No problems here: Waterfox plus usual privacy oriented addons then Hooktube replacing Youtube. Might seem excessive but works like charm.

Just a heads up—HookTube's homepage (at least for the moment?) is very NSFW.

Warning: Hooktube link is NSFW. 'Sensual massage' thumbnail on the frontpage...

Just checked, you're absolutely right! I always use the redirector addon rather than going to their homepage though and it has been SFW so far.

To all, I can't edit anymore my post to delete it, so just forget about the hooktube address; as others reported it's definitely NSFW while the redirector Firefox addon is safe. I apologize for not checking it before.

That seems hard to believe as it would imply that they have code specifically to cripple the Firefox experience. It's probably at worst that they intentionally don't optimize their sites for Firefox and not actively making it worse.

I think it's more the case of enhancing the Chrome experience and not doing anything to deliberately impact firefox.

That is the same as what I suggested. Which would mean that simply changing a user-agent can't make anything run better on firefox.

Google does a lot of UA sniffing, and serves different sites to different browsers.

The sites served to non-Chrome receive less QA resources, as far as I can tell, and are often buggy in various ways. Simply spoofing the Chrome UA in Firefox on Android can often get you a site that works better (in Firefox) than the one served to Firefox by default.

Sometimes this happens on the desktop as well, they optimize for the latest Chrome and the "latest" Firefox ESR - so here we are, Chrome is the reincarnation of IE6'6'6 the definition of evil in the software world.
