No dialog after clicking star Rated 3 out of 5 stars

I LOVE ABMH2. Thank you for all the good work that went into making such a cool extension! Lately, using the old and new versions, when I click the star in the address bar, the address is automatically bookmarked to my Unsorted Bookmarks folder rather than presenting a dialog to allow me to choose. I have tried changing the ABMH2 preferences and also tried replacing version 17 with version 23, but the situation is not resolved. As it as only just started happening, I imagine that it was caused by a conflict with either another extension, or when I updated to the latest version of firefox (for Ubuntu. I'm sorry but I don't know which versions it change between).Could anyone suggest any common extensions that could be conflicting, or how to determine whether the problem is with ABMH2, please?Many thanks
