I need to install Google Widevine on my Windows 7, Firefox browser, but it does not work.
I tried various sources but I always get this answer: The add-on downloaded from this site could not be installed because it appears to be corrupt.
I use Norton security.
I am at lost what to do.

A few users have reported issues with downloading addons from external sources. Please try the following:
- Go to the Widevine download page
- Right click the download link for Firefox on Windows
- Select Save link as... to save the XPI file to your hard drive
- Go to the Firefox addon manager or
about:addons - Click the gear icon
- Select Install addon from file...
- Open the XPI file when prompted
This should install the addon and it should be functional. If not, let us know.
Note: Once the addon has installed successfully, you may delete the XPI file that you downloaded.
Thank you but although I followed your steps I get exactly the same response.
It could be because this addon is not signed. Signing in an automated process that checks for potential threats. To protect our users' security, all unsigned addons have been blocked from running in Firefox.
To allow unsigned addons, please try the following:
- Go to
about:config - Locate the
xpinstall.signatures.requiredboolean - Change the value to
false - Try installing the addon, via the website
- If that doesn't work, try install the addon by using the steps in my previous post
