Opera Web Browser 12.15 Build 1748

A full-featured Internet browser, Opera includes pop-up blocking, tabbed browsing, integrated searches, and advanced functions like Opera's groundbreaking E-mail program, RSS Newsfeeds and IRC chat.

Same here! Ever since version 5.04!! Didn't really care for most of the 9 versions, but usually rocks just great. My choice over all other browsers, if I had to choose a default!

Had this update before the notifier was even notied!!

Yes and no.

I miss it because Opera Dragonfly Developer tools will no longer be developed. One of the best.

I will not miss its quirks and buginess.

If Opera just could improve stability for the 12.x release and continue remove all crap they filed up Opera with the past few years.
