Package: firefox-esr Version: 52.2.0esr-1~deb8u1 After upgrading my stable Debian install to firefox 52.2.0esr-1~deb8u1, firefox will no longer start up for me. It repeatedly crashes. I can't start it in safe-mode. And even telling it to start with ProfileManager doesn't work. The problem doesn't appear to be profile related. When I start it from the command line, I get the following output before receiving the error popup:
$ firefox (firefox-esr:5793): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed ExceptionHandler::GenerateDump cloned child 5815 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... The popup I receive every time is the firefox error box. It reads: "We're Sorry. Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts. To help us diagnose and fix the problem, you can send us a crash report. . ." If I tell it to restart firefox, I get the same result, every time. Downgrading to firefox 45.9.0esr-1~deb8u1 returns Firefox to a working install. Re-upgrading to the latest version again produces the problem.
