long hang with non-responding UI is caused by stalled server
I see similar behavior on the Mac, FF 1.5B1. It seems to occur after DNS lookup (because long DNS queries don't hang FF). It seems to always happen before any of the page content is displayed (i.e. while the previous page is still visible). The corresponding tab displays "Loading" and the spinning progress indicator doesn't move. I'm on a terrible network and so this happens quite often.
I still find this occurs with current versions of Mozilla-suite, most notably on e-bay (where it happens on almost every page-load - the browser "locks up" completely for 5-10 seconds). However, installing ad-block cures this in most cases. I don't really object to loading web adverts (at least, not while I am on a fast connection), but I really draw the line at adverts served up by an overloaded, and non-responding advert-server which make my browser lock up!
I am using Firefox 1.5 and I got the same problem: When loading a page it randomly happens, that Firefox seems to have crashed. (Same symptoms as already described above) The problem appeared not before version 1.5!

Furthermore: My system has recently be reinstalled, so it is not a problem with windows.
netstat reports that the connection is in the CLOSE_WAIT state. [Aside: if you wait for ages, (a few minutes), mozilla will usually un-hang - I can't tell whether this is because mozilla does eventually time-out (after far too long), or whether the offending server has eventually responded] Does that help?
people reporting this problem on macosx can use activity monitor, select their gecko and click the sample button when it happens. save that log to a file and attach it here.

My Firefox 3.0.6 occasionally stopped responding a few hours ago with 100% cpu usage and Process Explorer showed about 3 active NSSWF dlls + more active NT getdatetime or such right below the main Firefox thread.
This page, opened in a tab from a Bugzilla search result, in an otherwise tabless window, failed to come in focus for minutes or more as i took this process graphic. No cursor loading indication, but the search page had a full page loading progress bar, as does this only tab in a new window. Firefox 3.0.6 on Windows XP.
