Thanks so much for the reply, deanishe. What about using the Firefox Multi-Account Container keyboard shortcuts in a workflow? Could that work? I'm very new to Alfred having just switched from LaunchBar, so please excuse my (hopefully) temporary ignorance.
Has anyone figured out a way to use Alfred with Multi-Account Containers in Firefox? One use I would love to figure out would be to launch and open a bookmark in certain Firefox Multi-Account Container. Does anyone have any ideas?
