Default shorcut conflicts with youtube shortcut, and can't change default shotcut key

[franz-ka]

Hello,

When I watch a youtube video and press Alt+J it goes backwards 10 seconds in the video i'm watching, it doesn't use this addon's functionality.

Also I don't know how to change this addon's shotcut key. I've searched in the addon's preferences, in about:config and in my browser settings and haven't find anyplace where to change this.

Thx!
