1702637 - BrowserTestUtils.switchTab should not wait for an implied timer from AsyncTabSwitcher

Status: NEW

(Firefox :: General, enhancement)

Description

[Florian Quèze [:florian]]

BrowserTestUtils.switchTab waits for the TabSwitchDone event from AsyncTabSwitcher, but that event happens after a 300ms timer.

On debug builds that doesn't change the timing much, but on optimized builds, that makes the tests run significantly slower than they need to.

I'm going to attach a WIP patch, but if we want to go ahead with it I'll have lots of tests to debug, as my try run is currently pretty orange: https://treeherder.mozilla.org/jobs?repo=try&revision=d44cba986ec22d6e32218c2fd5573bda5151bad0

The bug assignee is inactive on Bugzilla, so the assignee is being reset.

Sorry, there was a problem with the detection of inactive users. I'm reverting the change.

Resetting the assignee as I'm not actively working on this. But I still think this is worth fixing!
