They said on the Firefox blog post that an average user would see 30% less memory usage. Well, I opened all 117 of my bookmarks located in one bookmark folder using the ‘Open All in Tabs’ feature to see what would happen between Firefox 5.0 and Firefox 7.0a2 and the results were amazing.
We saw a reduction of 510,524K, which is 39.7% less system memory usage. By making the move to Firefox 7.0 Aurora we were able to use half a gig less DRAM!!
You guys should try this one out!
