The Low Quality Flash extension was created with the purpose of reducing the handicap of having to use an older Mac or any other additional device that has a slower performance.
The Low Quality Flash extension is not supported or endorsed by Adobe in any way. The Low Quality Flash extension add-on does not interact directly with Adobe Flash (only with the HTML code included in the source code).
NOTE: The Low Quality Flash extension add-on is cross-platform and it works on Windows, Linux and Mac OS.
