Fórum podpory Firefox

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.

Gibberish appearing in AOL & Yahoo email, not in gmail. Started after FFox 60 update. Does not appear in other browsers. Did not appear in FFox before 60. Have not updated or otherwise changed any hardware or software recently before or after FFox automatically updated itself couple days ago. Images are attached. Couple years back this was happening in Safari and Chrome but not FFox. That is why I switched to FFox. Since later upgrades, Safari & Chrome no longer display gibberish. All forums I went to had no answers not even tech support. So I stayed with FFox. Don't care to go back. Has always performed smoothly. But if this new glitch isn't fixed very shortly, I'll go back to them. Going forward with new upgrade only to go backward with text displays. Any suggestions or solutions are welcome... thanks much

Firefox updated and is now unusable. I'm on OS X 10.10.5 and have a font managing application FontExplorer X Pro 3.5.4. I uninstalled Firefox and deleted it from my Library. Then reinstalled it, but still have the same font rendering issue.
