We've had a LOT of feedback on the progress of Firefox 3.0 Beta 5, or as Mozilla calls it, 'Minefield'.
While Mozilla is already promoting Firefox 3.0 Beta 4 as 'ready for prime time' (according to some websites), we can tell you, Firefox is getting even better.
Nightly builds are for testing only and some 'builds' can be buggy.
We've been downloading the nightly builds of Minefield and using it regularly.
Currently, the stable version of Firefox (184.108.40.206) is still gaining ground with 15-17% of the enterprise market (significantly higher among bloggers and 'techies').
Mozilla will make big news when Firefox 3.0 is released and the extensions catch up.
Stay tuned :)
Update: Shortly after our post yesterday, Mozilla posted this page on Firefox 3 Beta 5 (IE: The facts).
