Asa Dotzler writes “10 months and over 5,000 bugs squashed — Firefox 1.5 Beta 1 is available for download.
You can find out more at the Firefox 1.5 Beta 1 start page and the Firefox 1.5 Beta 1 release notes.
This is a Beta and it does contain bugs. It might even melt your hard drive. If you’re interested in getting a sneak peek at what’s coming up in Firefox 1.5 or if you’re participating in the Firefox quality assurance and testing efforts, you should get this Beta. Otherwise, stick with Firefox 1.0 until we ship our final release of Firefox 1.5.”
