I have a lot of trouble reading FR on my iphone too.
I have multiple browsers on my phone it is hard to read on all of them .
Settings > display and brightness > text size
to make your text larger on your phone
If the text is still to small on FR
you will probably have to do what I do and that is use your fingers on your screen to zoom in .
(it’s a pain and I hate reading this on my phone)
Yes, of course I do zoom the text bigger with my fingers but that would mean scrolling left to right for every single line of text. I can’t be the only one trying to creep on an iPhone. There used to be certain browsers that you could enlarge website fonts to work within text boxes. Is there one?
I wish FR would be updated for the 21st century.
