Many thanks. I do not use Pale Moon, only Serpent
For me working user agent for player.pl is:
general.useragent.override.player.pl;Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.9) Gecko/20100101 Firefox/52.9
Due to the ads,scripts I do not watch through the browser. I only need to change seasons/episodes and download videos an external program. Now thanks to you I can do it
However, in order to have access to the instagram, I need to change general.useragent.compatMode.version to 56.9 and lower, because the default 60.9 only displays the camera icon in the middle of the screen - but you probably all so have, so you also have to change to lower to have access?
Or create next user agent only for instagram:
general.useragent.override.instagram.com;Mozilla/5.0 (Windows NT 6.1; WOW64; rv:56.9) Gecko/20100101 Firefox/56.9
