Hello,

You probably activated the "Super-speed" feature (in upper right menu). When this feature is enabled, you can drag and drop only when holding Ctrl or Shift keys. You can also disable Super-speed.
I hope this helps :)
Also make sure to watch my introduction video:

Have a nice day :)

Hello,

This sounds like issue not related to my add-on at all.
Please try to use Firefox Reset to fix your Firefox:

I hope this helps :)

Hello,

I've released new version 6.6 that should better inform about errors.
Also I fixed some issues with import. But if it still doesn't work, please send me the file you are trying to import and I'm sure I can fix it in several hours.

I hope this helps :)

Have a nice day,

Hello,
There is something wrong with your Firefox, I've never seen such behavior.

Hello,

1) This is most probably due to disabled History in your Firefox settings.
There is bug in Firefox that prevents add-ons from accessing database if your Firefox / Settings / Privacy & Security / History - is set to "Never remember history".

2) Or your Firefox has broken database support. This happens in some rare cases usually on very old Firefox profiles or for users that downgraded from Firefox 57.
To validate that you can visit this demo page:
http://mdn.github.io/to-do-notifications/
This page is using same database technology as my add-on. Check the log text in bottom left corner - if you see there "Error loading database" then your Firefox has indeed broken database.

What should help is Firefox reset feature:
https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings
Resetting profile will preserve your passwords, bookmarks and other important things.

I hope this helps.

Have a nice day :)

Hello,

That's just impossible :)
But you can probably export the old ones and import them into Group Speed Dial.
See fro example here:
