Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

  1. Right click -> Inspect Element -> Go to Network tab
  2. Refresh current page, or leave it on and browse a bit
  3. A kernel panic happens

I'm on macOS Big Sur 11.0.1 (20B29) + Firefox 83.0 (64-bit), running on a 16" MBP with a Radeon Pro 5500M. This happens when using either the dedicated GPU (MBP in calmshell mode connected to dock+external monitors) and integrated GPU (laptop only, on battery).

I can semi-consistently reproduce this; it seems to happen when there's a high volume of requests happening at a fast rate.

Actual results:

A kernel panic:

Expected results:

It should not cause a kernel panic.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Component: Untriaged → General
Product: Firefox → DevTools

Thanks for the report!

Two questions to help the investigation:

  • is there a public URL we could use to reproduce this bug (to get a better idea of how many requests we are talking about)?
  • is there any info in about:crashes when this happens?
Component: General → Netmonitor
Flags: needinfo?(bugzilla)

Hello Ray C,
Gentle reminder,
Please see Julian's questions above which would help figure out what is going on
Thanks so much

Apologies for the late follow-up!

I have a new crash log that may help. It seems to be coming from plugin-container this time, and happened the moment I hit F12 to open the Inspector.

is there a public URL we could use to reproduce this bug (to get a better idea of how many requests we are talking about)?

It's hard for me to pinpoint exactly due to my mixed usage. This has also happened when I tried opening a new Incognito window through Cmd + Shift + P, so it doesn't seem isolated to just the Inspector.

I've noticed it happening more frequently when I have several Twitch.tv streams open in different tabs, maybe that could help?

is there any info in about:crashes when this happens?

Not that I can tell. I only have two crash reports listed in about:crashes which predates this issue (both dated May 2020).

Flags: needinfo?(bugzilla)

Thanks for the feedback, this doesn't sound like a devtools issue if it occurred without DevTools opened.
I found a similar bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1679400

They reported that the issue was fixed after updating to BigSur 11.1
From the crash report, it seems you are on Macos 20B29, which is 11.0.1.

Could you try to update to 11.1, and see if this fixes your issue? If it doesn't, do you mind reopening Bug 1679400 .
