We’ve had a number of emails regarding the Passpack It! button being incompatible with the recent Firefox3 Beta 5 release.
Sorry, but we aren’t going to be able to fix this issue quite yet. In the past we’ve spent a lot of time trying to fix bugs in any given browser’s beta versions, only to find that they tend to fix themselves automatically once the final release is out.
Thanks for the patience, and sorry for any inconvenience in the meantime.
