I’m not tech savvy but Firefox just won’t respond I struggle to get a page to load and sometimes I get empty pages behind each other but don’t know how I get rid of them

I'm having an issue where when you try to do things in-browser, Firefox freezes, puts up a grey screen and holds this way for a few seconds. Scrolling and video seem to trigger it most often. Repeatability is nominal; sometimes I have no problem, sometimes every action I try to take results in another fit of grey screens and freezing.

I'm using version 153.0.3 64bit on Windows 10.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

Whenever I have to restart my cpu, the menu bar appears to try to open all of the tabs and it causes system hangups and says that Mozilla Firefox is not responding. What causes this ??

Hello! Since the latest update to Firefox (153, I believe) my Firefox has not worked. It starts up perfectly fine, but quickly freezes, becomes non-responsive, and needs to be closed. No matter how many times I attempt to open it, the same thing occurs. There’s been been occasions where it hasn’t frozen immediately so I have been able to turn off hardware acceleration as well as remove my theme and disable all my add-ons/extensions, but this has done nothing. Creating a new profile does not help, nor does trying Safe Mode: the same thing happens no matter what. I tried to reinstall the update, but this also did nothing. I haven’t yet tried to uninstall & reinstall or do a Firefox refresh as those are my last resorts and I won’t do them unless I’m sure they’ll make a difference. I haven’t downloaded any new extensions recently, and this only started happening after the most recent update. I’m not sure what else I can try at this point, and am very frustrated.

On a new laptop with Win11 Home (x86-64) with Firefox just installed, the cache size is 54 MB. When Privacy and Security -> Clear Browsing Data is clicked, Firefox hangs - no input is accepted and nothing appears to be happening. On closing Firefox and then reopening the cache size is reduced and Clear Browsing Data operates as expected.

Why is the cache size (54 MB) so large? Why does Clear Browsing Data hang Firefox?

Hello, After the last update i keep seeing a blank page when i open a new tab or new page. i tried the troubleshooting mode but the same. i need to refresh every time i open a new page.

I have tried safe mode. No joy, but it has shown plain vanilla FF is the issue, not extensions.

(I'm using a different browser to make this report, so Share Data button is of no use here.)

Watching any Bilibili live stream causes severe performance issues. The main problems I can observe are intermittent severe mouse cursor stuttering/frame drops or the cursor becoming unresponsive, accompanied by the taskbar process (explorer.exe) intermittently restarting.

I have tried disabling the Picture-in-Picture feature and tampermonkey add-on, modifying the Windows 11 registry to turn off MPO (Multiplane Overlay), adjusting browser hardware acceleration, and tweaking related settings in about:config, but none of these have been able to prevent the issue.

Hello everyone,

I've recently noticed that Firefox has become slower than usual. Some websites take a long time to load, and occasionally the browser feels unresponsive even though my internet connection seems to be working fine. I've already tried restarting Firefox and clearing the cache, but the issue still occurs.

Has anyone experienced something similar or found a solution that improved Firefox's performance? Any suggestions would be appreciated.

Thank you!
