Sorry, I don't accept contributions. You are welcome to report the bugs at the support site though: https://github.com/rharel/webext-private-bookmarks/issues What's missing to make this extension five-stars?

Thanks. Just one comment about security: it is NOT guaranteed. I can only do what Firefox allows me to, but ultimately if Firefox decides that when an extension tells it to delete bookmarks that it should keep a bit of info about them somewhere internally, there is nothing I can do about it. This extension is like a door lock - to a determined burglar it is just an inconvenience, but to the 99% of burglars too lazy to go through the trouble it does the job. Just wanted to emphasize this point. Thanks for your review.

Thanks for the feedback. I'll consider your suggestion and it may be included in the next release. Cheers.

You can already have the Private Bookmarks folder appear wherever you like, see the add-on description for details. A context menu to move a bookmark to the private bookmarks folder is a good idea, I'll consider it. Thanks for your feedback!
