Any way to make this the default behavior? I mean, that the extension recognises the last used container, and open any new tab on that container.

On Mac, Alt+c works but only if focus is not on a text-entry area. Otherwise the normal Alt+c action types the letter 'ç'. Please change the key combination used on a Mac, or let the user alter it.

This add-on looks useful, but the shortcut is not working on mac.
Any idea?
