Is it possible to open a new tab in a specific container when using Firefox Containers?

Question

I'm using multi-account containers in Firefox to keep my tabs separate from each other. I'm looking for a way to open new tabs in specific containers.

Using Cmd+T opens a new tab in a default container. A long click on the new tab button shows a dropdown menu of available containers and I can choose one from that list. I'd quite like to be able to do it from the keyboard though.

I've set up some domains to open in specific tabs but it's things like Gmail that doesn't work for. I have separate containers for personal and work Google accounts and want to be able to go directly to either of them.

Is there a command-line option to do this? If that was the case I could set up a third party app (such as alfred) to call Firefox with such an option to set the container.

Answer 1

Ctrl + . is the default shortcut to open the containers panel.

I found this by doing the following:

1. navigate to the Add-ons dashboard (Tools --> Add-ons or Super + Shift + A on mac)
2. click the gear at the top of the list
3. click "Manage Extension Shortcuts" (this lists all shortcuts for all extensions)
