Initializing a variable with undefined is equivalent to declaring a variable
without assignment. So if this is what you want to do, you can just use:

  let shown;

[wspee, 2017/01/06 14:08:51]

Done.

-        if (Prefs.notificationdata.shown instanceof Object)

[Sebastian Noack, 2017/01/06 11:21:08]

Checking for the prototype seems unnecessary here. You rather want to check for
the type, to just make sure that the property access below doesn't fail:

  if (typeof Prefs.notificationdata.shown == "object")
    ...

[wspee, 2017/01/06 14:08:51]

Done.

+        let shown;
+        if (typeof Prefs.notificationdata.shown == "object")
           shown = Prefs.notificationdata.shown[notification.id];
 
-        if (typeof shown !== "undefined")

As per the Mozilla coding style guide
(https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style...)
which is referenced in our coding style guide
(https://adblockplus.org/coding-style#javascript), we prefer != over !==.

[wspee, 2017/01/06 14:08:51]

Done.

+        if (typeof shown != "undefined")
         {
-          if (typeof notification.interval === "number")

[Sebastian Noack, 2017/01/06 11:21:07]

Same here, use == instead of ===.

[wspee, 2017/01/06 14:08:51]

Done.

           {

[Sebastian Noack, 2017/01/06 11:21:08]

For consistency, please add the optional semicolon.

See above, you should probably use typeof here.

[Sebastian Noack, 2017/01/06 11:21:08]

I suppose, we should use the "now" variable here as well.

Done.
