Firefox Memory Leaks

I really like using Firefox and think it’s a superb browser, but how has it gotten to the 2.x release state while still having incredibly sloppy memory management? Here’s how much memory it was taking at the end of a day with only four tabs open:

176 MB!? Closing it and re-opening it, with those same four tabs displayed, gave me 40 MB. So that’s 136 MB of RAM being used for no good reason. Come on Firefox guys, work on memory management and stability before adding any new gee-whiz features.
