Firefox View is great, but there doesn't seem to be a shortcut to quick-switch to its tab, which isn't accessible via Ctrl+1–9.
Thoughts on assigning either Ctrl+` (backtick) or Ctrl+0 for this purpose? I think Ctrl+` is preferable, because View is pinned as the first tab, and it's also less likely to be accidentally pressed. Activating the shortcut would open the View tab if the user's on a non-View tab, or restore the user's previous tab if they are on the View tab.
