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.

Funciona excelente! funciona en un 98% de las paginas que visito, hay algunas que existe algun error, pero en su mayor parte funciona muy bien.

best extension ever for dark mode. its works on all websites, you can disable/enable specific websites, you can adjust the colors and its open source!

how to bypass protected pages? change brightness in firefox homepage only for about: key dont work!

I like it !

very good +

What a piece of shit this extension has become! Completely crashes Firefox here, every fucking day, stops browser from accessing internet if I am on VPN, it never works I have to restart firefox constantly if watching videos, whatever. It is useless!

Change colors pretty well, but it causes a lot of pages to load very slowly, in stages, and in the meantime sometimes it'll be half dark, half white, stark eye-straining contrast.
