I came back to Firefox - which was my preferred browser for many years - because Chrome is a big fat memory hog, and would spend quite a while swapping pages into memory if it had been out of focus for a while. Opinions at the time varied widely, but suggested Firefox was more efficient. Nope.. Firefox is at least as bad. And worse; it can't maintain a connection to Gmail which forces me to completely restart the browser every day. Mention this to Mozilla support and all you get from the devs is, "I don't experience this (on my high-end dev system) so it can't exist". Yeah, I'm running Firefox in the 2GB left over on my 8GB laptop - how hard can it be to write efficient code.. memory hog or slightly worse memory hog isn't much of a difference to me. And of course I cant get the extensibility I used to have; and the constant pestering every-single-time the browser gets focus to do an upgrade. Going back to Chrome; though I expect things to get shaken up for the better soon enough (so over this old-skool grind with poorly functional, slow and unreliable software: bring on the AI)
