I use this for bookmark management and I find it useful. I have not used other features. However, the latest version wants access to my data for mozillazine.org. I can't imagine under what circumstances that would be legit and am not approving it. I see no explanation. So I guess I'll be stuck at this version till I find something else.

Very nice. I use to move bookmarks between folders.

Rather useless, it only loads the tabs for the one window that is open, not all tabs in all windows. I expected given the super complex and confusing interface would be worthwhile to work across all windows at once, but this is not the case. Ultimately this clunky interface is not worth the time, as there are plenty of other add-ons which do these simple tasks much more coherently.

After first use this addon looks as a most advanced I've ever seen. The only feature I'll request for is duplicate finder. I want to find duplicate in single column or set of columns , mark it and delete them.

It has been true love 😍 as soon as I found it 👍

powerful functions.
It would be better if there was a modern looks, as well as an open source repository.
