Re: Why bother?
I agree, my main browser is Firefox and its RAM hogging has been a disgrace forever.
I find Vivaldi uses much less RAM than either Firefox or Chrome (tally up those per-PID RAM grabs of Chrome's, always instructive). Which is odd, considering Vivaldi's also a Chromium-based browser. Makes one wonder what Chrome uses all that RAM for, if it's not a built-in shortcoming of their engine.
(Disclaimer: was always a bit put off by hardcore Opera fans insisting theirs was the one true way. But Vivaldi's so far delivering rather well)
