I get a "page crashed" when I try to login to http://www.netvibes.com/dashboard
48.0.2652.0 (PGO) - Win10 x64

After entering credentials it renders the top menu bar, but before the news feed blocks appear it crashes.

Slightly related: the dark feature is there for quite a while now in the developer preview. But still it shows me a balloon "new feature" every time I go to the speed dail.

If a users ignores this balloon for weeks, he is just not interested in the feature. Stop bugging him
