Open Firefox, go to the FVD Speed dial options, and copy the url that appears : (For me: moz-extension: //9800b16d-db28-4293-a176-ac60085324c2/options.html)
Then replace "options.html" with "newtab.html" Which give : moz-extension: //9800b16d-db28-4293-a176-ac60085324c2/newtab.html
Open the options of Firefox this time, go to the Home tab, choose as homepage "Custom web address", and paste the URL copied previously (moz-extension: //9800b16d-db28-4293-a176-ac60085324c2/newtab.html)
I found the solution :-)
