Firefox 11 and Thunderbird 11 released

The fact that this bug has been there for so long, though, makes me wonder if only us 64-bit users are affected, and that that's why they're sticking with 32-bit by default.

Also, the 64-bit builds probably chew a ton more memory. I keep a metric ton of tabs open, and my Firefox session hovers around 2GB RSS. (It was up over 3GB before I gave it a "hygienic reboot." Also, I found that ad-blocking https://www.facebook.com/plugins/like.php saves a couple hundred megabytes all by itself.) Much of that 2GB is consumed by various Javascript-related stuff according to about:memory, and I imagine that's all very pointer intensive.

Given Firefox's laser focus on memory footprint, I imagine that also pushes them to defaulting everyone to 32-bit builds. Unfortunately for me, they don't seem to work "out of the box" for me on my 64-bit system, so I have to go hunting at the FTP site as linked above.

(I'd be happy if we could have a "small" memory model with 32-bit pointers, along the lines of this -- https://sites.google.com/site/x32abi/ -- as long as I could also still run true full 64-bit apps when needed. That seems like a good compromise to put pointer-heavy programs on a diet while still taking advantage of x86-64's other features.)
