Question

Google Play Music crashes Flashplayer 24.0.0.x (Firefox/Linux 64-bit)

Running Fedora Linux 25 (64 bit) with included Firefox 50.0.2, and Flashplayer plug-in installed via Packet Manager from Adobe. A couple of days ago, the official Linux release was upgraded from 11.2.202.644 to 24.0.0.186. With release 11.x, Flashplayer plug-in was rock-solid for years. Worked just great.

However, Flashplayer 24.0.0.186 (also tried 24.0.0.189 beta) always crashes on Google Play Music while loading the web page. Google doesn't seem to offer any HTML5 alternative for Firefox users (like on YouTube when ffmpeg library is detected by Firefox), so the service is unusable now. Easy to reproduce. Crashes always. Only downgrading to Flashplayer 11.2.202.644 helps.

Already tried to clear local settings (~/.adobe, ~/.macromedia), cookies and stuff, but that won't change anything. Happens also on different hardware and with a fresh Firefox profile. Looks like a general problem on Linux.

During the crashes, Firefox outputs messages like these on console:

###!!! [Parent][MessageChannel::Call] Error: Channel error: cannot send/recv

###!!! [Parent][MessageChannel::Call] Error: (msgtype=0xB80006,name=PPluginInstance::Msg_NPP_SetWindow) Channel error: cannot send/recv

Any help is appreciated. If there's a better place to report problems like this (kind of bugzilla), please let me know.

    Thanks for the feedback.  If you could provide a link to a crash report, that would be really helpful.

    In Firefox, go to about:crashes

    Click one of the links that corresponds to this crash (they're time-stamped) to submit it to Mozilla for analysis.

    Copy the address of the page that opens and paste it here.

    Merry Christmas!

    Fedora people created a new build of their version of Firefox with the crash reporter enabled. Now I was able to successfully catch the issue when it happened and then upload a report to Mozilla servers. It's available here:

    [@ libflashplayer.so@0x673e9f] - Firefox 50.1.0 Crash Report - Report ID: 7ddcde92-ec2d-4120-a075-bbdd52161225

    Maybe that helps to track down the issue a little better and find out what component of Fedora's build of Firefox triggers the problem.

    I've created a fresh Linux account for that (no previous configuration, cache, cookies or whatsoever). Everything is on its default settings.

    Good news is, so far I've had no other issues with Flashplayer 24.0.0.186 for Linux. Plays sound, shows video, works fine. Very solid! Google Play Music seems to be the only site that doesn't work (and as said before, it works also fine with the old Flashplayer 11.2.x series). Maybe that information helps.

    By the way, the related Fedora bug ticket can be found here:

    https://bugzilla.redhat.com/show_bug.cgi?id=1405287

    There's also a (very short) discussion on Google Groups with one other person having the same problem (but no new technical facts):

    Google Groups

    Thanks a lot for your support! Wish you a Merry Christmas and a Happy New Year!

    The crash report in comment 5 is distinct from the issue being discussed here. 


    All of the reports of the crash reported in this thread (there are only 14, which is very low) come from a total of 3 unique machines.  It's interesting, but pretty low in terms of priority.  I'll continue to keep an eye on it, but I'd recommend trying the stock Firefox distribution.  When I see crashes that come from only a couple machines, they tend to be related to environmental quirks (unexpected compiler options, third party software conflicts like oddball antivirus or anti-tracking products, etc.).
