the new firefox link is:-
{
https://www.mozilla.org/en-US/firefox/new/
}
if main menu not founf on your sistem then run :-
{
apt-get install alacarte
(to install main menu)
}
1) you need to download firefox latest version from above link
2) then you need to remove old firefox using apt-get remove firefox-esr
3) extract and move latest firefox into /etc folder
4) install mainmenu using '
apt-get install alacarte
command
5)open main menu and create new item and in command field
