I was looking at the traffic on my website, and saw some of that from the Amazon silk browser, which shows up as:

Mozilla/5.0 (Linux; Android 5.0; SM-G900R4 Build/LRX21T) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.83 Mobile Safari/537.36

aside from clearly having some sort of identity crisis, the silk browser claims to be a Mozilla product.

The Mozilla license states that source code must be made available.

So I went to the Amazon silk site, and some Amazon sites, but I see no links, or references to download the source. So either Amazon is violating the license by not providing source code, or masquerading as an alternate browser, which (as I understand it) is illegal, under the terms of hacking, and e-crime.

Beyond that, I see no way to contact Amazon about this. What should someone do?

    Not really a licensing issue: Even logs on my server shows things like that. I get Mozilla/5.0 when requesting from Safari on a Mac. And the MPL doesn't force source code to be available: it runs on file-level copyleft, so only changes that you make to the files have to be made available if you distribute it. – Zizouz212 Jan 18 '16 at 22:14

The version field of the HTTP 'user-agent' header is used to communicate compatibility level, not the provenance of the source code. Almost every browser around claims compatibility with Mozilla. In fact Silk is based on the BSD licensed Chromium browser, which doesn't impose a requirement on source distribution.
