Ugly effect

doesn't work

made me unable to read most text on websites and made lots of buttons look very weird. would not reccommend.

have you discarded the js before the exchange with the websites I visit? Or are you giving my data to them without them to ask for? ... I am gonna check it now, but I have HIIIIGH DOUBTS you've done this to protect user intellectual rights

some pics invisible...

not working properly

Extension either doesn't darken a page, or will darken it and remove all text and images. Pretty useless extension. Don't download.

On LibreWolf this addon blacks out all colours on G Calendar and MS Office online, which I badly need for my work.

blacken the whole page including text

Does only allow to exclude websites, while I want to use it on one specific website
