Is Firefox no longer reading *local* VTT files?

I have a website that has MP4 video in a HTML5 video player, with subtitles done in the WebVTT format (*.vtt). I just noticed that, when testing my pages locally on my C drive, the subtitles no longer appear on the movies. They do appear on the website (thankfully). Does this mean that lately Firefox has dropped support for local VTT files? Chrome has always ignored local VTTs, for some reason, which is why - until now - I used Firefox to test subtitles off the C drive. Note: If I link the local page to the VTT file on my website, subtitles still do not appear in Firefox. It could be something else, of course, so just need to know if VTTs are now unloadable locally in FF.

Are you using file:// links or are you using a server to access the VTT files via localhost ? There can always be restriction with using file:// links.

Thanks. Yes, I open the pages from file://. FF still loads everything else - the HTML page, the CSS, the mp4s, images, just not the VTTs. Reading the VTT files has never been a problem until now. So maybe recently FF introduced some extra "security" that's blocking VTT in particular?
