On my device list I can see old PCs which don´t exist anymore, but clicking the "sign out" button doesn´t sign them out. What can I do to remove these old devices from the sync-list ?

Type about:accounts<enter> in the address bar.


Is this the button that is not working?

Thank you very much, FredMcD. I tried all suggestions you made. Sorry to say that nothing worked.

I will try to create a new sync-account. Maybe these old entries will not be there.

I have another Firefox-account, created a few years ago. Login worked and when logging an old entry out, Firefox sent an code to my e-mail. With this code the entry got deleted. But not the other old entries. Now it is the same problem as before. Nothing is deleted anymore.

Now I will create a new account.
