I just tried this on dev and got this error from the console: Error: Syntax error, unrecognized expression: [name=Firefox-24.5.0esr-build1-data_version] I'm guessing that there's either some quotes required or that the "." in the name is breaking something.
FWIW, that's a jQuery error rather than backend, probably at https://github.com/mozilla/balrog/blob/master/auslib/admin/static/js/releases.js#L61 so I suspect the . is the issue. Might need to s/./_/ in html entities, yet still talk to the right enpoints. Fun :-S
Not a problem in the new ui.
