This add-on is super helpful in working and free time, especially when I have a hard time focusing on large blocks of text, so much so that I'm going to be using it for the foreseeable future. The best part is that it doesn't cost anything like the original Bionic font. I don't believe accessibility should be something you pay for. The only issue I'm having is that it ends up having an effect that doubles up text repeatedly on Chats with sellers on Etsy and Assistants on banking websites and the like, though I'm not sure why.
