Firefox 3 beta 4 was just released. I have been upgrading without waits and have been running the greatest firefox all the time. When I advised a friend, he said he does not upgrade since his extensions doesn’t work. I was like come on!! You don’t know, Extensions.checkCompatibility ?
So friends, don’t stop yourself any further, Install the latest wonderful thing here. Again, here’s are the release notes to find how much greater it became. And here’s the detailed performance review.
Firefox 3 Beta 4 includes more than 900 enhancements from the previous beta, including drastic improvements to performance and memory usage, as well as fixes for stability, platform enhancements and user interface improvements. Many of these improvements were based on community feedback from the previous beta.
And for those who had been laying back for extensions that doesn’t work, quickly browse to about:config and create a new boolean value -> extensions.checkCompatibility and set it to false.
Most of my extensions work without breaking anything.

First of all why are you still on Beta 5. Firefox 3 is easily available. This was useful when the extensions were not available for firefox 3 betas. These days most of useful extensions have been already upgraded to new versions compatible to firefox 3.
