Firefox keyboard shortcuts

Cross-platform set of key commands — I’ve long since done command-1, command-2, etc to go to the first, second tabs (and so on), but didn’t know (or had forgotten) the command for next and previous tab:

Ctrl-tab (next)
ctrl-shift-tab (previous).

On Safari, all you have are these commands (next, previous) — no direct to specific tab commands. The Safari commands are command-} and command-{ –which is the same as command-shift-] and command-shift-[ .
