Hello! I would like to take this on as my first bug. I've got a local build setup, I've read the contribution guidelines, and I've gone through the reviewer checklist. I'm going to start by trying to repro locally and then poke around to try and figure out where I should be.

I would love any suggestions as to where I should be looking! I'll try to find my way based on the related bug ticket.

Hi Zachary,
Thank you for your help!
First, you can follow the description to see if you can reproduce it.
And then you can search this keyword, "test-unwanted-simple", in Firefox codebase.
We probably forget to remove the test table somewhere.

Thank you, your help was invaluable!
I believe I was able to create a fix that accurately addresses the issue and I've submitted it for review.

I amended my original change, I think I'm ready for review again!

Hi Zachary,
Comment 10 says that the patch didn't pass our automation tests.
This is because some of our tests are still checking whether "test-unwanted-simple" exists.
You can find the related code here.
Please let me know if you want to continue to work on this, thanks!

There's a r+ patch which didn't land and no activity in this bug for 2 weeks.
:cczac1, could you have a look please?
For more information, please visit auto_nag documentation.

Dimi, this is a P2 with a 2 months old WIP patch, could you find an owner for it or lower the priority if we can't fix it in a release in flight? Thanks

I have managed to reproduce the issue on latest Nightly 73.0a1 (2019-12-03), so I will update the flag accordingly.

We could still take a patch for 73 and potentially for 72, Dimi, is this something you might still work on?
