I've the same problem not able to open the links at web pages. I can retype the link in the address field to open this, though, but impracticable with long link addresses. This appear booth on my iPhone 6 and my iPad Air 2, running iOS9.3. However, deactivating JavaScript under setting->safari->advance, I can at least follow the link on the web pages. However, links received by email still freez the the email application when trying to open.
