Thanks marcobra but it doesnt work

Usually it solve, but there is also this bug https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/191889 added to the faq.

Hope this helps

open /etc/network/interfaces and make lo like this:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

save and close networkmanager. it should now work (you might have to update the routing table or just restart)

Dear Hannes Coetze, that did not help (Unfortunately, my Firefox starts offline, too). Wkr, Michael

I could sucessfully solve this problem, though through a radical method:

Using Synaptic package manager I uninstalled "firefox" and "firefox-gnome-support" completely and re-installed it. Since that Firefox always starts in online mode.

Don't forget to back up your bookmarks and passwords ;-) !! Regards, Michael

Disable and stop Network Manager from services(System->Administration->Services, in Services configuration page stop and disable Network Manager).

for me it worked by changing
toolkit.networkmanager.disable
to true in about:config

thanks mziegler this did solve my problem but i had to make that value false and then again true to make this work.

Thank you again !!!

Thanks - toolkit.networkmanager.disable works for me too. Springnuts.

Thanks! "toolkit.networkmanager.disable" worked for me too... Could somebody add it to the FAQ?

Me also ;)

Thanks mziegler :)

I'm using Ubuntu 8.10 (Intrepid Ibex) and Firefox 3.0.6, and "toolkit.networkmanager.disable=true" solved the problem.

@mziegler

thanks you

Bug still here on Jaunty with 3.0.11. I had network manager uninstalled to fix this (!) but reinstalled to check if things had been sorted.

toolkit.networkmanager.disable works for me too, thanks.

Thanks mziegler
I am using netbook remix 10.10 with FF 3.6.13

I solved the the problem for my own system.
Ubuntu 10.4 had not had this problem with Firefox until recently. With all the talk about Network Manager, I realised I had changed my network manager recently in testing a wireless router that was suffering it's own problems. Forum suggestions directed people to ditch the default Network Manager and install the Wicd Network Manager.
I uninstalled the Wicd Network Manager and reinstalled the Network Manager (original), rebooted the system, and the problem with the Offline Mode was overcome. NOTE: I went through the process again of Swapping the Network Managers and the problem was obviously occurring with the Wicd manager :(
