Ummm....
... Is it just me or is it just 'the beta has bugs'? that this article is telling me?
Its interesting to know the RC is delayed right enough, and that quite a few Add-on's will not be available. However I suspect that many add-on's get abandoned shortly after there made, so I would only expect popular or active add-on makers to have V4 stuff ready for prime time.
That is fine by me, as I don't want to wade though a huge pile of 'left overs'. I mean I use the flags Add-on, noscript, WOT and spell checker... and that funky Lazzerus form recovery. But I would use FF with out them in the knowledge they will come along in due time.
What I do want is graphics acceleration, HTML5 support and any other new toys that make JS faster. I can't remember them all but there was other features that I am looking forward to as well, the nicer way of organising my damm bookmarks is one of them, and makes FF much better for ppl on touch screens. With that said even if its not there on release, at least I can just wait and do a small revision update to get it l8er, and I look forward to a new generation of plug-ins that expand that type of UI.
And no I will not be using FF4 until I am prompted by FF3 to upgrade. I do understand business are different, however I suspect if you have already configured FF3 to the way you like it, FF3 to 4 is gona be easier than it was going to FF in the first place, all-be it with quite a few months of lag.
Just my 20c.
