apt - is there a deb package to install firefox ESR? - Ask Ubuntu
Played with this. There is no folder called OPT in USR/LOCAL, and I can't make one. Where else can I stick the file?
I changed the version number, and got as far as put it in OPT via terminal. At least Windows asks if you want to create a directory. So I either need instructions on how to get the OPT directory in USR or find another place to put FX.
