I am running Red Hat Linux Workstation with Gnome3. In Firefox i have an issue with watching video streaming and videos in general (Youtube, Webex, Company's livestream events). Video starts normally and after some time (up to 1 minute) - video just stops but audio continues. I already refreshed Firefox, did a cleanup of cookies but nothing changed. I also tried to disable hardware acceleration, also nothing changes. I tried different browser and it works perfectly in Chrome. Really want to have my Firefox to be only one browser I use so i would like to fix it.
