Status changed to 'Confirmed' because the bug affects multiple users.

I had this problem with Firefox 48.0.2 and still do with Firefox 49.0; I found the problem traceable to one line of code in 49.0, affecting both the firefox-browser Child process and Adobe Flash Player for Netscape (the source-dcode line refernce d being identical for both debug lines below):

[Child 16807] ###!!! ABORT: Aborting on channel error.: file /build/firefox-h19o_O/firefox-49.0+build4/ipc/glue/MessageChannel.cpp, line 2052
[NPAPI 16865] ###!!! ABORT: Aborting on channel error.: file /build/firefox-h19o_O/firefox-49.0+build4/ipc/glue/MessageChannel.cpp, line 2052

Suspect this to still be the case with 48.0.2.

I saw this in dmesg.

UPDATE: Problems with 48.0.2, 49.0 traced to hardware at my end; no further crashes after replacing the CPU (which replacement postdated the 49.0 release. Considering this Bug still valid for PowerPC platforms.

The problem persists even in the new version Firefox 50.0.2 and after the system update. Same, equal and equal, again and again.

[Wadilson (wadilson)]

I realized that the problem happens when Firefox fetches or delivers something, like in a Twitter window or in a GMail window

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates.
