Maddeningly bad, constantly stops working. In fact, I've never gotten it to work for more than a month without it losing connection. Then I'll have to spend an hour trying to reconnect over and over, pulling out my hair while all of the Apple instructions don't work at all. Then, randomly, it will reconnect and I will get it to sync for a few days.
Lame.

Used to work, after a fashion. Now, under Windows 11, it doesn't do anything at all.

Não funciona, mesmo com o add-on já instalado, sempre pede para instalar a extensão favoritos para o Firefox e nunca conclui.

Simply does't work. I get a notification I should install this every time icloud starts, but it is already installed. Uninstalled and installed again, still nothing. Thanks Apple!

Non funziona. Doesn't works. Works only with Chrome (tiè!)

The addon should be named "iCloud Bookmarks for Windows" because it only works on Windows. Firefox for Mac will let you install this, don't be fooled.

Não funciona com windows 10...
Não sincroniza...
Devia existir uma opção para forçar sincronização.

Useless...doesn't work properly. Going round and round with installing, applying, installing, applying etc...does not work at all, what a disgrace for a company...

Only for Windows?!?!, I suppose It's a joke

WHAT does this do? It is not explained so I blew it away

FirefoxとSafariのブックマークが同期でき便利ですが致命的なバグがいつまでたっても直らないので使用をやめました。
ブックマークが増殖します。icloudの機能としてあるものなのにアプリの更新もなく放置されています。さすがアップルです。

此軟體在W10根本無法使用 請盡可能更新

Simply doesn't work. When I try to select bookmarks in iCloud configuration, app ask me to install Firefox extension, which of course is installed. Useless.

doesn't work.
