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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1612994 Title: firefox crashes constantly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1612994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
