Cannot click the "Option" Rated 4 out of 5 stars
I'm using the Firefox 13.0.1,
Sometime I open a lot of webpages, so one row is not enough to me.
When I want to open "Option" and change the number of row,
the system shows some strange message
I capped those message as photo,below is the link
Expect that problem,
it is a great Add-on
I especally like it's group in colour function
Please download the latest version at
