excellent

Keeps prompting me to download this extension, which I've done multiple times (also, I've reinstalled Firefox). Bookmarks do not sync.

Boa.

Impossivel instalar. Impossible to install.
Instalação interrompida porque a extensão parece estar corrompida.

me duplica y triplica los marcadores, funciona en general bastante mal

Confusing.

No longer works with icloud as every time you install it it is not recognized by icloud and wants to install it again

Me gustaría que se pudiera sincronizar la navegación

This extension is not being recognized by the iCoud App. Keep asking me to install this extension!

Last update July 2018! When I use it with Firefox 77.0.1, it sorts my bookmarks alphabetically. Every time I reorder the bookmarks according to my criteria, the addon sorts again by alphabet. As soon as I have finished sorting.
it is no longer usable.

tres bien
