Can you please post a few more of the crash report id's? Having multiple id's helps to find patterns in the crash reports.

Also, can you try to start firefox in safe mode and see if the problem goes away (hold down the shift key while opening firefox)? This disables a few things that might be the cause of the problem.

Here are the five most recent: bp-d10305e9-1441-4b47-97fd-a9ee92150406 bp-d280621a-cb2c-4d43-916f-6a1892150406 bp-439da9ff-2b38-4aa8-ae32-eb5f02150406 bp-1a8aa56d-9996-4794-a25c-75db32150406 bp-66971b4e-1ade-4b9d-b5d3-db1282150406

I have started it in safe mode a couple of times, and it has still crashed. It has been stable longer, but it did still crash.

I tried creating a new profile; here are the three crashes right after I did that.

bp-fed2134d-8977-4eb3-ba0f-91f332150407 bp-d19a2634-7bcc-4c2e-be3f-ad6202150407 bp-db545c17-2a05-4202-b3dc-349c92150407

I am using Norton 360 (not my choice, my husband put it on to be "nice"). It pops up with gmpopemh264.dll is safe almost every time I open Firefox. I know that's related to a video plugin because I put it in Google but Firefox's main support page doesn't name Norton as one of the ones that Firefox has problems with.

Not really sure why this is happening. This is apparently an issue with the jit compiler but according to http://kb.mozillazine.org/Firefox_crashes that is disabled in safe mode, so this shouldn't be crashing?

I've escalated this question so more people should be looking at this soon. You should receive a response within the next 72 hours.

The one factor that is necessary to eliminate the cause of the crashes is temporarily disabling Norton. If it crashes with it off, then we have ourselves a reproducible bug-> note to self jandern <-

When you disable, also try these steps: https://support.norton.com/sp/en/us/h.../kb20100122090203EN_EndUserProfile_en_us -> note to self follow up with jimb and till-> Rather disable the toolbar

I have confirmed that this is not an JIT issue since it does crash in Safe Mode. We will need to file a new bug with the steps to reproduce.

So Far I have these steps:

1. Create a new profile
2. Launch Firefox from start menu
3. Crashes

With the new crashes, please list them separately with Norton on and Norton off, this will sift between the two signatures seen as well.

Thank you!!!!

Download the current full installer for your Norton programs.

Download and run the Norton Removal Tool to uninstall your Norton product

After rebooting the computer, run the full installers.

I appreciate the replies. The same day I posted this, Norton started throwing up errors too. We uninstalled and reinstalled it, but it seemed like there were several things wrong so we ended up wiping the hard drive again. I haven't tried downloading Firefox again yet since Norton has again given me errors. I appreciate this help. It isn't really solved but I don't want people to feel they need to come in and keep trying to figure it out. I still don't know what has gone on.

HI SpyGlassez, It really is no trouble searching for the root cause, if it ends up being something that we can fix, it will also help others. I very much thank you for reporting this issue. :-)Until next time.
