Like similar extensions it works with the existing bookmark system by saving each bookmark URL with an extension protocol to make Firefox load the container. So if you ever remove the extension or want to take bookmarks out of a container you have to edit them yourself. It doesn't have a function to do that automatically.

that's useful,thanks

Doesn't work on Mac, Firefox 108. There are no menu items to use. Tried sidebar, toolbar and Library, no luck.

Works great. Suggestion: Say I have 30 different containers. Any way to more simply create for a single URL 30 bookmarks corresponding to those 30 containers? (Right now it seems like the only way is to slowly & manually create the 30 bookmarks.)

I am using this now, since the "Multi-Account Containers" from Mozilla themselves does not support setting a container to open my bookmarks with (please fix that Mozilla...).

What I wanted to achieve is, that I have separate bookmarks (and containers) for each of my YouTube Channels to manage, without having to change accounts constantly - thanks to this extension, this is now possible.

I also reviewed the code and found nothing shady - still would like to know why the version on GitHub doesn't match the version installed by Firefox itself (I reviewed the code installed on my system) - maybe Vance Spears can give us an update here ;)

All in all good work and once again thanks for this great extension!

I am still exploring the use of containers, but I love the feature for assigning a custom image to a bookmark. I'd like to see the same image assigning to bookmark folders.

Exactly what I was looking for. Could be integrated directly into FF
