I really like what they are doing with Firefox 3 UI wise. Places is simply one of the best treatments of the horrible legacy UI mess of bookmarks/history of any browser period. This is exactly where I think the browser UI should be heading! I would be very happy for Opera to "borrow" as much of this as possible.

Indeed. Oslo, start your photocopiers!

Precisely, yesterday I finally decided to organize my bookmarks, and after only 20, I realized that organizing them in folders is pretty much impossible, so I started to dream of a new system in a future 9.6 version (after all, the framework is already present in M2), while I wondered how could we keep the same old system during 10 years, when it was clearly out of fashion the same moment it was introduced. Ah, considering how breezy is to organize music files with the right tools, one can only thank the Mozilla team for using similar ideas, and maintaining the old and new systems together.
Well, at least it's still much easier to organize bookmarks in Opera or Firefox than in IE >_<
Lashiec: what performance benchmarks? I've tested the most recent nightly and it is still significantly behind Webkit and Kestrel on most benchmarks. The latest Webkit, at least on some benchmarks is shockingly fast. Its inclusion of the W3C Selectors API makes it 24X faster than Kestrels fastest library performance and 35X faster than Firefox 3's on the Slickspeed benchmark!!!
I don't really know, that's what Chris Blizzard
commented to Ars Technica. I guess he was saying that they focused the development into improving performance within certain AJAX sites (*cough*Yahoo! Mail*cough*) instead of having the fastest engine overall.
