You are running a very out of date version of Mac OS (10.7). Can your system support an update to Mac El Capitan? https://support.apple.com/en-us/HT206886
If you can, I suggest updating to El Capitan, and then update Firefox to 63.0.3 or later.
Did you try to disconnect and reconnect the monitor cable at both sides?
