Netflix keeps crashing the minute I open it on Firefox due to the Widevine plugin. This has been happening ever since Widevine's latest update about a week ago. I've since learned that their latest update doesn't support MAC OS X 10.9.5, which is what I have. The recommendation on this forum was to install an older version of Widevine. I've looked everywhere and I haven't been able to find out how to do that or where to even find an older version. Widevine's website is not helpful.

Hoping you can help!
