Firefox 1.5 user agent

What is it?

[GaryK]

I've seen two new Firefox user agents lately.

1) Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

2) Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9a1) Gecko/20050821 Firefox/1.6a1

Oddly enough I haven't seen any 1.5 user agents. Any thoughts on what's going on here? Are these legitimate releases or rather someone playing with the User Agent Switcher extension?

Firefox/1.4 is the beta 1 release of Firefox 1.5.
1.6a1 may be the alpha release of 2.0 -- Not sure about that one.

Firefox/1.5 final is due out in about a week.

The best source for info on this is the mozilla.org site.

1.6 = current trunk nightlies. The 1.5 code was branched from the trunk to get refined for release, while the more interesting work gets dumped onto the seperate trunk.

Thank you everyone. :)
