Hi everyone,

I’m facing an issue with Firefox where some quiz websites are not working properly. Pages either load very slowly or sometimes don’t load at all. I mainly use these sites daily, so it’s affecting my routine.

For example, when I try to open this quiz page: http://telequiz.pk/

Sometimes it works fine, but other times it gets stuck or shows incomplete content. I have already tried refreshing the page and clearing cache, but the problem still happens randomly.

Can anyone guide me on what could be causing this? Is it a browser setting, extension conflict, or something else? Also, what steps should I follow to fix it permanently?

Thanks in advance for your help

Firefox 152.0.4 64bit Windows 10.

This website still loads, but the live radar stopped working this morning, don't recall any updates coming in to cause any changes, what gives?...

Hi everyone,

I’m running into a performance issue specifically on Firefox that I can't replicate in Chromium browsers.

On my site https://snippingtoolshortcuts.com/, the layout and text load fine, but the scrolling performance feels "heavy" or jittery on Firefox (Version 133+). When I test the same page in Chrome or Edge, the smooth-scrolling and hover effects on the shortcut tables are perfectly fluid.

I’ve tried:

Testing in Troubleshoot Mode (Add-ons disabled).

Disabling hardware acceleration.

Checking the "Network" tab for slow-loading scripts (everything seems green).

Are there known issues with Firefox's handling of large CSS tables or specific grid layouts that might cause this? I'd appreciate if someone could check the URL on their end to see if it’s a global rendering issue or just something with my local profile.

Thank you.

With respect to problem of latest FF update interfering with spell check on outlook mail, am i okay to assume that FF will fix this problem soon and just wait until they do that? There has been suggested a work-around remedy but since i am computer-challenge i prefer to wait and let FF do Its Job as it has done so wonderfully in past as i have used it for decades.

I encontered one issue while I browsing one page the firefox browser will automatically logout but another browser like Edge will not. and if I use the firefox browser in trouble shooting mode it also will not logout automatically. I've stored the developing tools logs for you to analyse.

I hope this is ok to post here.

My windows MSN app says this. When I select '"Open in Browser", this happens.

However, when I select "Video Hub", it works normally.

I tried clearing the cache and cookies. Reset. Uninstalled/reinstalled. I can separately access the website on Firefox.

I recently noticed a scenario where a web tool loads updated data (via JavaScript and backend API), but the browser (and proxy cache) still serves outdated content when viewed on a different device. Clearing the browser cache fixes it, but that’s not a scalable solution for users.

I’m curious: does Firefox’s caching behavior differ for pages that use heavy client-side updates (e.g., incremental score calculators) compared to standard static pages? Should we be explicitly sending cache-control headers like no-store or must-revalidate to prevent stale data?

Any documented guidance on how Firefox handles cache revalidation for dynamic web-apps would be helpful.

Thanks in advance for any pointers.
