Hi Mozilla team,

I’d like to report a serious issue with Firefox lately. The browser has been performing very poorly and frequently becomes “Not Responding.” In many cases, websites fail to load properly or get stuck indefinitely, even though my internet connection is working normally.

I’m experiencing these issues on the latest version of Windows 11 with the latest version of Firefox. This has become quite frustrating and significantly affects my daily browsing experience.

I hope the Firefox team can investigate these stability and website-loading issues and provide a fix soon. Firefox used to be much more reliable, but recently the overall experience has been very disappointing.

Thank you.

Not sure the crash report is related to the issue.

The same issue happens to all of my 3 Windows 10 PCs since the update from today.

I have uninstalled Firefox and downloaded again, but same issue happens again.

I cleared the cache also but to no avail

How can I use Firefox again?

Ever since the latest update i've noticed my firefox browser after using it for a while starts eating up all the ram until my computer freezes and needs to restart, i've heard this issue happen to others too but i am wondering if there are any ways to prevent it or will there be any updates to fix it?

I use my firefox on bazzite and have nothing else running in the background, after a while i watch the stats in my task manager and i see firefox using over 10GB of ram and climbing and have to shut it down before it freezes my pc

(can't show any screenshots because if i do then my pc would probably crash when trying to SS it while it has its problem)
