Firefox 3.1 Arrives...Without TraceMonkey

Lora Bentley

The first beta version of Firefox 3.1 is here, but according to The Register's John Leyden, some users are disappointed. The TraceMonkey JavaScript engine, a highly-anticipated feature designed to "improve JavaScript speed by a factor of 40," is not turned on in this version.


Mozilla points out this version of the browser does include enhancements over the previous version: improvements in the Gecko layout engine, better support for CSS 2.1 and CSS 3 properties, a tab-switching shortcut by which users can preview the tab to which they are switching, and improved Smart Location bar control.


Leydon notes that the missing TraceMonkey engine may well show up in later preview versions of Firefox 3.1, since "Mozilla recently decided to release further preview editions." Keep your fingers crossed.

Read somewhere else that TraceMonkey is indeed included with 3.1 beta, but that you have to enable it through about:config . Reply
