After running Firefox for quite some time, I see the following in about:memory.

Out of these, 84Mb are unused memory, which looks a bit weird. Might be related to bug 894993? Ben, does behavior this look familiar to you?
Flags: needinfo?(bent.mozilla)
Johnny, is this nightly? And does a manual 'Minimize Memory' bring the number back down?
Flags: needinfo?(bent.mozilla)
Yes, this is nightly from probably a couple of weeks back, and yes, minimize memory usage does get rid of ~89 of the 90 megs used.
Hm, a couple weeks back... Before bug 894993 landed?
Hmm, likely... I'll update my build and keep an eye on this.
Let's be optimistic and assume this is fixed... jst, please reopen if you see it again.
