“Not sure why people still use Firefox.”
Addons. Here’s the ones I use to increase my productivity by a couple of orders of magnitude: adblock plus, betterprivacy, classic theme restorer, cookieculler, element hiding helper for adblock plus, ie view, findbar tweak, flash video download helper, refcontrol, roboform, tab mix plus, visited, et al.
Differences in browser speed are pretty much irrelevant anyway when one has REALLY high speed ISP, lots of RAM, and a solid state hard drive.
Nice list - Thanks!
