PS. Nightly has been incredibly stable on my Mac. I actually use it in production, for no other reason than I was testing it and have no reason to get an old release since it's never crashed and is incredibly fast.
As stable as Chrome dev channel? I use Chrome dev channel (on Linux), but I'm still a bit hesitant about using the Firefox nightlies.

Sometimes some websites are not shown properly in one of those but all it takes is to switch to another browser.
6 and 7 will include other improvements and features which can be discussed elsewhere. Mozilla will release a new major version every 6 weeks.
I found it very jarring to read that Firefox 6 isn't out yet, but the thread talks as if Firefox 8 is actually out, or very close to being released. In my mind I'm envisioning a weird, staggered, neither increasing nor decreasing of version number release cycle.
I think you're coming from a different angle where all of this is very familiar for you, so you can't relate to the confusion some of us other readers have had to deal with.
I guess FF8 (which just arrived on the nightly channel) will be up for release in late 2011-early 2012.
* August 16 - Firefox 6 * September 27 - Firefox 7 * November 8 - Firefox 8
(This should be very familiar to anyone who has seen Chrome's update schedule, which has three versions in flight at once, staggered by the same six-week intervals.)
