once a day firefox will just stop loading web pages entirely. more specifically, it gets stuck loading any page infinitely. occasionally if i wait long enough things will start loading again, but usually that time never comes and i have to restart the browser. i'm kind of a tab hoarder so restarting the browser can be annoying in itself, since i have to wait for the browser to load. i'm not really sure how to troubleshoot this with extensions and the like since i haven't noticed any trend in when the problem occurs. weirdly enough, it happened while i was typing this and while every other website fails to load, the mozilla support site is consistently fine. any ideas or suggestions would be greatly appreciated.

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.
