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.

I’m experiencing an issue in Firefox where a web-based application loads the main interface, but the interactive content does not appear or remains blank. This happens consistently when the site is accessed through a CDN, while direct access to the origin server works correctly.

The issue seems related to delayed or timing-out requests (similar to a 524 timeout), where dynamic content fails to load within expected response times. Static elements render properly, but anything requiring API or server-side processing does not display.

This behavior also affects browser-based puzzle apps like Spelling Bee, where the gameplay area may freeze or fail to load entirely in Firefox. I’ve tested across multiple networks and devices, and the issue persists only in this routing setup.

Has anyone experienced similar rendering or loading issues in Firefox related to CDN timeouts or delayed responses? Any troubleshooting tips or Firefox-specific settings that could help would be appreciated.

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,

Gina

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.

the app just asked me if i my experience was good and this is where the link brought me. The firefox mobile app on android is performing teribly over last few updates. websites take 1000x times longer to load some elements. it feels like the cache gets full after loading 10 images. youtube videos take nearly 30 seconds to load on gigabit internet. marketplaces just wont load images. it gets stuck buffereing images and videos. the easiest fix is to switch browsers which completely eliminates issues. this is happening on multiple android devices. either the code for this app is ruined or compromized. the problem is not on my linux or mac devices. I really have loved firefox up to this point, and its sad that after 1 month of questionable management the browser is starting to break down. i am now forced to switch just so i can use the internet. also side not if there was ever a way to get themes on mobile browser that would be nice.

Hello everyone,

While testing some fan-made game community websites, I noticed that Firefox handles them a bit differently compared to Chrome or Edge. For example, I checked https://nullsbrawl.tech/ (not an official site, just a community project) and saw that it loads more slowly and sometimes behaves differently in Firefox.

This made me curious:

Does Firefox have different handling for script-heavy or unofficial community websites?

What tools in Firefox Developer Tools would you recommend for debugging performance issues?

Are there guidelines for developers to make such sites more compatible with Firefox?

I’d love to understand more about how Firefox manages these situations.

Thanks in advance for your help!

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:

I tried it, it loads through EDGE, but through yours, if I enter it into the search, it loads at 70%, but the page still seems to work, albeit slowly. I didn’t have such problems with EDGE
