The changes are subtle but it’s good to see that memory usage is being optimized and the stability issues fixed with subsequent versions.

My biggest problem with Firefox has been the gradual slowdown and bloat over the years–performance hitting, memory leaking and resource hogging. I’ll give Firefox 9 another shot, hoping that it runs as fast as it once did.

I have already started using it and i guess its new version 9.1 is also available now. Btw i didn’t notice any increase but hope it must be doing so in the background. :D

Firefox 9 is 30% faster then Firefox 8, however it’s still much slower then Chrome. I just did a benchmark and it wasn’t even close.

My biggest problem with Firefox’s new rapid release cycle is add-on upgrading.
