Hi Bill, sorry about that issue. It has now been fixed! Everything should work correctly when Firefox downloads the patched version.

Edit: Did you update Tabliss? You can do this by going to Addons > Right clicking Tabliss > Clicking "Find Updates"

Edit2: There aren't any external dependencies, but the OS does provide the time through the browser. Have you manually selected a timezone or is it set to automatic? Please email me at [email protected], as this seems to be a new issue I haven't encountered yet.
