User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.2 Safari/605.1.15
Steps to reproduce:
This has existed for many many years on multiple machines that I have owned and I'm only just now reporting it. I don't know the precise issue (too much cpu use, too many context switches? )
If I use Firefox on MacOS (many versions from 10.12 - 11.5.2) if there is an update available which I haven't downloaded or installed, then the computer goes absolutely crazy.
Actual results:
If I use Firefox on MacOS (many versions from 10.12 - 11.5.2) if there is an update available which I haven't downloaded or installed, then the computer goes absolutely crazy.
The CPU load increases. The temperature (as displayed by smcFanControl) climbs to 82dC or more. The fans go full blast.
If I update firefox or close it, then the computer calms down again.
Expected results:
Having an update available should not make the computer does not go crazy.
Workaround: close firefox or update it.

The Bugbug bot thinks this bug should belong to the 'Toolkit::Application Update' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I'm not really sure how to troubleshoot this. I'm going to try sending it over to our Performance team to see if they have any thoughts.

Oh! You might want to use the Firefox profiler. If you send us a profile of when this issue is happening, we might be able to identify what is causing it.
Do you think you could do that? Let us know if you need some help.

I am trying to reproduce it with nightly but haven't seen it yet.
I have previously seen it in developer edition. But I will absolutely run Firefox profiler if I catch it again.

I have a profile now. Shall I pass the link here or is there a more secure method?

If you are comfortable pasting it here, that is fine. Otherwise, you could send it directly. You can send it to me on chat.mozilla.org. I'm bytesized there.
I believe that it is possible for profiles to contain sensitive information such as what websites you had open while profiling.

Hi Ewan and Kirk -
Is a profile available for us to help diagnose the problem?
When you share a performance profile you have the option to not share URLs or screenshots (this is the default).

Closing this one as we haven't heard back from the reporter for one month.
Please feel free to attach a profile and report if it still occurs.
