Hello. English is not my native language, so I watch all TV series and cartoons in English with subtitles in my native language. Everything was fine until, at some point, one of the most accessible players that provided subtitles stopped displaying them. I thought that the player had broken or that some technical work was being done. But after a week, nothing had changed. Then I downloaded Chrome, and the subtitles display perfectly in it. It is in Firefox, specifically this player, that subtitles are not displayed. Other players display subtitles, but they are either unstable or constantly crash. Therefore, they are inconvenient to use and spoil my user experience. In general, if you have any tips, I would be grateful.
