Hello,

It just might be Firefox causing the problem. If you search "Can't change youtube video quality" up on Google, people seem to have problems with different browsers.

Yeah, I already did several google searches and their solutions didn't help. (log out, clear cache)

Have you tried logging out of your entire Google account?

Or, you could remove the cookies, this may help too.

• Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

Yes, as I said, i already did that. (log out of google account)

I also already say that option to remove cookies but I can't find it.

Firefox>options>privacy...then I can't find "cookies.

Where I've highlighted is where you clear cookies.

That doesn't appear for me.

I just see, "you may want to clear all current history." Nothing about cookies. I was going to post a "print screen" image but...well I'll do it.

Edit: Never mind, when clicking on it it has an option to delete cookies so I deleted them.

Regardless, it didn't do anything. I still can't change video quality for youtube videos in firefox.

Are you using the latest version of Firefox?

1. Using latest version of firefox; I automatically update it.

I don't know what's wrong. It was working a few hours ago. The only thing different is a new keyboard I just plugged in an hour ago. Since then it hasn't worked in firefox.

Now nothing is showing in youtube. Stupid flash won't play. I think I may just switch to chrome; all these issues with firefox.

I don't know how a keyboard would cause this problem.

How about giving this a try?

Reload the webpage while bypassing the cache using one of the following steps:

• Hold down the Shift key and click the Reload button with a left click.

OR

• Press Ctrl + F5 or Ctrl + Shift + R (Windows and Linux)
• Press Command + Shift + R (Mac)

1. I manually updated firefox and now nothing will show in youtube. I'm just not going to screw around with it anymore. I'm going to switch to chrome now.

Ok, if you have any more issues, feel free to ask again :)
