Hello,
My addon is not blocking any native browser features (or other addon features), that would be insane. At least I can honestly say I'm not aware of any such thing.
The dials in my addon are simple links (anchor elements), if the target page is assigned to a container (using the Firefox Containers addon), it will be opened in a container.
The PRO version in my addon only allows assigning specific dials to specific container.
I'm really sorry for the issues, feel free to contact me with more details and we can try to investigate it further.
Best Regards,
Juraj Mäsiar
