Firefox 1.5 with Qt toolkit?

[MaxAuthority]

http://developer.mozilla.org/en/docs/Configuring_Build_Options says, you can build firefox with the Qt toolkit instead of the gtk one, although it is experimental.

Does anybody know, if it still works with 1.5 and if it's ready for daily use?

If yes, a 'qt' useflag for the firefox build would be fine, but I could also compile it myself, just want to know, how/if if still works?
