Did I bounce Firefox? Meaning, did I restart it or stop using it? I did restart it but it didn't help. But I found the info about that Clipgrab downloader and it works just fine.
Sorry.... "Bounce": This is "slang" for stopping and restarting anything on a computer. Even the computer itself.
"Bounce Firefox = stop it and start it up again"
(this term is from the 1980's so I am just showing my age)
Again, I apologize for my assumptions.
