Re: Yaya yada yada
I've not looked at how much memory Firefox uses in a while (but it has got a lot better in the last five years), so, a quick test:
Firefox, with ten tabs open: 755Mb
Chrome, with the same tabs: 54Mb, wait a minute?!
Ah, so Chrome opens separate processes, so adding up all it's memory: 785Mb
Both Firefox and Chrome are running Lastpass and uBlock Origin, Firefox also has a couple of other addons.
Just for lulz:
Edge, no plugins (also split into processes): 1207Mb
Internet Explorer: 1107Mb
So Firefox is the most memory efficient browser on my computer today, and Microsoft have a lot to be ashamed of (although adblocking might have had a hand in those results)
