2024-12-09 Firefox user 14405590 No user interface, no instructions, absolutely nothing to guide use of this extension, rendering it useless. I'd like to know how those users who are giving high ratings managed to use this.

2023-11-06 Avalon27703 This extension has no instructions and no intuitive interface; in fact it has no interface or way to execute it at all.
2023-10-17 Firefox user 13156335 No controls: no menu add-ons, no rh-click context sensitive button, nothing. It might work well if only I could figure out how to run it...

2023-09-08 Franceska Meilleur que l'autre avec plus d'abonné(e)s; l'autre me donne pleins de liens qui sont encore bons comme étant des erreurs.
2023-08-17 firedoge This Addon is awesome! Does exactly what is needed and possible, I was looking for something like this and its actually there! I am quite shocked how many of my bookmarks are offline... like the web was dying. Also very useful on TorBrowser to see if onion sites are down.
