It would be useful to be able to configure some extensions to be "global". I use multiple profiles so I can be signed in to some websites with different account levels, but I need to use 1Password with all of the profiles. Currently I need to configure the 1Password extension multiple times, once per profile, even though it's the same account, so it could be useful to have an option where I could configure this extension once, and have that available to all profiles.
Not sure if this would be possible really, but I thought I would share the idea nontheless.
