I'm on Firefox 34.0 on a Windows 7 laptop. Up until recently I had no trouble viewing videos on YouTube. I would enter "youtube.com" into the browser address and it would take me to http://youtube.com. But now it takes me to "http://m.youtube.com/?", which appears to be a mobile YouTube viewer. And when I try to open a video there I get this message:

"Firefox doesn't know how to open this address, because one of the following protocols (rtsp) isn't associated with any program or is not allowed in this context."

This just started after the latest version of Firefox uploaded to my computer. Why can't I access the normal Windows version of YouTube anymore?

This problem has been fixed. I rebooted my laptop after clearing my Firefox cache and deleting all cookies. Once my laptop was rebooted, I opened Firefox and now I can access the regular YouTube site, not the mobile site.
