Can you add an option to invert the colors of images?

Simply one of the BEST add-ons for Firefox!

no funciona y me es muy necesaria

Although my use of this app was no problem only my zendesk application somehow changed color to faded white and letters no color thus invisible.

My eye sight is pretty bad so that I was using this but now I am forced to move onto other app which can change the hues on screen accordingly. inquired through Twitter and through email to no avail. You did not respond. You should have responded to my inquiry.
