Hi guys,

I was using FF25 and FF25.0.1 when i observed that the navigator.appName property defaults to "Netscape" when the user-agent switcher had changed it to "Microsoft Internet Explorer".

FF24 allows the navigator.appName property to be switched to "Microsoft Internet Explorer" when using user-agent switcher.

This is scheduled to be fixed in Firefox 28, per Bug #939445 – "general.appname.override" pref is ignored (Firefox 25 regression). It's not yet clear whether the change will be escalated into Firefox 26, but you can vote for the bug to try to increase the urgency.

About the bug tracking system: it's generally not helpful to add comments to bugs unless the information helps the technical solution, but you can register on the Bugzilla site and "vote" for them to be fixed. See:
