Mozilla's Firefox 1.5.0.4 is available for download even though there is no official announcement from Mozilla yet. Check out their releases section in the FTP folder and download the version of your choice. A worldwide release is most likely to be implemented today at best or over the weekend at the very worst. It is interesting to note that the Thunderbird 1.5.0.4 release notes are already up, even though the Firefox one is still languishing on a hard drive somewhere. Portable Firefox is available for download as well - remember to save a copy of the zip file on your thumbdrive so that you can carry it with you wherever you go. Going portable is a good option if you don't want to leave tracks when you surf on your Office's PC.
