Recently I upgraded to Safari 6.0, on my MacBook Pro using 10.7.4. Trouble ever since. Most of the time the back arrow in the upper right-hand corner is grayed out an non-functional. Worse than that, no video will play. It keeps telling me a new version of Adobe Reader is available. I download it, and in a day or two it tells me that all over again. Got o Youtube, e.g., and the screen is bland with the message "Blocked Plug-In." On Google Chrome, videos play fine. Driving me sane!

    Safari 6 blocks outdated versions of Flash which is required for most YouTube content which is why you are seeing the Blocked plugin dialog.



    Uninstall the old plugin here > Troubleshoot Flash Player | Mac OS


    Then reinstall new here >  http://get.adobe.com/flashplayer/


    Then open System Preferences > Flash Player then select the Advanced tab. Click: Delete All


    Quit and relaunch Safari and try a video.


    If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.


    And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to:  Open in 32 bit mode  is selected, deselect, quit then relaunch Safari.

    Most of the time the back arrow in the upper right-hand corner is grayed out an non-functional


    From your Safari menu bar click Safari > Reset Safari. Select:  Clear History  (that also empties the cache)


    Deselect the other boxes then click Reset.


    If that didn't help the back arrow issue, open the Finder. From the Finder menu bar click Go > Go to Folder


    Type or copy / paste:   ~/Library/Caches/com.apple.Safari


    Click Go then move the Cache.db file from the com.apple.Safari folder to the Trash.


    Quit and relaunch Safari to test.

    Delete "_Flash Player.plugin" and your problem will go away.

    Wow, that turned out fuzzy...like the 7-11 videos they show trying to identify robbers. Let's try it another way...













    file://localhost/Library/Internet%20Plug-Ins/Google%20Earth%20Web%20Plug-in.plug in/














    That's better.  TnT

    No problem.  See above about _Flash Player.
