ff-jump-to-tab

A Firefox extension that changed the hotkeys for switching between tabs from Alt+# to Ctrl+# to align better with all the other tab-related keyboard shortcuts. Sadly it looks like this will never be fixed upstream; hence this extension! It's based on @zbraniecki's this, but also makes Ctrl+9 jump to the last tab, and Ctrl+8 to the first non-pinned tab.
