Older eyes? You need this

Well-designed tool which makes it easy to tune websites for legibility (and easy to turn it off for the sites which refuse to play nicely).

How to upload custom fonts

So far the app works perfectly, it changes fonts, but is it possible to install custom fonts?

Thank you for the great feedback

Suscripción

Cambiaron a un modelo de suscripción, no entiendo el por qué. No hay forma de comprar la versión de por vida, sin mencionar que el precio de la suscripción anual es excesivo para lo que hace.

Works only intermittently and not on all fonts on the page

I installed this extension to increase the size and change the font of letters in my gmail inbox in Safari. It only worked intermittently, and sometimes, for some entries in the inbox and not others. Turning the extension on and off in Safari sometimes worked intermittently, as did closing Safari and reopening it, but I could not get the font changes to remain stable.
