Another indispensable add-on Rated 5 out of 5 stars

Of course there are so many situations one wishes to dim the opacity of a website. Highly recommended!
I tested this add-on for two days (48 hrs). Maybe because of the opacity I had problems with one small detail. Standard the opacity is 60% but where can you vary this percentage?

This review is for a previous version of the add-on (0.1). 

Opacity options

Hi, thanks for the review.
You should be able to vary the opacity in the options screen. In my browser it's at Tools - Addons - Dimmer - Options.

I've updated the listing to include a screenshot of the options menu.
