Firefox Community Forum

I’m noticing a strange performance issue with my website: Wildiferemovalpro

On Chrome and Safari, it loads perfectly fine. However, when I try to open it in Firefox, the loading spinner just keeps going, and the "Time to Interactive" feels significantly longer.

I’ve already tried:

Clearing my Firefox cache.

Disabling my extensions.

Checking on different machines.

Is anyone else seeing this? I suspect it might be a script or a specific CSS rendering issue unique to the Gecko engine. Would love it if someone could take a quick look and let me know if they see any red flags in the console.

Describe exactly what isn’t working (e.g., “Videos pause every 5 seconds on Firefox version 118.0.1”).

Include when and where it happens (e.g., which website, device, or operating system).

Mention any steps you’ve already tried (e.g., “I cleared my cache and restarted the browser, but the issue persists”).

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.

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

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.

Why does it take up to an hour for apps like facebook or youtube and others to open after firefox updates. What can I do to fix this? I'm very tempted to delete firefox altogether and will if this issue can't be solved.

I use Yahoo as my homepage and access it through Mozilla. Normally it loads in mere seconds. Last night and today it is taking extremely long to load and in some cases it has timed out. When it does load, all the pictures and other features are not included and either don't load or load much later.

I tried to load Yahoo from MIcrosoft Edge and it loaded perfectly. I am assuming there is an issue with Mozilla?

Thanks for looking into this matter and letting me know.

Hi! I’ve noticed that the site with Slider Revolution installed opens quite slowly in my browser. Do you have any idea what this might be related to? In other browsers, it seems to load just fine. Thanks in advance for your help! Link: https://kasiinod-ee.ee/

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???

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

Hi hi, I just did a complete reset to factory settings of my laptop (MSI), and a wipe of my hard drives too. After reinstalling Firefox (literally the first thing I did after setting up windows), it runs more slowly than before the reset (even for a basic search on Google/Duckduckgo). I am also unable to load any pages under the domain discussions.unity.com : the page loads forever, it's impossible to click on anything (even the hovering styles don't work), and I get a banner at the top of the screen that says "This page is slowing down Firefox. To speed up your browser, stop this page.". Also the memory usage for this page skyrockets (gone up to 4000MB??). I've disabled the 2 extensions I have (Dark Reader and Adblock Plus), restarted Firefox, restarted the computer, cleared the cache, even turned off the mozilla syncing, nothing worked. Any idea on what could be happening here? It's the first time in using Firefox for over 15 years that I've seen this happened.

Thank you for your time and attention <3
