For Firefox 4, You'll Need To Wait Until 2011
An anonymous reader writes "Mozilla said that it will not be releasing Firefox 4 RC, or the final version, before early 2011. Apparently, the bugfixes in the current beta take up much more time than anticipated. Mozilla is working on the feature freeze release Beta 7, which has 14 bugs left. The beta 7 is about six weeks behind schedule and will be released 'when it is ready,' according to Mozilla. It seems as if the original schedule, which estimated that Firefox 4 RC would be released in the second half of October was a bit too optimistic. Microsoft, by the way, released a new IE9 platform preview (PP6) at PDC 20910 today."
What are you talking about? I've been using 64-bit browsers in Linux for years!
I encourage everyone using beta 6 to use the nightly version (http://nightly.mozilla.org/) as their main FF experience. The JS is 10 times faster on most public benchmarks and the boomarks and profile data are not affected even when switching back and forth between 4.0 and 3.6.
I have both installed: 3.6 that comes with my Linux distro and 4.0 unzipped in my home folder and being updated every morning automatically.
