The addon works fine for its intended purpose, but on some websites it actually completely breaks site functionality.

Examples of things not working with this extension enabled: logging in using BankID on dnb.no, merging pull requests and syncing branches in Bitbucket.

It took me quite some time and some tickets with customer support of various services to figure out the root cause for these issues. Please fix the plugin so that it doesn't generate security errors.

This addon has serious issues. I keep finding that it injects weird code into websites just by the addon being enabled, even if I'm not using it. This results in websites breaking. It's a helpful tool but the addon is annoying to have installed.

Doesn't have nearly enough options. Would like to see Protanomaly, Deuteranomaly, Tritanopia, Tritanomaly, Achromatopsia ,Achromatomaly, and a Low-Contrast option.

It also inserts some weird copyright text into text editors when I'm trying to send messages on my website
