Package: firefox-esr Version: 60.5.0esr-1~deb9u1 Last night I upgraded and now it shows me a yellow banner saying "Firefox is installing components needed to play the audio or video on this page. Please wait." I waited about 20min, reloaded the page, still wouldn't work. I removed firefox-esr and manually downloaded and installed the last update
http://security-cdn.debian.org/debian-security/pool/updates/main/f/firefox-esr/firefox-esr_60.4.0esr-1~deb9u1_amd64.deb Netflix is working again. This is a Stretch amd64 system. I didn't bother debugging any further as I don't know much about debugging FF. Netflix is HTML5 uses widevine as far as I know for DRM. I use multiarch for Crossover 17 to support Xfinity's Streaming TV which still uses Adobe Flash and only works properly with a windows firefox, and have backports for hedgewars and libphysfs3 it requires. Other than that my system is pure Debian 9.7 Stretch and up to date.. so I imagine the issue should be reproducible. I'm not sure what exactly has broken or why it would even attempt to download components I obviously already had in FF previous release. If there is anything else I can do to help run down the issue, let me know. For now I'll be staying on this 60.4.0esr-1~deb9u1 until the next update and I'll be keeping this package around in case its still not fixed as this is all I use FF for.
