Problem With Addon Rated 2 out of 5 stars
I love your extension, but the x is missing from the tab. I have the latest version of FF, and the 1.2 beta of Hide Tab Bar With One Tab.
Can you remedy this ASAP?
It should be fixed in beta2. That should show up automatically in a few hours/days or you can get it by clicking on "Version Information" and the Version 1.2beta link at the bottom of the add-ons page here.
