For the past two days, only with this browser, CD, I have not been able to see some of the replies to posts on my Facebook. I made one post public to check it out from a separate account using Mozilla, and lo and behold, there were the invisible comments.
If it cannot be resolved, will go back to Chrome, which I left due to yet another Facebook related bug, where I was unable to “Like” any pages, only comments.
Will live with the lesser of two evils.
