With FireFox 15 lands the fruits of the long running MemShrink project, further reducing memory usage. Gone are the days of bloated FireFox memory footprints. FireFox 15 is stunningly slim in memory. Check out the image comparing FireFox 15 and Chrome 21 running the same workload. FireFox is consuming almost 2/3rds less memory! (And that is with Plugins!)

Opera still uses less. :D

It's great to see Firefox continuing to improve its memory management. Here's the canonical post for those who are interested. But they've been beating on the memory drum for quite a while.

Personally I'll take a faster JS engine over lower memory usage.

Firefox has been and still is my web development browser of choice. I think it's smart that they're focusing on building native web development tools into the browser to continue that proud tradition.

Abelardo, I'd be interested in seeing a memory benchmark comparing Opera, Firefox and Chrome memory usage.

The biggest reason I would take lower memory usage over faster js is getting rid of memory leaks. Even as a memory hog, I shouldn't be having out of memory issues with 16gb of RAM. :)

@Abelardo have you had OOM issues with FireFox recently? I think there is some residual bad taste in peoples mouths about mem leaks from quite a long time ago.

@Jared true, JS performance is of paramount importance these days. But I would make the argument that the delta between memory usage of the two browsers is huge, and the detla between JS performance is small enough to be academic: http://arewefastyet.com/

Also of note, at the link, the Blue line is their new IonMonkey engine, which is moving from Hot Trace JIT to Whole Method JIT (like V8), plus it will be able to utilize their fantastic Type Inference engine, so we should see V8/Crankshaft like performance when it lands. But I've said that before, so we'll see lol.

I'm excited any time a browser takes a big step forward in performance, memory usage or standards compliance. So don't misunderstand me. I applaud the Mozilla development team.

The current browser wars (for lack of a better phrase) are great for users.

I'd like to see additional memory comparisons among the latest browser versions.

The reason I say that I'd rather see JS performance gains over memory improvements is because I think JS performance improvements still have a long way to go.

That said, I don't think the two are mutually exclusive. Each release should and hopefully will improve on both fronts.

Now I'm interested in seeing how IE 10 measures up to Firefox 15. ;)
