for example: navigation to firefox.com works instantly trying to get there from a search result https://www.google.com/search?client=firefox-b-1-d&q=firefox+forums hangs the browser. new tabs wont work correctly. I have to close the browser and start over. It will always hang again. This is a new windows 10 and browser installation (about 10 days old). I had to replace my boot drive due to hw failure.
