videos "powered by jwplayer" will not load
Hi, I'm not a developer so I hope someone takes pity on me and helps me out, Whenever I run across video that will not play if I right click on it there is a logo that says "powered by jwplayer 7.10.2". I am using FF57 and have W7. Is there some FF add-on or plugin I need, or need to disable, or some default in FF that I need to set up properly in order to watch these videos? Any help will be appreciated - I am obviously not a techie person! Thank you!!
