2 major problems.

1. it disable high contrast for all websites, not just the current tab.

2. When trying to revert back to High-Contrast, it doesn't work properly. You are forced to remove the extension to get High Contrast mode working again.

I couldn't use FF for many years due to the lack of this amazing extension. 🚀🚀🚀

Not working for firefox 139. Sets to "customized" instead of automatic, not respecting browser's original configuration. Seems to be out of maintenance so I have to change to 1 star.

Works great, toggle high contrast setting. Allow it to remember settings for a site would be a great addition.

Useless

Somehow, this extension degraded contrast on multiple websites when the high contrast switch was turned OFF.
See https://daverupert.com/about/ for example

This is so much easier than having to change settings on PC. All I needed was to be able to change a page from all black with white font to white with black font. This is perfect and I do not have to reset anything. :)

Switches ALL TABS to high contrast. This makes it not very useful IMO, since it would make more sense to just switch to high contrast in settings.

Fantastic!
Please add a customizable keyboard shortcut option, so anyone can bind this to every button they like

Simple High Contrast mode switcher. Perfect for e-ink devices like the Pinenote I'm writing this review on. Light on resources compared to CSS modifying addons. Open-source, code available on github.
