Security of container-bookmarks?

[mikenrafter]

https://gitlab.com/mikenrafter/containMarks <- I used some code from your extension, but see here, that I shorten the URL required, and I use random one-time tokens, for security purposes.

An attacker, with some good off-sec, could break out of a container, or into another one, if they knew: an existing container-name, and that your extension was in use.

My extension fixes this. I believe you could tackle those two issues. Feel free to utilize some of my code. It's fairly straightforward, and uses a decent amount of comments. There's also a debug mode, for if you want to peel back the curtain a bit.

Thanks for the groundwork you did on this extension. It greatly accelerated my development process (3.5 days!)
