If you have one problem you can't say it's not a good firewall. That's what many keeps saying for avast! when they try it for the first time and experience so many problems... we are here to help them. Sure there is a free forum support, but that doesn't necesarily comes from avast! itsels, but from us Tech. We are the ones that spends so much time in here trying to unselfishly help everybody (I hope we are succeeding in that)... that's up to us.
Comodo doesn't have forum but that's just because they just started to deal with that product. If it has problems and issues (although I haven't noticed those you mentioned, oh yes... btw, I just tried new version on my laptop and it works like a charm...), so we need to work on those problems and inform those developers. That's the best way to deal with those things. As I said, there is just few people (tech support) at Comodo, and I am sure many people already send hundreds of requests. We have to understand them a bit. They are dealing with unbelievable amount of information right now...
