Integrates Firefox even better into the elementary theme (especially the tab button. That green thing from the ff gnoem theme always bugged me).
However some icons (for example the history icon [namely the places/folder-recent icon, which is also the recent files icon]) are not related to what they are and have better equivalents within the elementary icon set.
The panel styles still don't fuly match the panel style from elementary, but it's a lot better than it was earlier when I last used this theme.
As soon as australis reaches the main version I'll probably disable this theme, or fork it on github (if I can find it) and make it a pure icon theme, so I get the australis tabs.

This review is for a previous version of the add-on (2.7). 

Cheers for the review.

The must have theme for all elementary OS users. IT looks just perfect. I am not sure if I like, that it always shows the forward button, but I can live with it.
The sad thing: it breaks the notifications style. Notifications look really ugly and have a random size (based on the content). This happens, since ubuntu doesn't provide a libnotify implementation with feedback. I hope elementary OS will get a new default notification library which will support it, so firefox uses system notifications.

This review is for a previous version of the add-on (2.1). 

The forward button is a part of the elementary UI design for a web browser. I understand that Firefox only shows it when there is a page to go forward to, but I've also been thinking about removing it. About the notifications, this theme doesn't modify the Firefox default notifications (apart from some icons, eventually), so I can't really understand why you say "it breaks the notification style". Maybe I'm missing something.
