Please consider turning on send info to Mozilla from with in Firefox before posting a question. This helps us help you. I have no info from your system that would help see things that cause issues. So with out info.............

Please try this : Turn on Clear Type Fonts in Windows https://www.howtogeek.com/howto/28790/tweak-cleartype-in-windows-7/ as there is a known issue. If is the issue great, if not please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.1 with a Full Version Installer

If issues still, Profile : Make a new one and test ...:

If is your Profile :
