only Firefox fails to connect in some networks using Fedora 14
In all but one place my HP Pavilion laptop running Fedora 14 will work flawlessly to use the Internet for e-mail, ftp, http, etc. In one network there is a wireless router - Cisco/Linksys E3000 - that allows every computer to use the Internet normally for wireless or for wired connections, every computer but mine. If I use Google's Chrome I can access the Internet. I can ping any web site too, but the moment I try to access anything with Firefox 3.6.17 there is a long delay and the standard error page appears. Weather or not I use a wired connection is apparently irrelevant. The Windows 7 computers in the same network are free of this curious problem. Strangely I have noted a problem like this, possibly the same problem, with another network at a coffee shop and they both share the misfortune of using AT&T, which is proud to not support Linux ... for customers of course (it's good enough for themselves I'm sure). What sort of additional information do we need to diagnose and fix this technical problem?
