I have just installed "Opera" browser which I thought would allow me to install an App called "Marine Traffic" onto my computer. It seemed to make changes to my default browser which is Firefox, so I re-installed Firefox. Now when I click on Firefox it comes up with a search bar but it is not the usual search bar but a largely blank screen with just a search bar in the middle. It does come up with an option at the top for another search session and when I click on that it is the normal Firefox browser screen. Can I get rid of this first strange blank screen with search bar? Mark
