I have but seldom use Firefox. Earlier today I installed the current update/version just to see if I could see what you are talking about.

I do not see any difference between the "old" and the "new" - though I don't use many add-ins.

So, what is it about the new version that's so "repugnant" to you?

And what was necessary to return it to a semblance of your old Firefox?
