Echofon Problem

I'm having a problem with my echofon at my desktop. I doesn't receive any updates at all even though it supposed to get them. I can post new tweets from my Echofon, though. This happened on my Firefox and probably on my Linux desktop only, since i have no problem with Echofon on my iPad.

I have removed the .mozilla and start a fresh Firefox configuration and reinstall Echofon, but i still have no solution for this. I even asked Echofon's Twitter account but no help has been given up to now.

Any ideas on how to solve this problem? It's annoying to open up Twitter when i can do it via the Echofon's panel
