    Like many who have commented here, I have vision problems, which makes this valuable to me.

It is terribly difficult to work with some web sites because of color problems. Bless your efforts, sincerely.

    I love the Theme Font & Size Changer. I’ve only had it for about a month, but it’s great! With my disability conditions, it is so much easier for me to see the words and fine print.

    This is a really fab product. Love that you can enlarge the font and also choose which one you’d like to use.
    The new feature I haven’t tried yet and hope that it will work in Waterfox.
    I also recommend this app to people who have trouble reading the small print that has changed so drastically on the web.
    Thank you :)
