I'm not able to reproduce it with FF34 on Win 7, I got the option "2" after refreshing the page. Could you force the update to FF34 in the options and test again. If that fails, could you test with a clean profile (https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles).
Sorry, it is not possible for me right now to update to FF34, as I currently need to write a workaround for these problems, and I need some means of testing those. Same problem occurs on other user's machines, so I doubt that creating a clean profile would solve the issue on FF33.
I see the behavior described (on Linux). But I thought it was generally considered a feature that we preserve form state across reloads. (Though I admit I generally don't want that behavior.)
