User Reviews

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).

Recent reviews

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.

Is xBrowserSync Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

xBrowserSync requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

xBrowserSync has earned a fairly good reputation and likely can be trusted.
