Use this add-on from the Firefox website which back-ups all your current add-on’s than uninstall Firefox and delete all settings and preferences and install Mozilla again and install the back-up’d add-on’s, lol..simple

It is according to where you change the text size settings. If you do it by right clicking your desktop and then enlarging text size from the default size for your LCD monitor, from 100% to say 110% or more…then the pages won’t display correctly and also your program interfaces will be chopped off.
Try and run your monitor settings at 100% and if you need to enlarge text in FFox then you can override the webpage settings. See the image of my settings below:
