This extention is helping, but the downside is I can no longer see pictures on social media! It's just a blank space where pictures should be. Doesn't even show alt text in its place.Not sure if this is a bug or intentional.

I am dyslexic and obsessed about finding the right font to read on the web without which it’s very difficult for me to pay attention. Until I discovered this app I used to convert the web pages to epub and read it on an epub reader just because the reader supported the fonts I was comfortable using. That was enough of a struggle as it is and was not practical at all as converting every web page was too much of an effort. This app is quiet straightforward and simple. Once I install and update the font settings I just have to do a one time setup on safari and voila ! It automatically updates the web page with the font right on opening. Doesn’t impact any images on the page or user experience whatsoever and works quiet seamlessly. I am very happy that the developers have come out with this and I don’t think I can imagine browsing the web without it anymore .

Very poor experience

First off the app doesn't actually work properly. It seems to change the body font but misses out if a font is specified more specifically.The app has an extremely bad user interface is feels janky. Even worse there are terrible dark patterns that make close buttons and other elements practically invisible in order to get you to buy in app purchases. Even worse the prices are ridiclous and recurring by default – £0.99 per week for something that doesn't even work? No thanks.I uninstalled the app minutes after installing it – don't even waste your time!
