True Firefox, forks of Firefox before the dropping of XUL and before the switch to multi-process, can do 300 tabs in less than 2GB of ram. It's just the chrome-a-like modern firefox that, like all multi-process browsers, is a ram hog.

Dramatically improved application security and performance at the cost of cheap hardware, which for most people gets significant upgrades every few years on desktop and every couple years on mobile, seems like a good trade to me.

Yeah, for most people new Firefox or Chrome is a no brainer. They don't need a browser that can surf the web. They need a fast javascript engine to run a few tabs of applications that just happen to be delivered over HTTPS.

People like me that just want to web surf can disable JS by default and then single process mode -JS is infinitely more secure than a multi-process +JS. Just different use cases.
