推荐一有趣的扩展：Leak Monitor

https://addons.mozilla.org/firefox/2490/

Firefox extension Leak Monitor keeps an eye out for memory leaks in Firefox, alerting you each time an extension has sprung a leak.

Although Leak Monitor is geared toward developers, it's not too difficult to wade through the leak alert and find out what extensions are causing the most problems; for example, I was surprised to find that my Adblock extension seemed to have a pretty steady memory leak. You probably won't want to leave the Leak Monitor running all the time, but it's a good way to hunt down a leaky extension if, like me, you find your Firefox memory usage has somehow crept up to 500MB in the course of a day and you suspect that an extension or two might be at fault.

ps：but... who will monitor the leak monitor?

这个不错，好用的话就不需要用Memtriage了

Hmm... nice tool. Should be pretty useful.

我只有两个扩展，非此即彼

这个扩展一般是用做测试用的 开发扩展的时候可能需要测试是否这些代码会导致内存泄漏 我们用的不多把
