bookmarks are not deleted when I turn off the add-on

and this is how you lose your bookmarks, went into another room of my house on another PC, same FireFox account, Private bookmarks were not there, went back to my other PC.. bookmarks gone.. lost them in about an hour

Doesn't work on Firefox Developer 91.0b8. I checked the github page to submit an issue, but it seems like the project is dead and the developer is no longer responding to issues... I don't think this should have the "Recommended" tag as it's no longer being maintained.

changed password without user confirmation, lost data. backup bookmarks or they will be lost. doesnt actually work after a while. 5star reviewers lie or gave 5 stars too early.

turn off the sync to use it

After a Firefox update, my password doesn't work anymore. It seems this happened to other people too. The addon hasn't been updated in two years so I don't recommend using it. If you do use it you should regulary export your private bookmarks as plain text file

this extention won't let me add any bookmarks

RSN

All in all: good idea but problematic expirience.
It deleted my hidden bookmarks - probably in a sync between two machines running at a same time, but there is an option to RESTORE bookmarks so it is not the end of the world. Can't wait to see it fixed.
