Hi Scott, Regarding the CDMs (Widevine, OpenH264), I asked similar questions here before and after ESR 52, but didn't get a lot of feedback. From what I understand, it's a licensing issue, and neither Mozilla or organizations like us can legally re-distribute these CDMs.
For our organization the best solution for Widevine was to set media.eme.enabled to false. This doesn't actually disable Widevine, instead it disables the silent download and installation of it on first run, and prompts for it only when the user goes to a page that requires Widevine. OpenH264 isn't controlled by that preference and doesn't seem to have an equivalent. This CDM is only for WebRTC (a specific kind of video conferencing) and doesn't seem widely implemented. Because it's very small, we currently left this one as is, but I'm considering disabling completely. I really wish Mozilla had given some consideration with the CDMs for organizations like us who have highly managed and shared computers. ------------------------------------------ Jason Jackson Computer Systems Technician North Vancouver School District From: Enterprise [mailto:[email protected]] On Behalf Of Copus, Scott Sent: May 12, 2017 9:25 AM To: [email protected] Subject: [Mozilla Enterprise] automating first-run tasks (changing application handlers, preinstalled plugins) Hi, I'm using the CCK2 to automate a bunch of the first-run tasks. Current using latest ESR 52.1.1 x32 on Windows 7x64. I need to be able to set a bunch of options on first-run that get set up before there is any existing Firefox profile. First, I'm trying to automate setting Adobe Acrobat Reader as the default PDF handler and get it to open "externally". I've tried using Mike Kaply's code suggestion at: https://mike.kaply.com/2013/05/15/setting-default-application-handlers/ But it only picks up the settings after I close and restart Firefox. Is this a first-run timing issue? Any known workarounds? Second, is there a way to pre-install (to a fresh new profile) the default video codecs (Widevine/OpenH264/etc) so they're available IMMEDIATELY at launch and not wait for Firefox to download them? Is there a way to search this list's archives? Thanks. -- Scott Copus, Lab Systems Engineer Academic Technology | Western Kentucky University http://www.wku.edu/it/labs
