What does this mean for me? You will always be able to play your favorite games on Kongregate. However, certain site features may suddenly stop working and leave you with a severely degraded experience.
What should I do? We strongly urge all our users to upgrade to modern browsers for a better experience and improved security.
We suggest you install the latest version of one of these browsers:
Try
typing into the url bar: about:config
search for: dom.ipc.plugins.sandbox-level.flash
set it to 0 (or 1)
...and then restarting the browser.
