No no, Firefox doesn't need 10Gb, it is much less as this test here shows, much the same is required for all of the top three browsers, with Edge just a fraction less than both Firefox and Chrome.
Yes it does !

I don't know about tests and other browsers. The only test that's worth something as far as I am concerned, is using FF on my machine, for many years now, and seeing what happens. It happens that it can takes 10GB no problem, with only 60 tabs and 3 windows opened and just a few weeks or months running !

I did notice though that it depends heavily on how many tabs are open and what's in them. The biggest memory hog seems to be Youtube pages. I tend to have lots of YT videos/pages open, and I noticed that FF roughly uses 100MB or so of memory for each and everyone of them ! I don't know if it's FF or the crappy "Flash" plugins that it uses to read the videos, but it doens't matter sin one does not go without the other...
So to try to stay out of trouble, avoid running out of RAM and swap and having the computer freeze on me.... I try to discipline myself and not open too many tabs. Also, restarting FF after a few weeks helps a bit, I guess it clears some junk from memory.
Right now it pretty reasonable. Takes "only" 3.8GB spread over 9 different threads, for 22 open tabs including 5 Youtube pages.
Can't fight that, it's just the way it is. I hate it. I don't find it acceptable technically, but that's how it is so... unless I keep restricting myself to a small number of tabs, which I can't do, then the only option is to give FF what it wants : lots of GB of RAM, and unfortunately for me that means a brand new machine as it's 15 years old/obsolete so I can't upgrade any individual component, the entire thing needs to be replaced.
I am not crying, 15 years is pretty good life expectancy, much better than an Ipad or fancy modern Smarthphone !

HP Laserjet 6P at 24 years now and still going strong !! I am sure it can manage 30 years, let's see !

Regardless, think I would buy a new printer. Would like a colour printer ! .... but no inket jet. A decent A4 laser colour, SOHO type, not the crappy consumer style built to a price with proprietary language, that fall apart after 6 months and small capacity toners that do very little pages and cost an arm per page.
Needs to be Linux friendly too, or else I cant use it.
I find it's still too expensive for me.. also would like an old / affordable A3 B&W printer, or better yet a little tracer, so I can print fold out schematics from service manuals, when I need to trouble shoot some my old Tek scoep typically...
