Metaboli Yummy Player is not compatible with version 5.0 so I would like to reinstall a lower version, but cant find out how?

You can try this extension if you have compatibility issues with other extensions,

• https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/

If you still want to downgrade, see here:

• http://releases.mozilla.org/pub/mozilla.org/firefox/releases/latest-4.0/win32/en-US/
• installing firefox

Thanks, the compatibility thing didnt pick up Yummy. Will have to downgrade, which is a shame. Or use IE.

Try this link for version 3.1.18.

Scroll down the page to locate the Language you would like.
