strange cookies

Watching My Cookies I noticed the presence of strange duplicates that seem to be made by XN.

I specify that not have notifications for these sites.

F.e.:

  • sourceforge.net[xn#imap#nameaccount%40gmx.com%7cimap.gmx.com#2]

Do it is normal?

It is normal.

One is for background mail checking.
#2 is used for opened tab.

Why not use LocalStorage instead of cookie for this purpose?

Because they are COOKIES.
Cookies has expiration and this is managed by cookie manager in Firefox.
