Mega.nz has an add-on that is verified and firefox does not want to install it because it is not verified!

What to do to get that Mega add-on?

You can set the xpinstall.signatures.required pref to false on the about:config page to allow installing unsigned extensions in Firefox 41.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Firefox 42 won't allow this any more.
