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.
- Firefox 5.0 used 1,286,916K of memory
- Firefox 7.0 used 776,392K of memory
Optimized Memory Use:
- Improved memory management: For many users, memory use is reduced by 30 percent or more, responsiveness is enhanced
