doesn't work.

There's a problem with either this extension or iCloud.
In the settings panel for iCloud for Windows there is a section called Bookmarks.
It defaults to Internet Explorer!
There is an option to select Firefox instead but when I do (& click 'Apply') it tells me that the iCloud Bookmarks extension for Firefox is required.
I am already aware of this & have installed this Firefox iCloud Bookmarks extension previously.
Unfortunately, iCloud for Windows fails to recognise this & therefor It's not possible to set it up.

this stopped working ages ago and now i can't sync anything because the addons for pc don't work.. 100% useless

同步的数据乱七八糟，重复太多了，删除了重复的后面又出现了很多重复的书签！

If I could give this extension a Zero, I would. I'm using iCloud for Windows on Windows 10 Pro. iCloud goes in a never ending loop, demanding that the extension be downloaded and installed and then not working -- so it demands the install be downloaded.

What a colossal waste of time!

I refuse to use Google Chrome (or Microsoft Edge/Chredge), but I cannot find a browser for a Windows machine that will let me Sync the bookmarks between Safari and the browser.

Any suggestions?

I noticed that the last update for this extension is supposedly 3 years ago.

Why is it still listed by Firefox???

iCloud for Windows bookmark, although added; the iCloud program continues to tell me to download it so bookmarks will sync...

*** BACK UP BOOKMARKS BEFORE INSTALLING ***

Seemed to presume a few things. First, it alphabetized my bookmarks (the ones carefully arranged in a specific order in my toolbar). Then, as I was fixing that, it just started rearranging them and creating duplicates.

I deleted all the changes and restored my backup. Might have been a conflict with Firefox Sync. Alas, we'll never know since Firefox is my primary browser and I trust open source over closed overall. In the end, I disabled iCloud sync in the Windows app and uninstalled the plug-in.

unable to add due to file being corupt

iCloud from Microsoft Store gives an Error 101 when trying to enable Bookmarks for Firefox and using this Firefox extension

Ist Leider nicht mehr Kompatibel beim Sync über Mehrere Firefox und iCloud kommt es bei der Lesezeichensymbolleiste zu Mehrfacheinträgen

Apple様お願いですので、無限増殖バグを早く治してください。最終更新から2年以上たってしまっています。

Broken 09/JAN/2021 - Not recognized by iCloud being installed. iCloud always asks for Addon to install, but does not work. Uninstall, reinstall, tested all, not working anymore (Windows 10 x64, 19042.685)

iCloud for windows doesnt recognize this is installed and keeps going in a circle - install, apply updates, not installed...and around and around

Obwohl iCloud-Lesezeichen Addon und die passende Version von iCloud für Windows (8) installiert, erhalte ich immer die Meldung "iCloud-Lesezeichenerweiterung für Firefox erforderlich". Ich habe das doch installiert. Verstehe ich nicht. Unter Chrome und Internet Explorer tut sich auch nichts.
Ich brauche das Programm dringend, um Lesezeichen zu synchronisieren. Wieso funktioniert das unter Windows 8.1 nicht?

it consumes so much memory
