It's good, the only downsides are that it hasn't been updated since 2020, and it doesn't work with the mobile version of Firefox (+ forks).

SENSACIONAL!!! Extensão perfeita! 👏👏👏👏👏
Funciona em todos os navegadores e ainda tem uma versão em aplicativo para celular muito útil.

RECOMENDAÇÃO: Permitir que o usuário escolha os favoritos destacados na tela inicial do aplicativo em vez de exibir os últimos adicionados.

I just wondering way how to sync favourites between internet browsers... didn't expect it will work so quick :) Amazing Extension !!!

Ottima estensione. Unico pericolo: interruzione del supporto/sviluppo.

I used to love this extension. It was BY FAR the best solution for using multiple browsers to sync over all devices.

In the last six months or so, it has quit working as well. Now, it is impossible to organize because it keeps re-syncing and overwriting changes made on the browser. In my Linux installations, I now get an error message for which the meaning is impossible to track down and it doesn't sync at all.

The best bookmark synchronization add-on you can find. Secure, anonymous and easy to use. The theme could use an update.

Is this still maintained? The last update was four years ago.

The syncing between Firefox and Chrome worked pretty well, but some weird stuff happened. I had backed up my bookmarks before use. The Firefox Places database got a cluster of new separators in the Bookmarks Toolbar, and lost some others. (This may have something to do with the fact that Chrome does not have separators.) Firefox Bookmarks Manager stopped working - I could not add or delete anything. Restarting Firefox was not helpful, though the cluster of separators was reduced to one. I opened about:support, and verified the integrity of the database (there's a button far down the page); the database was intact, but the problem remained. I then tried clearing the Startup Cache (This button is at the top of the about:support page.) Bookmark Manager started working again. It's a little inconvenient for my intended pattern of use. I have to log out of the accounts with Mozilla and Google to ensure it will work properly. That's not compatible with other uses I have for Chrome, so you have to shut down the native sync functions, run xBrowserSync, and then shut it down and turn the native sync functions back on. I'm not sure I want to keep using it.

Install/setup well done worked smoothly considering crossing several different browsers. Privacy seems important to dev team/Company which other companies use as a advertising tag line. Hopefully the positive experience continues with daily use.

Keeping my bookmarks, history, and tabs synced across devices seamlessly. It's user-friendly and reliable, ensuring I never miss a beat when switching between platforms. If you value organization and convenience, this extension is a must-have for staying in sync without a hitch.

It used to work well, I was trying to recommend this to my friend. But one day, it mess up all my bookmarks. I don't know why, it just blows up some bookmark folder after a sync operation and the orders of the bookmarks are all in chaos . I have to disable the plugin and restore from a backup. Please fix that(bug happens in firefox), you are the first one I used that perfectly sync my bookmarks between multiple chrome and firefox in multiple machines.

so far this extension has worked beautifully!

Was hoping this would help me sync two PCs both using Firefox and Chrome. Bookmarks disappear when i'm saving or rearranging them and then the browser becomes unresponsive for a while. I followed all the guidance and also turned off internal browser sync but to no avail. Thankfully I'd already read the comments so took backups every day. All-in-all it was a waste of a weekend and change. Uninstalled.

Perfect for synchronizing bookmarks between several different browsers. Very easy to use.

Perfecto para sincronizar los marcadores entre varios navegadores distintos. Muy fácil de usar.

Negative: Doesn't work on Mobile. Positive: Properly synchronizes between Chrome and Firefox (on desktop) with both native bookmark sync functionalities enabled.
