Gecko/200708100202 SeaMonkey/2.0a1pre I have several profiles. When I start SM, I get the Profile Chooser dialog. That dialog contains two checkboxes, the first of which is "work offline". Checking this box has no effect. The browser starts online, and is able to fetch any URL. Reproducible: 100%
Should this have been filed against the "profile manager" component? I don't know if "profile chooser" is part of "profile manager" or not.
So, what happened with the old profile chooser was that when you forced the app offline in the profile manager it disabled the automatic offline management. The toolkit profile manager doesn't do this, so the offlineStartup component thinks that the app is offline due to automatic offline management. It then overrides this as necessary according to your preferences. If this is correct then the bug is in toolkit, and should affect Thunderbird.
Created attachment 276769 [details] [diff] [review] Proposed patch I don't think this should break Thunderbird; if anything it should fix it!
Comment on attachment 276769 [details] [diff] [review] Proposed patch looks good to me, but you'll also want a review from bsmedberg since it's a toolkit change.
Fix checked in.
