I haven't used containers much, but I would like to, and FF Quantum as-is just doesn't suffice. As a web designer, Reddit moderator, and as a serious power user, sometimes I need to access pages without being logged into my main accounts, or preview CSS/layout changes, and even work on multiple accounts at a time. This plugin makes it far easier to utilize Containers as they should be.

EDIT: It now works perfectly after installing Deja Vu's FOSS fonts!

I don't know how this isn't part of the default container add-on. It's absolutely necessary so you can assign sites to the proper containers as you encounter them.

https://www.youtube.com/watch?v=LrxubHeiIfw features use of Switch Container to send a page to a container, then de-contain the page.

Also in the screen recording: experimental Conex 0.0.66 with a preference to disallow movement.

The disallowance in Conex does not disallow use of Switch Container. The two extensions complement each other very nicely …

Excellent

This is just fantastic! Containers are a game-changer for me, but I was frustrated because I always forget to open new tabs in their right containers. Thank you for fixing that!

This is perfect except that I can't switch from a container to not a container, which would be nice.

Edit: updated to five-star review now that decontain is here!

So often a link will open in the generic container, when I want it in a specific one. I had been doing the "copy url; close tab; open new container tab; paster url" dance, but NO MORE!
