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.

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.

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?

Добрый день. Сегодня обновился у меня браузер до последней версии и перестал нормально открывать странички сайтов открывает и через время зависает почините пожалуйста скрин смотрите вот так все зависает и не отвисает

Was using computer and was interrupted by Firefox update. Got the "See What's New" window, closed it to have Firefox open in the new tab. Won't open, tried three times got nit responding each time. Shut down computer, started over. Booted up abd Firefox partially opened and now, again, not responding. When I close it reports to Microsoft. Try to open again, same result.

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.
