I love Firefox Multi-Account Containers, but would really like to see one additional feature. Directly below Open in '''New Container Tab''' I would like to have '''MOVE to new Container Tab''' (IE change the container for an existing tab). Currently I need to Open in New Container Tab and then delete the original tab. The existing configuration options are not sufficient, but should not be removed. USE CASE: While surfing I may open a number of tabs related to a product or topic. I may then click on a link for a similar or different item (lets call it subject). At some point I may have a number of tabs open for 2 or more subjects. At this point I decide to move some to a new container to help me group the subjects. Currently this is 2 actions as opposed to 1. Not sure if I am missing something. At this point none of the other add ins appear to, at least from their description, offer this function and I prefer to use as few add-ins as possible. I realize that I may need to relogin to the site to perform a purchase.
