Userscripts.org

I don't know why,I can't use the option button? I can see it,but Click on it nothing happened.
I'm using the firefox3.0.3,Is this a bug or what?>_<
Thanks for the reply.

It's most likely because YouTube changed some of the code on the website and the script hasn't been updated to work with it. You can still set options manually within the script, though. Right-click the Greasemonkey icon and click Manage User Scripts, then highlight the script and click the Edit button down at the bottom. If you haven't already set a default text editor it'll ask you for one now. Find this section of the code:

// Get the user preferences for Greasemonkey
// For other browsers these options have to be changed manually from above
previews = getValue('previews', previews);
embed = getValue('embed', embed);
hdSupport = getValue('hdSupport', hdSupport);
autoExpand = getValue('autoExpand', autoExpand);
correct43 = getValue('correct43', correct43);
autoLightsOut = getValue('autoLightsOut', autoLightsOut);
hideComments = getValue('hideComments', hideComments);
hideAnnotations = getValue('hideAnnotations', hideAnnotations);
buttonStyle = getValue('buttonStyle', buttonStyle);
autoCheckUpdates = getValue('autoCheckUpdates', autoCheckUpdates);
debugMode = getValue('debugMode', debugMode);

Comment out all of those by adding two forward-slashes in front of them (like this: //this is a comment). Then scroll up to the top of the script and set all the variables however you want.

It dosn't work at me, too.
