Yet, the plugins tab will show Widevine as now installed.
Can reproduce on Firefox 53 on mac :(

the CDM doesn't install automatically, making it impossible to watch netflix without navigating in the preferences.
The log shows that the "last check was less then a day ago". Can you make sure that media.gmp-manager.lastCheck pref is reset in about:config before you restart? It seems like there was either a recent check that didn't find a widevine cdm to download, or something is off with our lastCheck pref.
Flags: needinfo?(jyavenard)
That's because I restart FF often with the STR above. 
the check fails...

After a few restart, the CDM is still not downloaded. When you manually force to check for an update, only then will it download it.
Flags: needinfo?(jyavenard)
I'm unable to reproduce this. Widevine is downloaded within a minute after first start. Can you please post a new log that shows the URL that's used by the automatic check? You mention that "the check fails". What exactly is the failure that you see? You will need to make sure that the lastCheck pref is reset to get a log with this URL.

Here is my log for reference:

I'm assuming the check fails because the CDM shows up as ""Widevine Content Decryption Module provided by Google Inc will be installed shortly" forever ...

I will retry... but I can consistently reproduce it on Nightly (both mac and linux) and release 53 on mac
on two different physical location and 3 different machines.
Flags: needinfo?(jyavenard)
This video https://www.youtube.com/watch?v=HxYIoWO4DoA&feature=youtu.be shows another user struggling to get the CDM to install.

This one is with ESR52...

It's definitely not just me :(
Flags: needinfo?(cpearce)
I also cannot reproduce this. Based on your log jya, it seems the XHR to Google's download server is failing.

¡Hola!

So it turned out that one of the hacks I use to bypass geo blocks was somehow making the connection to https://redirector.gvt1.com/edgedl/widevine-cdm/1.4.8.1008-win-x64.zip insecure.

Undoing the hack allowed the CDM to download correctly.

Mad props to glob and cpeterson for putting up with ranty me on #firefox while helping me to figure out the root of the issue.

Further variants of my particular issue in case I bump into these in the future:

[Tracking Requested - why for this release]:

¡Hola!

Seems to still be an issue on 67 https://support.mozilla.org/questions/1261833 and 69 https://support.mozilla.org/questions/1268553

Perhaps worth tracking?

¡Gracias!
Alex

Andrei can you help find someone to try to reproduce this? (on 69 but maybe more usefully, on 71 nightly) Thanks!
I'm not tracking unless we know that this is a widespread issue but let's see if we can uncover a problem here.

I was able to reproduce this. Turns out, the adblocker module in my router blocked requests to gvt1.com (it's part of https://easylist-downloads.adblockplus.org/easylist.txt)
