I'm not sure where that link leads, but you should be able to get Flash from the following page. Make sure to uncheck any unwanted extras Adobe might try to include.

http://get.adobe.com/flashplayer/

Note: If Adobe's site doesn't say:

Your system:
Windows 64-bit, English, Firefox

Then use the link "Need Flash Player for a different computer?" to get the version that works with Firefox (the "other browsers" version)

Try the directions in this article, under Updating Flash:

• Flash Plugin - Keep it up to date and troubleshoot problems

If that doesnlt work then see:

Just to be sure, make sure you are installing the 32-bit Flash as you are using 32-bit Firefox on 64-bit WIndows.

If Firefox previously disabled Flash because it was an old, vulnerable version, you might need to manually re-enable it after updating. You can do that on the Add-ons page. Either:

• Ctrl+Shift+a
• orange Firefox button (or Tools menu) > Add-ons

In the left column, click Plugins. Then look for Shockwave Flash toward the bottom and change its status from "Never Activate" to your choice of "Always Activate" or "Ask to Activate".

You may also have to install the new WMP plugin (np-mswmp.dll)

• http://www.interoperabilitybridges.com/windows-media-player-firefox-plugin-download

There has been a change in where Firefox searches for plugins and the plugins folder in the Firefox program folder is no longer scanned for plugins, so Firefox won't find them anymore if they are installed in the plugins folder instead of the "browser\plugins" folder that Firefox now scans.

• https://support.mozilla.org/kb/windows-media-or-other-plugins-stopped-working

You can set the plugins.load_appdir_plugins pref to true on the about:config page to make Firefox scan the "<install>/plugins/" directory for plugins like the WMP plugin (np-mswmp.dll).

You can alternatively move plugins from "<install directory>\plugins\" to "<install directory>\browser\plugins\" (create this folder when missing) to make Firefox find them again.
