Google is fussy about copyright stuff and browser extensions. I used a dash in the name to get around their copyright rules – they caught me. Google owns youtube.com, as well as you-tube.com apparently (even though it doesn’t resolve, it goes through google nameservers) – they don’t own utube.com (Universal Tube & Rollform Equipment Corporation does – I don’t think they’ll complain about my browser extension). So I think this new name will be OK (hopefully). I just want to mention that I am just trying to make searching youtube.com easier and more convenient – nothing more. I’m sorry if this caused my users or Google any inconvenience or problems.
