Please update this and make it compatible with another indispensable extension, Add Bookmark Here 2. That's the only reason I don't use it. Thanks!!This review is for a previous version of the add-on (1.4.1-signed). This user has other reviews of this add-on.
I think what you're asking is not a matter of compatibility but actually a combination of these two add-ons (to add 'Add bookmark here' functionality in 'Bookmarks menu') and that is not something easy if not feasible.
