I found this thread because I am also experiencing memory issues when visiting Facebook and some other sites (LinkedIn.com is another) with Firefox 3.5 on Ubuntu 9.04.
Facebook is overall very slow, but certain pages in particular, such as friend search and photo galleries, take up so much memory that the browser becomes slow to the point where it is unusable, and may even freeze for long periods. If I am lucky, I can close the tab and regain control. Other times I have to kill the FireFox process.
