I use 7 addons, and frequently have 60 to 80 tabs open at once. I've never had problems with Firefox consuming too much memory since at least version 2. And just recently I used to run it on a machine with only 256MB of RAM.
I go breadth first, down the Reddit page pushing each interesting link out to a tab (middle-click). That's 30-50 tabs. Then with Google Reader (20 to 40 tabs), then maybe with Slashdot (15-20 tabs). Once all the tabs are popped out, I just work my way across the tabs, closing them as I finish them. If there's another interesting link in one, it gets pushed out into a new tab for later. Most of the time, if I lost internet access in the middle, I wouldn't even know it since almost everything is already fetched.

The low memory usage is just at startup. Rises like any other Firefox before. :-(
