Mozilla Is Working On A New Javascript Engine

Filed under: — By Aviran Mordo @ 4:42 am

Mozilla is brewing a new extension to the Firefox JavaScript engine, hoping to fix a flaw in its setup that occasionally sends the open source browser back to 2007.

Dubbed JaegerMonkey, the new extension will operate alongside the much-ballyhooed TraceMonkey - an extension that debuted with Firefox 3.5 in June of last year - interpreting JavaScript code unsuited to “tracing.” With Mozilla’s current setup, code that can’t be optimized with TraceMonkey is kicked back to an aging interpreter that runs JavaScript at speeds reminiscent of the dark ages before Firefox 3.5 or Google Chrome.

The JaegerMonkey project is only about two months old - and it’s a ways from testing in a Firefox beta build - but a blog post from Mozilla programmer David Anderson says it’s already providing a 30 per cent performance boost over that old interpreter on x86 machines.
