With a name like "Tabloc" and a the description "Adds Lock Tab button", I am disappointed to find that this extension doesn't actually LOCK tabs so that that cannot be closed.

This extension only prevents the tab from being overwritten when you click a link inside the tab - it causes a new tab to be opened for that tab. That's great, but that's not what I was hoping for an extension with a name like "Tabloc".

"Pin Tab" doesn't work, either, because you can still close pinned tabs.
