Cannot save settings for multiple container of a same site. And when I reload, the duplicates will gone or will only use one container.
Which is not what I expected. Well it does what it does but the way it does it makes me think the title is a bit misleading.
Multi-Account container? NO just call it Firefox Web Container please. Or Firefox Multi-Web Container.

why did you remove this functionality in the newest update to Firefox? why are you making the program worse rather than improving it?

Extremely helpful for web development. Makes it trivial to access the same application with different credentials at the same time.

Amazing. Missing feature to set a start page for Container type

Easy to use - works every time

This add-on alone is a reason to use Firefox
