yabbado, if your thinking is that browser vendors can't innovate, then I'm sorry, but you're probably not going to get much support there. Firefox (or any other browser) is not an operating system; they have never promised nor have they ever designed for a "windows style" track record of backwards compatibility. Personally, I don't like the update scheme that they've decided upon either; they're trying to follow on Chrome's footsteps which also updates something like every 6 weeks.
But maintaining backwards compatibility with everything, yet still continuing to innovate? Sorry, but that's just impractical.
Mozilla can innovate as much as they like, I am only concerned with my browser/Internet compatibility. Jolly jelly beans to Mozilla.
If Mozilla want to update their browser every 5 minutes to outstrip all the other facilities that make Internet life wonderful, then I wish them good luck and a happy death.
When my browser controllers go berserk and embark on some idiotic, brainless dash to becoming a complete mess, then it is time to change browsers. Like I said, IE seems to be mentally stable at present so reluctantly I will go back to Microsoft. IE do not have some brainless fetish to even touch that insult to browsing called Chrome let alone compete with them.
Why Mozilla has embarked on a path to self destruction, my mind cannot comprehend. Any suggestion that this insane activity is some attempt to compete with that utter shambles of a browser called Chrome is too much for an intelligent brain to understand.
It looks like a Lemming syndrome to me.
Chrome is about as useful to Internet browsing as a broken hammer is to banging nails in. So why completely wreck one of the finest browsers that ever existed just to compete with a load of amateur rubbish ?
