missing /opt for firefox esr install

Question

wanted to install firefox esr via the package from mozilla.com and still want to. Found an guide to do so which includes to unpack the package to /opt = "sudo tar -xvjf firefox-10.0.2.tar.bz2 -C /opt". Well surprise there is no /opt in elementary loki and i really don't want to use any PPA.

My Question(s):

• does it matter where to extract the package? means do i need to create /opt?
• or is there another way? whats my best Option?

Thanks

You can extract it anywhere as long as you don't create a conflict with firefox dependencies. To be safe and for ease of finding its location, I recommend just putting it on /opt.

Just create the /opt directory manually via terminal or file manager with root privileges. Since elementary doesn't use it by default, it's safe to put manually downloaded software in it.
