Hi! Yesterday, I experienced strange behaviour with Firefox. I was sending two files via Gajim to a friend, for which Gajim was listening on port 3000. After that, I surfed on YouTube. After a short while, I wanted to send a third file, but this time, Gajim told me that port 3000 is already in use. I was confused and thought that maybe Gajim didn't close it correctly. Therefore I did a netstat -an which showed that the port was really in use (but no connection to it IIRC). Then I did lsof and saw that the port was used by Firefox. So Firefox opened the port just in the 5 minutes where I wasn't sending a file. And the strange thing is that it listened port 3000, one of the few ports routed to the outside world, which was in use 5 minutes before by Gajim. Stupid as I was, I instantly closed Firefox instead of taking the network cable out and connecting to port 3000 via telnet. After I closed Firefox, the port was closed again. I closed it the normal way, which means I just closed the two tabs. Now I'm wondering: Is there anything that could cause this behaviour? Or is my system definitely compromised and I should reinstall it?
The versions I use are: Firefox: 2.0.0.4 libjpeg: 6b-1 zlib: 1.2.3 expat: 2.0.1 libtiff: 3.8.2 libxml2: 2.6.29 libpng: 1.2.18 libxslt: 1.120 Flash: Don't know how to look it up. It's either 9 Beta or 9 Final. Anyway, the MD5 hash of the plugin is 0273c3d183c8665f21175896ae4d1b4e if that helps.
