AO3 Bookmark wordcount autofill
This is a simple little tampermonkey/greasemonkey extension that autofills a wordcount tag whenever you open a bookmark form on ao3. It doesn't work on the dedicated bookmark edit page (eg:
https://archiveofourown.org/bookmarks/<bookmark_id>/edit) since the wordcount cannot be found in the html there.
