Review for Save Images by John Corliss
Rated 5 out of 5 stars
Don't know why the page says that this extension isn't commpatible with FF48+. I just installed it and used it with no problems whatsoever. My copy of Firefox is 32 bit, 50.0.2.
This review is for a previous version of the add-on (1.1.0.3).To create your own collections, you must have a Mozilla Add-ons account.
