Show visit count, tags, most recent visit, added and last modified

[Sopor]

In Manage bookmarks i have several columns that shows: Visit count, tags, most recent visit, added and last modified.

When scanning for broken bookmarks or duplicates i can't see any of these values.

That would have been very nice if there was options to enable and disable these values.

If i have a newly added bookmark that is broken there is a higher chance that it is not broken if it was added yesterday than it was added for five years ago. If it was added yesterday it is something i want to manually check before i delete the bookmark.

Same thing for duplicates. A bookmark that is recently added is mostly the one i want to keep.

So far I always open the bookmarks in a new tab to double check it's indeed dead cuz there are obviously false positive happening a lot (and it's not the dev's fault but how internet works, sadly).

I suggest you using the addon https://github.com/vaeth/bookmarkdupes that can easily do that.
I would not complain if @cadeyrn add it as well :D

Showing the creation date of the bookmarks is already on the roadmap for Bookmarks Organizer 4.2, see #166. Tags and last modification date are not accessible by WebExtensions. For visit count and last modification date the add-on would need the permission to access the history. That's nothing I would do by default in an add-on for bookmarks management, but this could work with an optional permission that can be requested at runtime.

@Illegal-Services Bookmark Dupes doesn't show any dates as i can see.

@Sopor I mean that it's able to delete older OR newer bookmarks, not that it can display dates.
if you want to see date, you can use bookmarks file exported, in a text editor, and if you wanna parse it, you can use one of my project, called bookmarks parser, that is on my github.
Sadly I didn't include option for keywords or labels or tags i forgot the exact name on FF, but I can easily add that as well if I want to
