I love the effort but they have a ways to go: http://imgur.com/aKIqD

I don't use many addons but I do live in long running processes. I hope a memory compactor is in the cards as a milestone in the future.

You really should try running Firefox in safe mode; as others have said, it's not the number of add-ons you're running which is significant, but rather whether any one of them leaks the world.

Alternatively, download an Aurora build, which has our big add-on leak fix.

I appreciate all the work you and all the Mozilla devs are doing. Even if chrome is better(it isn't) I would still use Firefox because of your stance on privacy. I'm on the beta channel now but I will checkout the alpha.

What percentage of the devs are Mac developers at Mozilla? What's the best way to contribute to Firefox for a mac developer with no experience on the Firefox code base? or to put it differently what area needs the most help?

I'm short on time now and typing on my phone but I own Mozilla's Mac OS X code and would be happy to help you get involved. Email me at josh at mozilla dot com.

Tons of Mozilla developers use Macs. IIRC, within the company it's something like 70%. The number is too high really, it would be better if more developers were on Windows.

The one that fixes the Addon leaks is in version 15, which is only in Aurora/Alpha at the moment. It'll be in Beta in July, and released at the end of August.

I switched to it because I was having the same issues as you, and it's made a massive difference.

You can always switch to either beta,alpha or trunk version. They have massive amount of improvements and for me it was more important than a rare(very) instability.

With nearly 200 tabs open, my Firefox is only using 1.5GB, which I find very impressive. This is on linux though, and there are so many conditions that could effect usage, especially across operating systems. The only real problem is it starts to act quite slow with this many tabs. Chrome doesn't have this behaviour, but has a lot more memory usage due to multiple processes.

Odd. I've heard other reports that Chrome falls apart on high numbers of tabs (I'm not sure why that would be.)

There's a decent chance that most of those 200 tabs aren't loaded. If you flip through all of them once, how does it look?

They are definitely all loaded, nearly all of them belong to this session.

Unfortunately one misbehaving extension is enough to break Firefox' memory usage. I ran a fresh profile without any extensions for a few days recently and it was a marvel: Firefox kept releasing all memory immediately once I closed tabs.
