Was having trouble getting uBlock Origin to hide the big ad blank space, this solved my troubles!

gregbanks2 is right … the applet used to be reliable … now, ymhap has stopped working. currently using firefox(64bit) 51.0.1 version … since the applet stopped working, now ⅓ of the screen has been taken away. can you pls fix? both firefox and ymhap were freshly installed today.

thanks for your courtesy, piyush.

until late Jan17 Firefox update.
