If I run firefox with an active Internet connection, it starts in about 1 second. If I run firefox without an Internet connection, but with an active network connection, it takes 33 seconds to start. The start page is blank and updates are disabled so I would expect no network activity at startup. This also affects Thunderbird. Version info: Arch : x86_64 Version : 12.0 Release : 1.fc16
Yes, I have seen it too, it's not restricted to firefox only. I had the same problems with mc for instance.
Hm, I'm unable to reproduce. Can you please attach output of "ifconfig" a "iwconfig" when firefox fails to start quickly? It looks like a special network state, maybe DNS failure or so.
I can't reproduce this anymore so perhaps other updates have fixed it.
Okay, thanks for the update.
