Rated 4 out of 5 stars
This was a great extension... When I first installed it, it worked like a charm. However, after I cleared my history using firefox (not using the extension), the storage for the extension is now always empty even after a month of use. I use a mac if it makes a difference.This review is for a previous version of the add-on (22.214.171.124.1-signed).
The actual storing is not done by the extension itself, so something else must be at fault. Are you using Private Browsing? In Private Browsing mode nothing will be stored at all. Contact me directly (email@example.com) and we will figure this one out.
