Shortly after announcing that they were implementing a feature freeze on Firefox 3.1 for further bug squashing, Mozilla has announced that a beta version of the browser is available. Firefox 3.1 Beta 1 is up for download now, letting people test drive the first major update to Firefox 3 since its milestone release a few months ago.

Though the beta is available, everyone should remember that beta software is just that – and may have unexpected bugs in it. Mozilla is encouraging anyone interested to use it and report any bugs back to Mozilla. The beta is available for all three platforms.
