This add-on does a great job. I think it's the best among competitors.

Вut there's a small number of sites where it's action makes pieces of text less visible. For example, web telegram: after clicking on contact A and then clicking on contact B, the name and some other text from A becomes invisible, no playing around with settings helps.

I kindly ask the author to add blacklist for sites or toggle button / hot-key.

UPD. Only when I set 'Grayness Threshold' to zero, does web telegram return to norm. But in this case the use of the add-on makes no sense.

This is a serious add-on for your eyes that let you get a more visible look with high-contrast black and white text

This is exactly what I've been looking for it makes the text and fonts easier to read. Thank you for making this! Remember to put in a paypal or ko-fi donate button so we can help you out.
