Review summary

Users praise xBrowserSync for easy, cross‑browser bookmark syncing, privacy emphasis, and multi‑device availability. However, multiple reviewers report serious reliability issues (bookmarks reordered/lost or overwritten), conflicts with native browser sync, performance problems, and concern that the project appears unmaintained. These strengths and risks are the most frequently mentioned points.

Pros

Cross‑browser bookmark syncing between Firefox and Chrome (multi‑device support).
Easy to install/use — many users call it user‑friendly and straightforward to set up.
Privacy‑focused: marketed and appreciated for secure, anonymous syncing.
Has multi‑platform availability (browser extensions and a mobile app reported).

Cons

Appears unmaintained or infrequently updated (users note last update years ago).
Reliability bugs — several reports of sync failures that reorder, overwrite, or corrupt bookmarks and require backups/restores.
Conflicts with native browser sync (users often must disable built‑in sync to avoid problems).
Performance problems and occasional errors (slowdowns, browser unresponsiveness, platform‑specific errors).

2025-09-23	Ze*****	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.

2024-12-06	Mi*****	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.
