Emphasis on memory optimization
If you want to take a look at how well the feature works, go ahead and check out Firefox’s Aurora channel to download one of the latest development builds. If you’re already using it, it’s only a matter of updating it. The memory optimization feature has been implemented there. The latest Aurora build isn’t working towards Firefox 6, but Firefox 7. Understand this is a an early build and instability and bugs are going to be present. We’ll have to wait and see if this memory optimizer fix will cure problems brought in by plugins installed on Firefox.
