Could you please, make us demo picture? 

Hello! When does bookmarks losing and double up happen? What actions you do for this?

Please, do sync and tell us your account.

Also we need info about your OS, browser and addon version. 

Do you use any anti-virus or cleaner software?

Please, install the latest version of EverSync for Firefox. Also, if you want to use dials synchronization, use built-in Eversync in FVD Speed Dial addon.

Please, do the following:

- Right click on the Default group and select Default-option

- Then try again and let us know about the result.

Have you installed the latest build of FVD Speed Dial? We've fixed it couple days ago.

Hello! Please, send us your backup of dials.

Do you want us to increase Size range in settings?

Hello! Could you please, show us screenshot of the problem? What page that says it will not work do you see? 

Do you see this?

I think there was auto-updating of addon during the time browser was opened. We've fixed it in the latest build.
