Comment 17 for bug 421864

Thanks for the tag.

This was fixed right after (alas, not for) alpha 3 by replacing the Firefox icon with the Internet category icon.[1] Whether that one is a good idea is still up for debate. For the actual Firefox icon, we're blocking on a different issue, which is that Firefox on Ubuntu ships with a needlessly small icon — that always looked rather ugly here. The unnecessary version number has also been pulled.

Luke, were you installing stock Ubuntu or a particular derivative?

So, marking this as Fix Committed. It should be shiny and happy for Beta 1 and the nearest daily builds. Thank you for the attention to detail! :)
