I had the time and courage (after four glasses of wine) to boot Slax and try
to delete Firefox. Strange things happened. I accessed my Linux Mint partition,
entered Home/Alexandru, clicked on View, Show hidden files and simply deleted
the folder .Mozilla, as I Could not find anything else, like .Firefox.
Then I rebooted and boted Linux mint and clicked on the Firefox icon and
surprisingly firefox opened ! so in fact it was not deleted ! but without
Windows Live Search ! I launched Seamonkey from the terminal and it did open
although I deleted the .Mozilla folder !
Again, Firefox opened wuth the ubuntu webpage, not that of Linux Mint.
