I absolutely love the containers feature in general, and the Facebook one in particular.
One severe use case limitation (for me) involves using containers to separate work/home accounts. I am a developer, so I do a lot of screen sharing / presenting.
Theoretically, I could use Firefox containers to separate things into "work" and "personal."
However, all containers have a shared autocomplete history for the URL bar.
1. Suppose I visit "GirlsXXX.com" in my "Personal" container
2. The next day at work, I am screen-sharing and using my "Work" container
3. I type in "github.com" so that I can visit Github.com
4. As I type "g-i-t-h-u-b", "GirlsXXX.com" will be one of the autocomplete suggestions after I've types "g" and "gi"
To be fair, both Girls and Git have the concept of commitment. And I've got an extensive .girlsignore file. But under no circumstances should a push be tried on the former, especially if a gentle pull does not succeed.
I keep all job related stuff in separate desktop VM and only ever share that window over Zoom/MSTeams/Slack on the host system (better native pref). No surprises in years.
