Love this homepage, very versatile. Only thing that would be nice is the ability to change the search bar to use something other than Google/DuckDuckGo/YouTube. Being able to set the search engine similarly to how Firefox lets you customize it would be a great feature.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Cobalt - New Tab requires a few sensitive permissions. Exercise caution before installing.
