web-platform-tests have been running against GeckoView for a couple of months, and we've found that the following tests have been unstable. I'm bulk disabling the most unstable tests based on this try push and filing this bug to track the work needed to turn them back on.

Andrew, I know there's a refactoring coming up in service-workers that will change these results. Nevertheless, could you assign someone to turn these disabled tests back on and green them up? Thanks!

Hsin-Yi is actually the manager of the team so I'll defer to her.

Thanks for bringing this up. I'll take an action and see how we can have a plan.

P3 for now.

The leave-open keyword is there and there is no activity for 6 months.
:jstutte, maybe it's time to close this bug?

:perry, can we close this?

I suspect that some tests could be reenabled but not all, in which case this would need to remain open. I'll run some tests to see what might be able to be reenabled...

Remaining GeckoView SW WPTs to be re-enabled, according to comment 3 and patch D59944:

We still need to re-enable those tests.

Hi Randell, could you give them a try?

I'll look at them

For more information, please visit auto_nag documentation.

Joshua, could you please verify which tests are still disabled and try to understand if there are low hanging fruits?
