Still Works Rated 4 out of 5 stars

Ver. 1.1.10 works fine on FX 23.0.1.

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.

This review is for a previous version of the add-on (1.1.8.1-signed.1-signed).
