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

Useless add-on as of late.. Consistently forgets my password and makes me delete and reinstall.. Just look for something better..

Was working good, until recently it doesn't save bookmarks anymore. I added more than 10 links last night and this morninig they are gone. Will be finding another add on like Hush maybe.

I have tried this add on/extension and starts out fine but then it will not work and you will loose your bookmarks that you save.
I even have backed up but it will not load them back up all I get is .... " Sorry the add on is not working and then you have to delete it and reinstall but why go through all of the hassle in the first place?
I tried it 2 times and after a couple of times it will still do the same thing .... Not going to install anymore....
