Oh thank God someone made this add-on!

I've been wanting this for ages... So the add-on, as you might guess, adds a context menu to right-clicking a bookmark, allowing you to open it in a container.

As a web developer, Redditor with subreddit and bots to test, as well as a other administrative work I need to do which requires multiple accounts, this add-on makes things so much easier. Now I can just right-click a bookmark, open in container, and get to work, rather open the bookmark, let the page load, switch to a container, and then let it reload the page to then use it.
