I've been using Firefox for Android on multiple devices for many years now. I have poor eye sight and I end up zooming in on pages a lot, but when I do that the text doesn't auto-fit to the page so I end up having to scroll side to side as well as up and down constantly and it makes reading web pages a very frustrating chore. how do I get the text to auto-adjust to the new zoom level so it fits on the screen?
