Everyone of those Crash Reports red flagged this file chtbrkg.dll along with a file that is part of MalwareBytes Anti-Exploit - mbae.dll.

chtbrkg.dll has been a TopCrasher for awhile now. https://bugzilla.mozilla.org/show_bug.cgi?id=1290403

And a search via Google shows that chtbrkg.dll is known as Malware.
