Mozilla has been working on improving Firefox's memory performance lately. Some of the improvements should already be visible in the latest Firefox 7 stable release, but testing releases, Firefox 8 and Firefox 9 move things even further along.

But Mozilla is not done yet, is is now working on slimming down its JavaScript engine, SpiderMonkey, and has made some rather big changes to come in Firefox 10 and Firefox 11.

As Mozilla notes, SpiderMonkey is being put on a diet. Its inner-workings are being rewritten and redesigned to take up as little space as possible.

Mozilla developer Nicholas Nethercote has all the details on it, but, unless you're a developer too, it's not exactly light reading.

Suffice to say, Mozilla is leaving no stone unturned. Some of the changes have been implemented, but many are in the works while some are just theoretical at this point.

One thing that is more concrete though is that TraceMonkey is being deprecated and is being removed gradually. As of Firefox 9, which introduced type inference, TraceMonkey was disabled for web content.

I am glad that they are going to fix this. Firefox does use alot of memory. If they fix this alot of people would be happy with this. Nice find ;)

Always good to know they are working on lowering the memory usage.
I am not bothered at all with the current usage considering I have more then enough memory.
Good on you Mozilla.

99,9% of the Firefox user have more than enough memory and in the real world I haven't heard anyone complaining on the resource usage......and this is the second time Mozilla is announcing a 'MAJOR' memory tweak..... I;m starting to think that Mozilla has run out of ideas on how to improve Firefox and now they are just improvising OR they are looking for a free way to advertise themselves.... :dodgy:

The main issue for Firefox for me at least isn't the amount of RAM it uses, but the amount of times it freezes unexpectedly, even without any add-ons. Lower memory footprint is always a good thing though. I don't think I will be moving back to Firefox any time soon however.

I think the best thing about Firefox is the absolute clarity of the dev team. They show you exactly what they're doing and what their plans are.
