Useragent AX attribute on Netscape? (And now on Firefox?)

[JAB Creations]

What is this AX attribute I'm seeing?

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3 (ax)

ActiveX plugin?

Yes, the (ax) relates to ActiveX, but not the whole MS ActiveX, just support for the ActiveX control for the Windows Media Player (for the embedded player). You will only see the (ax) on Windows builds of Mozilla/Firefox.

See the reference documentation for more info on Gecko user agent strings:

[developer.mozilla.org...]

Careful how you parse the bracketed part of the string - see my user agent string, for example:

Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.10) Gecko/20050725 Firefox/1.0.6 (Ubuntu package 1.0.6)

At the end you can get a lot of information about the type of vendor build (ie. a version of Firefox or Mozilla not built by the Mozilla Corp.)
