The first thing you'll notice when using Australis is its curved tabs and the clear distinction between foreground and background tabs.
However, since it landed in the latest Firefox Nightly, it will most probably be available with Firefox 28 which will launch March 4, 2014.
Did you ever try Opera v12.16 Portable?With somewhere over 40 tabs open I only use about 620-680mb with the portable version (which is the only v12,0 I have on this machine).
What's different about the "portable" version?
Does it include Flash?
Funny thing, the tabs still down work at all for me in Australis, at least in Linux. I click the tab and nothing happens
