All of this has to be done quickly (this is practically muscle memory for me): 1. Open up laptop such that it will try to connect to a wireless network. 2. Launch Firefox. 3. Home page will show an error re: no network connection. 4. Open a new tab, go to another website. 5. If you get another network connection error in the new tab, wait for a connection and pick it up by hitting the "try again" button in the error page. See page load in new tab successfully. 6. Go back to the first tab and hit reload. Get error about not having a network connection again. Basically you have one tab loading a web page and then another tab claiming you still don't have an internet connection.
I've spent an hour unable to reproduce - on windows or mac. my wifi negotiates pretty quickly, so I've also tried disconnecting from the AP when loading firefox, getting the errors in the original report and then connecting.. but reload works fine when I do that. josh - can you supply an http log? https://developer.mozilla.org/en/HTTP_Logging
Assigning to myself while I work on getting HTTP logs.
I haven't been able to reproduce this when I try to do it on purpose with logging. If I figure it out at some point I'll post logs.
