Adobe Flash Player For Firefox Mac Os

Posted on |



The Adobe Flash Player browser plugin lets you view video and animated content in Firefox. This article has information about testing, installing, updating, uninstalling and troubleshooting the Adobe Flash plugin.

The Firefox Software Update feature does not update installed plugins. See the Adobe Security bulletins and advisories page for information about security and stability issues affecting Adobe Flash Player and other Adobe products.

If Firefox blocks a plugin, rather than seeing content, you'll see a message prompting you to click to run the plugin, such as Adobe Flash. On some sites, you'll see just a blank rectangle, and the plugin notification icon will appear toward the left end of the address bar. Compare the installed Flash Player version with the latest version of Flash Player for your Mac OS version. If the version numbers match, you have the latest version of Flash Player. Don’t reinstall Flash Player. Continue to the next solution. If the version of Flash Player on your computer is not the latest version, quit your browser.
