After FF has been running for a while (hours/days), I start getting the error "firefox is configured to use a proxy server that can't be found"

I'm using a 'manual' proxy. When this happens, I can still resolve the hostname of the proxy (using nslookup) and can ping it by hostname with a response. Other browsers continue to use the same proxy successfully.

Changing the proxy hostname to another proxy doesn't resolve the problem--I continue to get the same error. Changing to a proxypac file or changing to use system settings (same proxy.pac URL) also don't resolve the issue.

I've not tried putting the proxy's IP instead of hostname in the config dialog.

Hi htroberts,

Try that :-)

proxy's IP instead of hostname in the config dialog.

Ideally though you should have the Proxy set to use the computer's configuration.

Firefox -> Preferences -> Options -> Advanced -> Network -> Connection -> Settings
