Firefox cannot open/reload any websites after resuming from a system standby. I have to close the current window and start a new session, then it works again
I am using Firefox v 13.0.1 (Mozilla Firefox for Ubuntu canonical 1.0) on Ubuntu 12.04 LTS. Whenever my system resumes from standby I am not able to open/load any webpages in the Firefox session that was already running before the standby. I don't get any error message, but the page doesn't load at all. If I close the session and start a new one everything works fine.
