Are you on a mobile device or a computer? Not sure if this will help but if you scroll down to the very bottom - as far as you can scroll down, you will see a blue bar on which at the left end there is a dropdown to select "viewing style." I had that very issue on my phone and IPAD and selecting the Mobile style helped quite a bit. You may not be able to access as many style features functions but it makes reading threads much easier.
