The extension works really well! but (I never expected myself to say this) is a bit too dark (nearly everything is completely black on the sites I tested), a darkness % or colour option would be welcome

Was great until the dev removed the one distinguishing feature (the keyboard shortcut) and now it's annoying to use, requiring me to take my hands off the keyboard to un-blind myself. I guess I'll just write my own.

This isnt a "password trojan". All this addon does is add eventListeners to check for the modifier and alt-modifier keys, F1 to F10, insert and some others.

Once you press the hotkeys you set, the script will modify style.css to set all body and button colors to #222 or rgb34,34,34.

You can find all his stuff on his github (same name), hes pretty active.

3 stars because it breaks Thingiverse.com's thumbnails.
