Well. Is there an API to update the default bookmark location?As is usually done by clicking on the collection star.

Perhaps a policy would do what you want. There is a list of policies on github and searchfox.

There is also autoconfig.js which enables you to preset preferences. (Remove the blank space in the second link.)

I'm using a third-party bookmark add-on “Bookmark Tab Here”, but Firefox's bookmark button doesn't remember the add-on's most recent bookmark location.
