After upgrading the operating system on my MacBook to OS X Snow Leopard I noticed that the Drupal 7 CSS style .element-invisible is no longer being recognized correctly.
Elements styled with .element-invisible should be invisible to all but screen-reader users, and those browsing the web with CSS disabled in their browsers.
I have been using a MacBook with the VoiceOver screen-reader for a little over a year now, and have recently upgraded the operating system to OS X Snow Leopard. Another thing that I have been doing for about a year is complaining that the Mozilla Firefox web browser is not accessible with the VoiceOver screen-reader.
