OS is Win 7 Home Premium. Never had a problem with all prior Firefox generation, incl. the last one (3.6.3) from which I upgraded to 4.0.1. Obviously no real connections problems exist since in the same time I can run successfully IE8, my Outlook and other programs that use the internet. What say you? Note: It would be prudent to state WHY EXACTLY could not connect rather than the historically dumb message that programmers put and tells me, the user, nothing. After all, one can see that there was no connection w/o the message

Probably a Firewall problem, details included for each Firewall that may cause a problem.

I have learned in the meanwhile that indeed it is my zoneAlarm's Firewall issue and even discovered that they have a wrong design, not just a "bug" where one can't override their blocking and that they are working on it right now. But on the other hand, and regardless of their problems, it is not so nice that some programmer in Mozilla decided to change Firefox Add-ons interface, in all probability for no good enough reason or, that the design of that interface was conceptually poor in the first place. An interface, especially to an external world should be crafted with particular care. In short, programming is too serious of a business to be left for programmers...
