Well, it depends on what URL you are visiting. This is an old browser, so it is quite possible there are many unsupported web sites.
I think the default home page is http://jolla.com, so this is what the browser is trying to load when you start it. Try to change the default page to something else, or try another browser from openrepos e.g. webcat.
In my experience webcat is loading up pages better that the silica browser.
