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

everytime I do an update it takes forever for the tabs to load and open....if I did the vpn will my passwords also be saved and top sites be saved as I can not do fire fox top sites so have a different top site

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

I'm having trouble signing into to some online news sites especially videos. The screen shows activity without actually loading a video or website site. I can't connect, it just keeps spinning.

updated to latest firefox 136.0.1 today and several web pages will not load on first attempt. yahoo.com, google along others indicate that page is preventing this site from loading. I have not encountered any issue with Chrome. Have not encountered this issue with firefox previously but very frustrated user. I any attempted to start firefox in debug mode without any extensions or tools and firefox still encountered the same issue. Any recommendation would be appreciated.

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.

There is a gap between firefox and the frame of the window. There is also a inconsistency at the bottom of the browser where it meets the window. Issue persists in safe-mode and all other firefox channels. Albeit, there is no gap or issue with firefox ESR.

Mozilla firefox browser is SOOOOOO SLOOWOWOWWWWW loading and working. Takes literally minutes after clicking open the browser for it to even finally eventually load the tabs - pages. Then it often lags, slows way down. Making it useless for people who value our time and life. 133.03 version. says its current up to date.

Please fix it so it works correctly efficiently.

Hi to all.

when i try to open an https link firefox show only a white page instead of the document from the link.

I make refresh without fix anything I totally remove firefox and delete also the registry entries and after make a new installation without fix anything.

Any suggestion?

Thanks and regards

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

When I try to download anything Firefox Caps my download speed at 10MB/s Other browsers don't. I tried, Edge, Chrome, Etc... they all give me access to my full Gigabit speed. I've attached 2 screenshots with a SpeedTest comparison.

Firefox: 90mbps Edge: 630mbps

Hi, I'm having some issues with Firefox. I'm opening a website (which I usually visit) even slower than with Tor at the same time. I'd love to know why and how to fix it.

For the last few months I've been getting slow responses with online applications. When I switch to chrome, it all runs at a normal pace. Specifically with " The Customer Factor"

I am having a lot of difficulty opening websites ( NYtimes, Washington Post) they takes minutes to open. Sometimes minutes more to open article. ATT says line service is fine. NYT says it service is fine and it works on EDGE Any thoughts?

If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?
