When I open a new tap Firefox tries to open a non existant address how can I change this please


When I try to open a new tab I get this: Server not found

         Firefox can't find the server at www.[r;;iåvÞyevq¾qîx»òki.com.
 Check the address for typing errors such as
   ww.example.com instead of
 If you are unable to load any pages, check your computer's network
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web.

Hi Tylerdowner. Whilst you indeed solved my problem perhaps you can help again as when I open a new tab I do not get my home page but a mixture of 9 of the last pages I have been to. Can I set it so that I just get my google home page? Thanks for any help you can give. Les

Follow the directions I gave you before, but instead of clicking "reset", click "Modify". Put in www.google.com

Solved again. Many thanks you are a diamond
