The only bookmark synchronization tool that's worked for me with the multiple browsers and OS that I deal with.

Great tool

This add-on works great! I have been looking for an extension like Xmarks for several years after it was shut down by LastPass and this does the job well. It takes a bit of time to set up, but--once it is running--it is amazing. I am able to easily sync between Firefox (and branches), Chrome, Edge, & Brave across two different profiles. Synchronizing with Opera (because of its different structure for bookmarks) ended up making a bit of a mess. Strangely, on Brave, it took what was on the bookmark in every other browser and put it into a folder with folders for other bookmarks all in the bookmark bar. While that one wasn't perfect, having all my bookmarks everywhere is great. Even the mobile app allows for two profiles, which keeps the phone in sync as well.

It would be even better if they would make an extension that would install into Firefox mobile.

It worked fine at first, but then it just broke half of my bookmarks.

Does a great job! Keeps my bookmarks synced between Edge, Firefox and Chrome on multiple computers. I just wish this worked on Firefox Mobile as well.

I was using xBrowserSync, since it stopped working on my Chromebook, I changed to Floccus. It syncs flawless on Firefox, Brave and Chrome using Google Drive.

I have around 3000 bookmarks. After restructuring them this extension uses 100% of one CPU core and looks like it hanged (nextcloud backend). Also I can't cancel sync.

ok

Floccus is a live saver for me, works like charm.

I've been using Floccus for many years. Given its versatility across different system platforms and browsers, it's an ideal option for bookmark synchronization.

Best bookmark sync utility for professionals, no ads, no bullshit subscriptions, just use a github repo and sync between multiple different browsers even on different machines.

Great extension to sync bookmarks with different machines and have a full backup in your nextcloud (safe from all GAFAM and Mozilla Foundation that spies on your data now).
Thanks for the great work :)
