hi :) (then consider to not down-vote hat you like? :D) a point of open source is one volunteer (or one commercial company) wont be enough / best for millions of users and 1000s of use-cases. You guys can really copy paste the mobile URL from the browser bar. (Or even search for the desktop URL in the code, to add it there as synonym (=Code contribution) And at doubt just ask, chatgpt and or on github, and so on.

Hi! Please add the mobile URL in our github repo if you will. This is made for www.youtube since 2012 (and www.youtube changes alone required a lot of volunteering). The descriptions sais "... (+preparing mobile m.youtube)". (Please give fair feedback. We could flag it as "Misplaced bug report or support request", but prefer to keep information visible.)

hi! youtube changing is not an issue we share every day.

1. You mean a full page youtune replacement UI? 2. There currently is a CPU hungry bug only for the moment while you are changing our settings and only in Firefox.
EDIT: Blank page? why and how? Did you check the browser console before? If it is related to one of our features the will you use our github bug report form please? (I shouldn't type this 1000s of times and Firefox feedback is not meant to be bad for bug reports. It will be remove then.)
