Firefox 9 Released, JavaScript Performance Greatly Improved

MrSeb writes "Firefox 9 is now available — but unlike its previous rapid release forebears where not a lot changed, a huge feature has landed with the new version: the JavaScript engine now has type inference enabled. This simple switch has resulted in a 20-30% JS execution speed increase (PDF), putting JaegerMonkey back in line with Chrome's V8 engine, and even pulling ahead in some cases. If you switched away from Firefox to IE or Chrome for improved JS performance, now is probably the time to give Firefox another shot."

Firefox - Too little, too late?
Too little: Doesn't sound like it, given the writeup of this release.
Too late: An install of pretty much any software is one click away. No software is too late - a later version can fix the problems of earlier versions. Most users don't have any problems with memory usage, don't care about how the footprint compares with this or that version of chrome etc.

it completely abandons geeky stuff like NoScript or Adblock

Oh boy, now I can enjoy adverts featuring rotten teeth and modal popups that insist I "like" them on Facebook again!

Seriously, if I wanted to put up with this crap I'd go back to using IE.

This is why I love Tree Style Tabs. You get the tab bar on the left (or wherever else you like it), tabs structured hierarchically, collapsible trees and all that fancy stuff, including vertical screen estate.
