Firefox Community Forum

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

• Refreshed Firefox
• Created a new profile
• Uninstalled Firefox leaving my old profile
• Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

DISTRIB_ID=Ubuntu DISTRIB_RELEASE=20.04 DISTRIB_CODENAME=focal DISTRIB_DESCRIPTION="Ubuntu 20.04.6 LTS"

Firefox 150.0.2 (64-bit)

After rebooting my computer, Firefox hangs for a very long time trying to access common websites such as cnn.com, facebook.com, mozilla.org and apnews.com. A google search will work, but the links (including the google control links at the top such "AI Mode All ... More Tools" are not active. Often there is a message at the botton of the screen indicating some external site is being accessed. During this time, other sites that do not have external references will quickly open in other tabs (bwi.com is a good example). After about 20 minutes, everything magically starts working correctly. Disabling "secure DNS" does not correct this problem.

I use both Firefox and Chrome with 2 separate EBay accounts so I don't to keep switching logins.

Firefox is very SLOW TO LOAD my EBay pages (like 10-15seconds). Chrome is almost instant.

Can you try and load an EBay page logged in as a seller and see WHY there is such a lag in loading.

I'm using a state of the art Win 11 Alienware machine on a 1 Gig internet. I've tried switching which account I log into and it's the same. So it's NOT the computer, the internet connection or the individual account.

Thanks!

Windows11，firefox版本149.0，增强型跟踪保护设置为标准，基于 HTTPS 的 DNS”启用策略为默认保护，扩展全关。在我打开www.douyin.com的标签页时，通常要加载5秒钟甚至10秒钟，视频才会播放（如图）。作为对比，我在edge浏览器上登陆了同一个抖音账号，打开同样的书签页面，edge并未出现明显加载画面，在chrome上打开未登陆的抖音标签页也未出现明显加载画面。这个情况也许是从近期firefox自动更新后出现的？请问如何解决

I refreshed the browser, I switched off all of the extensions; makes no difference. If I switch adblock plus back on, it doesn't block ads. Everything is super slow. It takes forever for some pages to load. I had no problems before the most recent update.

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?

I am having issues where pages I open will show it continuously opening (Page load status on tab keeps bouncing even when page is loaded) some page I need to try a couple times to load content. This seems to have started when I upgraded my Mac to OS 2.6. Currently I do not have any extensions or themes to troubleshoot. I did try in troubleshooting mode and everything worked fine, but all the documentation points to themes. I have tried clearing cache, quitting, restarting my computer it always comes back. Is there anything I can do to stop this otherwise all my work on Firefox will have to be moved elsewhere. Below the guess about my OS it says my OS is 10.15 which is incorrect it is Tahoe 26.3. I am not sure why this would come up as a 2019 OS.

Best,

Long Delay occurs loading multiple websites, from facebook to other sites and I often get a delay of over 20 seconds with any site involving a CDN connection of various types. I am using W11, latest version of Firefox. 148.0 (Says latest version)

When it happens I can see the connection url in the bottom left hand corner includes a CDN part. Settings are Proxy settings "Use system proxy settings"

• DNS over HTTPS is set to "default protection"
• IPv6: ISP is has just changed from gigaclear fibre to toob fibre, but it has made no difference.
• Have cleared cache. No change

This is very frustrating. Started a couple of months ago. I have ended up using Chrome ratherthan Firefox and I am close to giving up with firefox. Help appreciated.

Hi, on my macbookpro. Searches take minutes to load, websites take minutes to load. Youtube takes minutes to loand, but once loaded and I start a video, it runs for a couple of minutes then video suddenly stops and I have to wait for couple of minutes for the video to continue again and it keeps repeating, all my other web browsers (Safari, Chrome, etc..) works perfectly. It also uses sFirefox is bascially unusable! I am running the latest version.

I also saw a NoScript XSS Warning:

NoScript detected a potential Cross-Site Scripting attack

from https://www.youtube.com to https://accounts.google.com.

Suspicious data:

Error: Timeout! DOS attack attempt?,(URL) https://accounts.google.com/ServiceLogin?service=youtube&uilel=3&passive=true&continue=https://www.youtube.com/signin?action_handle_signin=true&app=desktop&hl=en&next=%2Fsignin_passive&feature=passive&hl=en

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.

The server at iso.scanfor.scanfor.be is taking too long to respond. iso.scanfor.scanfor.be is an unsecure (http) INTRANET site not publicly acessible (local server). At same time other browsers are perfectly able to access the site! So there is NO connection issue... This problem happens mostly in the morning, and solves itself during the course of the day  :)

Anyone any idea where to look for an issue???

For the past few days, DDG search has been slow. I'm using Firefox version 146.0.1 on Windows 11. Disabling extensions didn't help, but clearing the cache had an effect: The first search after clearing cache is fast (about 1 second), but subsequent searches are slow (about 15 seconds). I was able to repeat this sequence several times. I also cleared cookies, but that didn't seem to have any effect. DDG Search works fine in a Private window. I'm stumped!

Hi, I've noticed that web pages load slower recently. As all of the recent updates seem to be about adding AI features to the browser, I can only assume that this is the problem. I have disabled the .ml. settings and saw an improvement in performance, but performance is still degrading over time as new updates release, so I'm guessing that I missed something in the settings.

I'm also concerned about privacy. As these AI features make use of tools that cannot always be run completely locally, it increases vulnerability to provide very little value, if any at all. I would argue that it makes the browser worse rather than better, so that's not worth any level of risk to me.

If these features continue to be expanded then I will look for an alternative browser. I know that it is tough to find browsers which aren't Chromium-based these days, but it's not impossible. Firefox is not the only choice.
