used on Firefox and Chromium.

I was wondering if there was a reason for making the database a binary file, why not csv / json?

my thinking is it's already on your dropbox, so it's safe.

also for syncing, would be better if it merged the bookmarks by looking at the domain and then removed duplicates.

Outstanding, I've been waiting for this for years. Thank you Greg! This is perfect. V1.0 to me.

The best replacement bookmark tool for the xmarks after the xmarks stopped service

The extension is brilliant and does everything I wanted it too, unfortunately (especially as I just re-installed Windows) the add-on download keeps failing.

Better than Xmarks ..!!

This is a fantastic way to share Firefox bookmarks between PCs/laptops. I'm syncing betweek 2 x Linux and 1 x Windows laptops automatically with no problems at all - definitely doesn't feel like alpha software. Really hope development continues.

syncmarx is one of my most important extensions, which I use every day. When I had problems, Greg was very helpful and we were able to figure out the problem and solve it. Sometimes there are hiccups and the bookmarks double or are scattered everywhere. Then I go back to another browser that hasn't synced yet and force push / force pull to get it right again.
syncmarx solves a major problem of having a self-controlled, cross-browser and cross-platform synchronization solution for bookmarks. I can't wait for version 1.0.
@Greg: Thank you for an engagement, I really appreciate your time and energy.

X-marks abandoned us... Syncmarx picked up the sword!

Not sure 'why' this is not a recommended addon by Firefox? I looked high-and-low after X-marks died for an alternative. Firefox bookmark sync failed too often. Tried and older version of X-marks that allows you to setup your own server for the sync... FAILED.

Then I somehow came across this extension and it's worked flawlessly! No matter if I'm using two browsers not of the same version... it works.

Some reviews say:
*They are having issues with Chrome. Why are you complaining about a Chrome issue in a Firefox venue?
*I don't have a Dropbox account. It's FREE just get one or use Google Drive!

The only improvement I'd like to see is the icon looks like popcorn and it's could use an increase in size and something more noticeable when it's syncing.

I just left a donation and want to say BIG thanks to the developer.

Excellent app ! Efficient, easy to use. I'm using it on Firefox 70, Chrome 78 and Edge Chromium 79 (beta) on windows and mac.

Could I ask if the browser history could also be synced in the future ? That would be even better as I would not even need to use a chrome or firefox account !

Thanks for this app !

It works simple and with profiles.
Really great to see this.
Can work with Dropbox, Google Drive and Box.

Can be synced by hand, automatically every x minutes etc.
Works great (used it now for about 2 months).
I use it on 4 machines and 2 are constantly running (24/7) and still it does not make a mess out of the favorites.

And best of all, no website login, monthly fee etc. needed.

Good job

It works. But needed something that could also sync the browsing history. any suggestion?

Wow, finally a great bookmark-syncing add-on, everything works perfectly. Thank you!

Developer: Is it possible to merge 2 profiles (example Firefox and Chrome that are merged together), without messing your original bookmarks?!
