500369 - Online status detection broken when FF launches without an enabled network device.

Status: UNCONFIRMED

(Core :: Networking, defect, P5)

Description

[A. Glez. B.]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090616 Firefox/3.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090616 Firefox/3.5

When Firefox is launced whitout enabled network devices and then some device (LAN, dial-up, etc.) is enabled, FF automatically switches to Work Offline mode.

Reproducible: Always

Steps to Reproduce:
1. Disable ALL network devices.
2. Launch Firefox.
3. Make sure FF started with "Work Offline" unchecked.
4. Enable ANY network device.
5. Check FF "Work Offline" status.
Actual Results:  
Firefox now has "Work Offile" checked and is effectively in offline mode.

Expected Results:  
Firefox must not switch to offline state or at least keep the last state.

If there is at least one network device enabled, even if disconnected, this doesn't happen. This bug can be reproduced easily with only one LAN connection, just follow steps 1-3 above then enable the LAN connection and see what happens. I never saw this issue with FF 1.5-3.
This bug is related to bug 355739 and bug 367072.

The workaround for this is the same for bug 367072:
set "network.autodial-helper.enabled" to false.

I was wrong. Even after setting "network.autodial-helper.enabled" to false FF switches to offline mode when a new network connection is enabled/connected.

I don't expect this to ve solved any time soon and I'll very much appreciate if someone any advice about how to set FF to be always online and never go offline. I have very intermitent conectivity and it quite anoying to have FF going offline and saying "do that and click here" every time.
