Firefox Community Forum

Whenever I have just 1 Window of Firefox and just 1 tab open, task manager ALWAYS shows 14. Why is this? I have refreshed Firefox and lost some of my settings, it did nothing. Have I been hacked and someone else is controlling my browser?

Screenshot shows one firefox with one tab and yet 14 next to it in Task Manager

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

Updated to esr 128.14 Now Reddit (Redgifs) Hosting site for gifs crashes Firefox and cripples my PC. I've tried restarting in safe mode, then refreshing Firefox. Nothing is working. Reddit support just has an issue with the Gifs not playing, but nothing as extreme as what iam experiencing. I believe it may be something is preferences or a codec or something that was changed in the recent update. Any advice/ help would be great. Edit: OS is windows 10 latest updates Amd- Ryzen 7/32gig 3.20 ghz PC. So can handle a little bit of heavy browsing.. FF 128.14 esr Ext- Ublock Origin

Even with Addons disabled still occurs. Really at a loss here.

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала.
