DO NOT USE, NOT UPDATED IS 3 YEARS WILL LOSE YOUR DATA ON CURRENT FIREFOX VERSIONS. SEE GITHUB APP ISSUE 265 FOR FULL DETAILS.

I used xBrowserSync for extended period and was very happy with it ... until it started to delete my data. Thank god I had taken backups or I would have lost 100s of bookmarks, many very hard to find tech publications and KBs that I could not simply google and find the information again. This used to be great but last update was April 2020 and the issue is supposedly going to be fixed in version 1.6. The problem with that, version 1.6 fix was supposed to come over a year ago but 1.5.2 has been active version for almost 3 years now. DO NOT USE IF YOU VALUE YOUR DATA.

Buggy. Kept deleting all my bookmarks and leaving me with zero bookmarks.

Thank god I created a backup before I installed this buggy extension.

Muy buena extensión, funciona como dice :)

Best cross browser bookmark sync there is

This app is really useful. Just make sure you create backups as the developer cautions multiple times during setup in case you run into issues.

I was genuinely excited for the item of secure, open source bookmark syncing between browsers.

But a combination of the recently reported issue #328 (Not syncing completely) and bug #265 (Local data refreshed, redo previous unsynced changes) which remains unfixed 9 months after it was reported renders this product completely unusable.

I suspect if it works for you then it's tremendously useful, but my own search for reliable bookmark syncing continues.

Must have add-on.
Excellent. Works great. Thanks a lot.

This addon completely broke all my bookmarks. I shifted half of my bookmarks to another folder. It said client out of sync or some nonsense and completely messed up the places of all my bookmarks. Would give 0 stars if I could. Reported to firefox.

I'm always trying different browsers, this is perfect for taking my bookmarks everywhere, thank you.

Works great when you need to sync across different browsers.

This add-on is the bomb. seamlessly sync between chrome and firefox.

It looked great, but there is little or no support on mobile (only app, no native support via mobile browser plugins). I had a continuous battle with my bookmarks, they were each time jumping back in time (lucky i made a backup).

This plugin is promising, but needs a lot more work. For now i'm signing off and go back to EverHelper

This addon make all my bookmark keyword disappear.

Works great! I use to sync bookmarks between Firefox and Chrome.
