2. Restart Firefox
Actual Results:  
My history is wiped out, any open tabs from the previous session are not re-opened

I should have been able to see my previously opened tabs return, and continue from my previous session

What errors are listed in the error console when this happens?

Can you tell me where the log is located on OS X? I forgot to check the console when I reported the bug (the first time it occurred I wasn't sure what caused it, and so didn't report it), but I'll check my log if I can find it.

Ian: From the menu bar, check Tools -> Error Console when this happens to see if there are Errors in the Errors tab.

On the Mac you can also run the Console app which you can find by typing the app name in spotlight. Console can often give helpful errors that can be copied and pasted into the bug.

This prompt isn't from Firefox but from an extension.
