I only had two tabs open, one which was Google homepage, the other was my webmail via Juno ... The max memory consumption during my 8 hours of continued use was no more than 33mb, which is great. I went to bed, and when I got up, I came to see that Firefox memory consumption had jumped from 33mb, to more than 337mb in memory usage, simply when I was sleeping and no activity was going on my pc at that time. 

Reproducible: Didn't try

Steps to Reproduce:
Haven't tried to reproduce yet, but will update this tomorrow if I get the same problem overnight..

I have no extensions other than what's the default DOM 1.9b2, and default Firefox theme.. I have a few snaphots of task manager to show how the memory use is not only excessive, but continues to grow even when Firefox is currently idle.

As you can see (if my images go through) the memory climbs from 301mb, to 337mb in around 30 seconds...
