Google Chrome Flash Videos Won't Play on Linux or Mac
When playing YouTube on my Chrome browser, I started getting the error: "Couldn't load plugin"
Type "chrome://plugins" in the address bar. Then, expand "Details" with the + sign (roughly top right of the page) and hit CTRL-F to find and search for pepperflash. Disable what is found and then refresh your browser to see if it worked.
The above fixed it and I can play Flash videos again. Note Chrome is supposed to have an update that fixes this as well but I have had so many proglems lately I just Disabled as above for now.
