771077 - Create new talos test: measure firstPaint time with lightweight themes

Status: RESOLVED WONTFIX

(Testing :: Talos, defect)

Description

[Tim Taubert [:ttaubert] (inactive)]

We need talos tests that measure firstPaint times when starting up with lightweight themes applied. We're currently fixing a lightweight theme related slowdown in bug 650968 but we don't have any measurements to tell us about the kind of impact the fixes will have. Also, without a talos test chances are high that we accidentally regress these efforts in the future.

We can do track this via telemetry too(we've been submitting the selected persona for a while now). Having a talos test will ensure that we do not regress this in the future.

Ah, I forgot about that. Cool, so we have some measurements already, good.

Mark, can you see if someone on your team can implement this? This should be very similar to ts_paint. This is important for improving a widely used persona themes feature.

closing out old bugs that haven't been a priority
