Container Hotkeys от Noitidart

This uses the experimental show/hide tab feature. You must enable set `extensions.webextensions.tabhide.enabled` to `true` in about:config to use this.

Default target container name is "Personal". You can change this in the extension preferences.

Hotkeys:

Windows/Linux:
Open New Tab in Container - Ctrl + Alt + T
Toggle Visibility of All Tabs in Container - Ctrl + Alt + B

Mac:
Open New Tab in Container - Cmd + Option + T
Toggle Visibility of All Tabs in Container - Cmd + Option + B

The "Hide this container" feature of "Firefox Multi-Account Containers" discards all tabs, as you see the tabs re-load when un-hiding. This hides them only, and enables hotkey support.
