Still Works Rated 4 out of 5 stars
Ver. 1.1.10 works fine on FX 23.0.1.
For example, following Places URI shows all the bookmarklets in your bookmarks.

It'a pity that very few people use this tiny, good addon. You can get your own bookmarks button which is customized with Places Query URIs. See the screenshots above.
