Description

[Kostas]

STR:(in win 10 64x)
- having installed Nightly 45.0a1 x64 2015-11-22 and running
- launch: 
"C:\Program Files\Nightly\firefox.exe" -no-remote -profilemanager
and create a new profile. Then launch it.
Notice in %appdata%\Mozilla\Firefox\Profiles\new_profile_name\
that after a while of using Firefox, a new directory 'gmp-eme-adobe' is created (containing 3 files in it's subdirectory '16' : eme-adobe.dll, eme-adobe.info and eme-adobe.voucher).
- Now close Firefox. Relaunch profile Manager via
C:\Program Files\Nightly\firefox.exe" -no-remote -profilemanager
and delete that profile. 
You' ll notice that the 'gmp-eme-adobe' directory and its contents are still there.

We don't do anything special when deleting the profile...

We're just calling nsIFile's Remove() method, which should recursively remove the files.

I wonder if something not closing the files properly, and Windows thinks they're still in use? If you reboot after gmp-eme-adobe is created, but before deleting the profile, does it work? (If so, that would tend to imply it's something happening during the initial install of the files.)

I just rebooted after gmp-eme-adobe was created (without deleting the profile).
Then, I started Profile Manager and deleted the profile (without having launched Firefox first).
But, the 3 files remained.

[Randell Jesup [:jesup] (needinfo me)]

Likely deletion fails if the files are open; perhaps there was a lingering process with them open?

Someone else should verify

Not critical in any case though

So Chris has recently pulled all the Primetime stuff out of Firefox and I can't reproduce this with Widevine, so I'm going to close the bug
