Tab Origin wot pelmers

Have you ever opened a new tab and later wanted to go back to where it came from, only to realize that the parent tab is long gone?
Maybe that's just me.
Anyway, this addon solves that problem by keeping track of the URL that originated each tab, so you can return to it with a configurable shortcut or by right-clicking in the tab bar.
The default shortcut is cmd/ctrl-shift-u

Note: when a window is closed all the tab parent information is lost. :(

-- Tab Origin does not change the back button.
-- Tab Origin can re-open parent URL if it's closed before the child.
