I'm using Firefox 66.0.2 (64-bit) on a MacBook Pro running OS 10.14.4 (Mojave). When I attempt to get an add-on, I get the message that I'm using Firefox 49.0; and I'm not allowed to get the add-on.

Hello insarta,

That is not so strange, as your system details show this user agent :

"User Agent: Mozilla/5.0 (X11; NetBSD amd64; rv:49.0) Gecko/20100101 Firefox/49.0"

To reset the user agent, would you please take a look at this
