Firefox has surpassed Chrome on Speedometer
Ok, now take the number of years during which Firefox was slower and calculate an averaged value of its speed. This will account for all the frustration it would have caused switching to it in the past. Being faster for 2 days, 2 weeks, 2 months, and probably even for 2 years wouldn't be enough to cause a big change in that averaged value. And that would also measure how much of a guarateed good choice would be switching to Firefox right now. As soon as it will stay faster for enough time to smooth out the differences then I'll start consider using it.<p>I've been a Firefox advocate and user for many years, but then about 6 years ago I had to face the hard truth of how bad it performed with lots of tabs open, and how much of a pain I was causing myself for not switching to a Chromium powered browser.<p>About one month ago, I've checked it out again under the same conditions... and sadly it's still not even close to competitors' memory management.
