Hello,i got windows Windows 10 Pro 22H2 and latest mozilla version,just noticed my total ram usage with mozilla launched is up to 12gb. After closing the browser im getting around 10gb ram usage. After restaring my computer im getting 3.5gb ram usage totally without mozilla started. After i start to use mozilla,my ram usage increases up to 12gb,sometimes higher,again if i close it totally,im not getting 3.5gb ram usage BACK for some reason,only a couple of gigabytes (same gigabytes resource monitor shows for mozilla),so Mozilla continue to use loads of ram and i dont see it uses someting in the monitor. So i need to restart my computer each time i close Mozilla if i want to have normal ram usage,thats awful. Screens are included. Regards

One more pic,mozilla shows it uses only 2gb of ram. Though really it uses a few times more...

Does it still happen if you disable hardware acceleration?

Seems turning off extensions solved the problem. Could they cause it?

Can you narrow it down to one extension in particular?
