I was deeply disappointed when I "upgraded" Opera to the latest version, as it has been dumed down and thing I used to like having, such as the ability to turn off GIF animations and generally block content per-site, are gone. Maybe some plug-ins will help, but overall its almost pointless.
Chromium gives me a webkit-based browser without Google's spying, so what is Opera actually offering to justify their existence? OK the "turbo" feature is occasionally useful, but that is about it.
Will Firefox quite copying Chrome's "users are morons" approach and stop dicking around with the GUI? You know, hiding thing and/or removing them because a couple of developers don't use them.
Actually, its an anti-rant as I am pleased MS has finally bitten the bullet and decided to ditch all of the legacy crap in IE. Yes, I know a lot of organisations are IE-bound but for the love of $DIETY just fix those. MS needs to move on and if they stick to open standards, and ideally open their browser (even if under a restrictive license) all will benefit.
