Since latest update on my Mac iOS 10.11.6 on most websites I get no actual words, only squares with question marks. How do I fix this? Maddening.

It seems like everytime Firefox does an update, it creates some kind of new problem. Often crashes, apparently, when an update is made, then on restart, it installs the update.

But all that I can live with, but not this problem where the fonts won't display actual words.

hi, you're likely seeing https://bugzilla.mozilla.org/show_bug.cgi?id=1460917 which is triggered by third-party font managers changing the location of fonts on the system on older versions of os x. mozilla is looking into this problem & a fix is scheduled to land in the next beta build for 61.

as a workaround in the meantime you could try the following: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.sandbox.content.level. double-click it and change its value to 2 or 1 and restart firefox once.
