[Bug 236306] [NEW] firefox 3.0rc1 hangs

[daemacles]

Public bug reported:

Binary package hint: firefox-3.0

Using Ubuntu 8.04

An upgrade through the update manager of Firefox 3.0b5 to 3.0rc1 on 30
May 2008 causes Firefox to hang while initially loading and also
frequently while browsing for minutes at a time.

Removing all plugins, ~/.mozilla had no effect, nor did removing and
reinstalling firefox.  Firefox 2 works fine.

Attached is output from 'strace firefox-3.0', highlight below which
seems to be a stall when trying to contact localhost??  After strace
prints the last line, Firefox hangs for a while then continues, strace
spewing out more output.  The same line dealing with sin_addr etc is
always what gets displayed when firefox hangs.
