You appear to be using a Firefox 45.0b10 beta version and not the official release.

You can check this pref on the about:config page to make sure it is default.

• browser.tabs.showAudioPlayingIcon

Note that the Classic Theme Restorer extension has a checkbox to show or hide this icon in case you use this extension.

• Classic Theme Restorer: Advanced > [] Audio playing icon on tabs

Thanks for the reply. I don't know much about computers, sorry. I'm self taught via Google search. It seems I had missed an update somehow. But, I always use the official release. Anyway, I looked and found how to do the update. It worked. The sites where my on/off X wasn't working are all working now...yeah!!! Some sites WERE working.

Now to figure out how to save a gif file/pictures to use as my desktop background. All the gifs I save come out static. I admire anyone that understands computers. I'm a senior that started late in the game. Wish I could just tell it what I want...like Star Trek....lol. I do love Firefox. Thanks again.....:-).....Becky

Keep in mind that telling you whether the user name or the password is incorrect would be a security risk as this would allow an attacker to find out whether a specific user name exists on the server.
