Palemoon under Windows 7: Memory gets fill even after closing most pages

[timofonic]

Hello.

I'm actually using Windows 7 in a temporary way. I usually open TONS of websites and then I close them after reviewing each one. I notied I may will the memory of my system (8GB, considering to upgrade it for tons of reasons) under Windows 7 and and freeing the space even if pages had been deleted, I'm only able to do it by restarting Pale Moon.

Anyone noticed this issue? Are there some way to do a fast test and provide enough details to debug it?

I'm going to reinstall the system in some moments (today as soon as possible, reinstall Windows 7 and install Gentoo), because I need Linux and a clean Windows 7, and put Linux too. I would like to know what's happening and if it's a system error or some weird bug I found (it happens to me).

Kind regards
