How can I enable blocked flash plugin on firefox?

A couple of days ago, my computer (mac OS X 10.4.11 PPC) suddenly seemed to stop recognizing that I had flash installed and wouldn't play anything requiring flash - instead a message came telling me to install it.

I uninstalled flash and the installed the latest version for my computer from the adobe website (which is 10.1.102.64).

Computer still thinks flash isn't installed and when I checked plugins I discovered firefox has blocked it telling me the version of flash I want to use is too old (even though the version I've downloaded is the latest I can use with my computer).

How can I enable the plugin on firefox so I can use flash? The 'enable' button on the plugin has been greyed out so I can't press it.

Please help - I'm rubbish with computers so please give any advice in very simple language! ( i have firefox 3.0.4)

Try to disable blocklisting by setting the Boolean pref extensions.blocklist.enabled to false on the about:config page.

Also remove the blocklist.xml file and the pluginreg.dat file in the Firefox Profile Folder.

You can use this button to go to the Firefox profile folder:

hello this should not have happened - mozilla recently uses the blocklist feature to notify users about the outdated flash plugin but not block it. you'd have to trigger a manual update of the blocklist and hope that this time the correct version is retrieved.

go to tools > web-developers > error console & copy the following line into the code field & hit evaluate:

Components.classes['@mozilla.org/extensions/blocklist;1'].getService(Components.interfaces.nsITimerCallback).notify(null);

sorry for the computer gibberish. afterwards restart the browser & see if you can enable the plugin in the addons manager again.

I was facing flash player error while playing angry birds. The thing you need to do just download the adobe flash player uninstaller and remove the old flash player after that install the fresh flash player from the adobe website. Restart your browser... This works for me.

marigolds, The Firefox 3.0.4 is rather old and vulnerable as it came out back on November 12, 2008.

The last version from Mozilla to work on PPC macs is Firefox 3.6.28 which was made EOL in April. http://www.mozilla.org/en-US/firefox/all-older.html
