perfect!

我终于可以在Linux的Firefox和Windows的chrome之间方便的同步收藏夹了！这太神奇了！
配合坚果云或者nextcloud使用起来简直太有效率了，非常感谢开发者！爱你！
I can finally easily sync favorites between Firefox for Linux and Chrome for Windows! This is amazing!
It's so efficient with jianguoyun or nextcloud, thanks to the developers! Love you!

Hands-Down best bookmark cross-browser sync.
The ability to change sync frequency/authentication/locations is perfect!
If you use Nextcloud, it gets even better!

Great Add-on. Connected it to my Nextcloud and had an instant backup of my bookmarks/Sync to other devices. Gives you great options in terms of how/where to save the bookmarks, sync by merging Server and Client or make one override the other. Has all the options you need to make a a customized setup. Thanks!

Install was super simple. Add to Browser, Fill in Server and Login, Create a Sync task and you are set.

Had no issuses, works as intended from the first second.

完美契合我的需求，作者太棒了

Love It - works like a charm.

It worked very well and the feature that you can sync Bookmark folders is pretty nice. However, since the upgrade to the newest Nextcloud/Bookmark version it has an error:
Nextcloud log: Call to undefined function gmp_init()
Edit: Now it works again, thanks for the help :)

Probably the only addon that supports sync on selected folders (not all bookmarks).
One feature i miss is support to force pull/push sync, sometimes i don't want to merge.

Nginx + webdav module + floccus = ❤

First: works as it should without any restriction, very very good extension both for Firefox and my Nextcloud. Fifth star not assigned in fact that there's no Firefox add-on for Android version and so it is not usable for me for I don't have other devices to sync than my Android ones.
A minor proposal: A list view of the bookmarks like in Firefox itself would increase usability. The graphics for each bookmark are a bit large and if you have hundreds like me or maybe a thousand of them you're forced to scroll a lot or to use the search bar extensively.

Appendix: The list view is a comfortable advantage, thanks a lot.

Works as advertised, great dev support.
