Its really great and has the potential to solve my problem, however is is quite difficult to use when you have a massive amount of bookmarks (1000+). For example, when looking at all the broken bookmarks i wish there was a way to collapse folders or only scan specific folders for errors. The biggest thing is that I wash there was a select all box, or boxes next to all the bookmarks so you could select multiple bookmarks so you can fix a bunch all at once instead of selecting to fix the url of each bookmark 1 at a time. (for whatever reason a bunch of the bookmarks have changed from http to https so firefox doesn't recognize them any more). Also the developer seems to be telling everyone not to leave reviews for recommendations and instead to just leave those on his website. But I would prefer not to do that because then I would have to make a whole new account for that site. Sorry.
