> a ~75% CPU usage reduction was noted when browsing YouTube in Firefox

I wonder how many of the people who say "Firefox is significantly slower than chrome" are using windows... On my computer, Firefox IS slower than chrome but (with ad blockers enabled) by an insignificant amount. By still being "the last remaining mostly independent, maintained and reasonably popular browser" I'd prefer it to use over chrome even if it is a bit slower.

Of course, ms is no longer the "old micro$oft" but their history on how they handle competitor browsers makes one think how much interest they could have in investigating and fixing such a bug.

My takeaway is: prefer independent software as much as you can.

Firefox is significantly slower than chrome.

This usually doesn't matter, but you can immediately see it in any page that

A) has a massive DOM

or

B) uses complex regular expressions that eat up the engine

For our benchmark suites at work, Firefox and Chrome generally trade back and forth on who's faster. It's not a consistent 'chrome is fastest'. I'm sure there are specific websites where Chrome dominates but I've yet to see any evidence that we're still in the bad old days where Firefox was orders of magnitude slower on important stuff.
