Firefox engineers discover a Windows Defender bug that causes high CPU usage
> a ~75% CPU usage reduction was noted when browsing YouTube in Firefox<p>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.<p>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.<p>My takeaway is: prefer independent software as much as you can.
