"Thanks for the review. This can be achieved from the Options panel. Clicking Add-on Bar icon will provide the Options panel."
I'm not seeing it, I'm guessing I misunderstood and am looking in the wrong place? 5* for replying btw :)
You need to activate the Add-on Bar to see the Youtube High Definition icon. Make sure that you have a tick on the option of Add-on Bar which is available in the
View > Toolbars > Add-on Bar
path in the Firefox menu.
Let us know if you need further help.
