User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160725105554

Steps to reproduce:

I have 3 cameras that provide a mjpeg stream each. I created an html page (attached) that just open the stream as IMG. after some time, firefox crash.

I read that it could be a memory leak : about:memory display something like 130MB used and is stable.

I though it could be linked to a plugin : everything is disabled. About extensions, only ReloadEvery is enabled. I disabled it (as I did previously) to confirm it is still failing. AntiVirus as been removed on this machine (McAfee)

Actual results:

Crash reporter is displayed and firefox asks to quit or to restart

Expected results:

We need a full working testcase to reproduce the crash. Is it possible to update your testcase with true cam link?

I am unsure how to do that as those are on a private network. I'll work on it.

Yet I am testing something else : Firefox 51. Until now (23 hours), it didn't failed so I'll update the case asap to confirm if it is solved in newer release.

Yes, it could be already fixed in the next versions like FF50 or 51, especially when it's a crash. Report if the issue is still here.

If that's the case, maybe we can try a solution to build a testcase accessible by Mozilla devs.

OK, I confirm in two days, Firefox 51 with EveryReload doesn't crash anymore. This is an acceptable workaround so I will close the request.

Thank you for your time and patience.
