It works just like Xmarks. I got the extension for FireFox 60 and for Internet Explorer and uploaded my bookmarks from FireFox to Eversync, and then downloaded from Eversync to Internet Explorer. Worked very quickly both uploading (650 bookmarks) and downloading. No duplication at all like some reviewers have reported. I can't tell that it is any different than Xmarks. Love it.

Two great features: access my links on every device and SpeedDials for frequently used links!

The interface is clean and easy to use. Basically it does everything I need it to do without me worrying about losing my bookmark data. I really love it!

For free stuff, this's 1 of the best

Not ready for prime time!
Now is the time to fill xmarks shoes, but this has a long way to go. Duplicates over & over. Time consuming to clean up.

good option to forget Xarks

This extension wil not install. Every time I try, I get the message "Only available with Firefox; get Firefox now." But I am already using Firefox, latest verson, and nothing I do gets me to the eversync istallation page.

good stuff

....

Kool. App. I just hope it works

In Firefox 59 x64, I cannot even do the initial sync,
I always get "Sync Failed"
(in Chrome it worked for the initial sync)

不會自動同步？

Finally it works on Linux again!

So far so good.
I am missing one feature: having profiles (like in xmarks) for work and home. 5* if you implement profiles.

Well, for syncing between different browsers, like Firefox and Chrome, it seems to work. Sort of. VERY annoying that at least the free version will not sync separators, though, so it would be stupid to use this to sync, say, from Firefox to Firefox, for which the Firefox built-in sync is vastly better.
