hi menders34, thanks for providing a crash report id. we have seen quite a number of similar reports about this issue in the last hours and this issue is likely caused by your symantec security software that is hooking into firefox (probably through a program/signature update done by them). other users reported that updating firefox in this situation helped with the crashes. you can download & install the latest firefox from https://www.mozilla.org/en-US/firefox/all/

Thank you for your reply Philipp! Unfortunately, we cannot update the users to the latest version of Firefox because they use version 41 for a specific website. What else can we do to get these users resolved & working ASAP?

Thanks

and the users who need version 41 are NOT all affected. So all the users have Symantec Endpoint & all them have version 41, but 2 are having the error.

PLEASE HELP!

in this case you should get in contact with symantec's support to inquire if they have a fix available and in which form they are planning to release it.

other affected users also reported that rolling back the last client intrusion prevention signatures can help: http://www.symantec.com/connect/forums/firefox-problem-after-sep-update

SEP did not push any updates & neither did our System Admin. IF there was an update pushed out by SEP, then all the users using version 41, would be affected. I was able to install version 41.09b for the 2 users who are having this issue, but I need to get a resolution, so I can reinstall version 41 on the 2 user machines.

On 9/13/16 @ 9:27AM, I posted that SEP did not push out any updates & neither did our System Admin for Symantec Endpoint Protection. I was able to install version 41.09b for the 2 users who are having the issue, but I need to get resolution so I can reinstall version 41 on the 2 user machines.

Please help!

Thanks Melissa

please see https://support.symantec.com/en_US/article.TECH235780.html

looks like we have SEP Version 12.1.6 (12.1RU6 MP5) build 7004 (12.1.7004.6500)

Is this the issue?

no, the ips signature definitions on those affected systems are the issue
