Why are there 61 Firefox folders in Task Manager?

Hello,

First, go to Firefox, then press Shift + Esc, then it will open a window showing each subprocess and which one is eating the most RAM. If it is a tab, then you can just close it to instantly free up more RAM.

Next, go to about:memory, and click the "Minimize memory usage" button, which will make Firefox, minimize memory.

After that, to reduce Firefox's RAM footprint even more, disable any outdated/faulty extensions, as they can be a major source of memory consumption. Next, go to menu>settings>performance, uncheck "Use recommended performance settings" and check "Use hardware acceleration when available". After that, restart Firefox.

Next, if you keep a lot of tabs open, try closing some or getting an extension to put them to sleep, which frees up the ram from that website.

Thanks so much for the info! A little tied up at the moment but will give it a try shortly. My task manager shows me each sub-process. Is that what you were referring to at the start of your reply?
