[LUG] Firefox blocking

 

On 64-bit debian testing.

Firefox has been running fine on this host forever, but in the last
couple of days it now runs as expected immediately after launch and
for a short while thereafter, then effectively stops fetching.
Comet/Ajax/auto-refresh pages don't refresh, manual reloads and new
pages don't load, but, and this is the real problem, nor do they
timeout, meaning you have no idea that there is a problem until other
symptoms present themselves. Maddening.

Something on the order of 20 tabs spread across 4 windows. htop shows
plenty of RAM and CPU available.

After quitting, which seems visually to complete correctly, a process
called 'firefox.real' is left running.

I haven't checked rigorously, but a first pass seems to show no such
problems visible with character-mode browsers on the same host nor
with Safari on a Mac on the same subnet with the same proxy and DNS
settings. (Subject to revision).

I'm hoping somebody recognizes these symptoms before I go down all the
different possible routes there are for resolving this.
