Chrome doesn't allow crx2 format anymore

[raul1991]

Is there a way to download the crx3 version of the the plugin?

Problem

I am using addExtensions method of the latest webdriver which now asks for loading it via a file instead. So I dumped the base64 after decoding it into a file and gave it to it and that's when I got the following error

[session not created: cannot process extension #1 from unknown error: CRX verification failed to parse extension header. Chrome supports only CRX3 format. Does the extension need to be updated?]

I ensured, before raising a ticket here, that it still works with the older version of the webdriver.
