seperate topic about firefox, but i thought i would just ask it in this thread anyway..
what's the best version of firefox to use right now? the last versions i was using had huge memory leaks that would suck up all my ram if i left it running for a while.
is there any good and/or best build right now? 
The best is really the latest, 2.0.0.6. Firefox continuously makes little minor improvements and updates.
Its first memory issue is really its caching, it determines if you have a large RAM, it'll allocate a lot of space to cache backwards and forwards pages, so it can natrually go up to 300+MBs of RAM without even memory leaking. Whether this is an issue or not is really a debate, but it is a user controllable value if you know where to change it.
Memory leaks were a big issue in version 1.5, not seen it as much of an issue with 2.0, but 3.0 is supposed to be even better when it comes out.
The other major problem is extensions, extensions don't go through nearly the same QA that Firefox does, so there's a lot of badly written extensions out there. Plus weird bugs if you have a certain combination of extensions installed and they conflict with each other. Fortunately if you have popular extensions, given the open nature of Firefox a lot of the major bugs are reported by the community.
