On both desktop and mobile Firefox I am seeing a white square in the bottom right angle of each image. As for Pale Moon (I use the specific fork of Greasemonkey there), I cannot seem to access the settings like I can with Tampermonkey on Firefox. Also, I am having trouble reading text when I combine dark theme of this extension with dark theme of the site.
