Unfortunately, here also Firefox + uBO (non-lite) and I get the delay. Or rather, I got the delay until I applied the latest update to the Quick fixes filter. That seemingly took the delay down a little but not completely (don't know if it was for that specific issue) I then applied a rule to My Fitlers that @nicolaasjan provided here. It worked for me--now any YouTube page will load almost instantly for me, like in the olden times. Does not affect me in Brave for some odd reason--Brave has never given me any YouTube trouble to date. So I don't know what the deal is with Firefox + YouTube. But for now: it's OK again.

The latest such incident seems to be happening right now as there are several user reports online which suggest that YouTube is being intentionally crippled on Firefox and is being made to load up slower.

At first glance, if your internet connection is fine, it will seem like the issue could be related to performance and hardware optimization on Firefox's behalf, perhaps poor or sub-optimal hardware acceleration support or the improper utilization of the available processor threads, among other system resources. However, users found that the issue—a 5-second delay when loading a YouTube video on the Firefox browser—goes away when YouTube is tricked into thinking that it is running on Google Chrome using a User Agent switcher.

YouTube admits:
YouTube blames ad blockers for slow load times, and it has nothing to do with your browser
Here is the complete statement sent to us by a YouTube spokesperson:
To support a diverse ecosystem of creators globally and allow billions to access their favorite content on YouTube, we’ve launched an effort to urge viewers with ad blockers enabled to allow ads on YouTube or try YouTube Premium for an ad free experience. Users who have ad blockers installed may experience suboptimal viewing, regardless of the browser they are using.
