I don't use Ubuntu all that often, but have heard chatter that it's a known issue with the network manager. (New since Firefox 2 didn't rely on it for online/offline status report.) The recommended workaround seems to be to run gksudo gedit /etc/dbus-1/system.d/NetworkManager.conf through the terminal and change <allow send_interface="org.freedesktop.NetworkManager"/> to <deny send_interface="org.freedesktop.NetworkManager"/>
Hope this helps,
I have downloaded Firefox 3 to Linux Ubuntu Gutsy and when I open the browser I am offline
Unchecking the offline box brings it back online until I close and reopen
Checked about:config and found the following
"browser.offline userset boolean false"
Is this the proper configuration or should it be "true"
What do I need to reset so as to stay on line all the time
