As the subject suggests, links of the type "youtu.be" (Sample : https://youtu.be/pBI3lc18k8Q) are failing to open in firefox while other browsers can easily redirect it to standard youtube.com hostname. Even firefox android works fine but not on Windows PC. Many solutions (like modifying browser network settings, turning off proxy, dns over https, about:config changes) didnt work. Even a fresh firefox install fails to open this link type. This needs to be fixed ASAP as most of the youtube links are nowadays shared in this shortened format and such an issue would prevent newcomers to switch to Firefox completely(I am one of them)
