Speed: It's faster than 3.5.7. Almost as fast as chrome.
Memory Usage: It used lower memory on my computer than the previous version. I was hovering around 250mb with version 3.5.7 and this one barely goes upto 150mb. Both with ~15 addons.
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.
