I've been using Chrome since someone created an AdBlock plugin for it. I love the browser, but the latest version of Chrome broke my ability to debug Flash and Flex applications using the debug player. This also kills the ability to use the Flash Builder Profiler. The fact that Chrome silently updates itself made this one of those "WTF" moments, since everything was working fine yesterday. It took me a while to track down the problem, so I thought I would save anyone reading this the pain.

It looks like this was caused by having their built-in Flash player enabled by default in the latest version of Chrome. The browser seems to want to use this version of the player even if you have the real Flash debug player installed as well! Luckily, the fix is simple (if not obvious): point Chrome at the URL "about:plugins", locate the built-in version of Flash player in the list, and disable it. Make sure you have the correct debug player also listed in the plugin list and that it is active. Restart Chrome and you're good to go.

    Thank You for posting! I was just having a "WTF" moment myself when I saw your post.

    There is also a setting in Preferences > 'Under the Hood' > 'Content Settings' button > Plug-ins which toggles "Allow / Do not allow websites to use plug-ins".

    Somehow that was set on mine and it was a pain the rear find out why flash still was not loading.

    For me, Flash was loading fine, it just was not loading the debug player. I even went to the Flash version test page and it told me I was not running the debug player, when I knew for certain that it was installed, which just made the problem even more bizarre. After disabling the built-in Flash player, the version test page correctly shows it as the debug player. Thanks for the info about the Content Settings though, it may help others in case disabling the built-in player doesn't completely resolve the issue.

    AdBlock under Chrome just unshow content loaded into browser.
