Such a pain for nothing and very sad to write a bad review. I'm using Nextcloud 19 and Nextcloud Bookmark 3.4.9 with floccus 4.5.0. The first sync process load very heavy the memory of my firefox 78.8.0 ESR (more than 3Gigabytes with one empty tab open !) and of course Firefox is lagging/unusable during the syncing process. After one hour the sync is done, but not usable to another computer. On the other computer with Firefox, I can see only empty bookmark folders. I tried to read the user guide and FAQ but nothing clear. I start to think this add-on is not made to sync bookmarks accross other Firefox, it loads too much Firefox and sync is too slow (my Nextcloud serveur work flawlessly).

Floccus tried to delete bookmarks now the second time, it stopped because
E029: Failsafe: The current sync run would delete 100% of your bookmarks. Refusing to execute. Disabled this failsafe in the account settings if you want to proceed anyway.

Bookmark app floccus is not fit for production. I deinstalled it again.

Great concept and pretty interface.

Sadly, it deleted bookmarks during sync. Even deleted bookmarks on the SOURCE machine in a 1-way sync. The developer doesn't think that's important. Oh well.

Not working with Nextcloud at all, trying to sync my bookmarks is just a mess and I ended up losing all of my bookmarks... Not good.

Be extremely careful with this add-on. It worked great for about a week. However, when I woke up this morning, ALL of my bookmarks have been permanently deleted (was using this with Nextcloud). Folder structure was preserved but all bookmarks are just gone.

Thankfully, I have backups of all my bookmarks across the machines I was using this on. Will only have permanently lost a few things that I can recover.

If you really must use this add-on, make sure you BACKUP everything and make periodic local backups. I have no idea why it did this, there is almost no logging either in the floccus add-on or on Nextcloud. The documentation and support for this is pretty poor (though I do understand that it is maintained mostly by one person). I would highly recommend using something else, since this type of error is completely unacceptable for an app like this.

Maybe it works better if you self host or use only local options? I don't care to risk it again at this point.

Worked for a few weeks. Then after a Nextcloud update all bookmarks were gone.

sync with Nextcloud - NOT WORKING;
sync with WebDAV - NOT WORKING

UPD: v4.4.7 - can't push bookmarks on server - return many errors `Syncing failed with E015`. In logs private data - I send it via e-mail

Now I often use chrome and Android Firefox, but the two bookmarks and other data can not be synchronized, and the current Android Firefox can install a considerable part of the extension plug-in, after a friend recommended that I install flocus, but still can not easily achieve chrome and Android Firefox bookmark synchronization, because I must often open the computer Firefox, to synchronize data.Could you please adapt flocus to the Android Firefox extension plug-in so that Android Firefox can successfully install flocus so that more users can sync their data?

Bon module afin de sauvegarder mes marques pages en local plutôt que par mozilla

Finally !! I am able to sync my Firefox bookmarks with Kiwi browser extension. Thank you so much DEV. I was looking for such solution for a year. and finally I came to know about this robust and beautiful add-on.

Excellent addon, much improved from its earlier incarnations. I use it with nextcloud and I have not used any other bookmarks sync tool since switching to this.

Addon installation on Firefox works and login into Nextcloud works as well ... on NC "Bookmarks" is installed and works ... Floccus says sync worked all fine but nothing was synced

Update 14.10.2020: tried again for 2 hours to get it to work - no chance. Heaps of cryptic error messages but I'm ending with messed up bookmarks and have to revert to backup ...

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!
