REMOVED all my pinned tabs! Created a bunch of work for me doing exactly the OPPOSITE of what I needed done. Ugh.

Force the first page to be Pinned, even with history and cookies disabled. Perfect.

Kind of breaks when you try to use multiple windows. https://addons.mozilla.org/en-US/firefox/addon/persistentpin seems to be the better alternative

This extension broke Tree Style Tabs. Removed all trees / sub trees.

Excellent. Thanks Thomas.

This is one of the few addons that just pin all tabs and pin and unpin individually as well. Very straight forward and other pin addons seem to not do this without other complications. The beauty is in the simplicity. Well done Thomas.
