1907408 - Slow load of Firefox View

Status: NEW

(Firefox :: Firefox View, defect, P3)

Description

[Asif Youssuff]

I noticed when opening Firefox View that it opened slowly.

Steps to reproduce:

1. Use Firefox and have a lot of open tabs
2. Click Firefox View icon

What happens:

The feature opens slowly and doesn't feel "native". There is a perceptible delay after clicking and before anything seems to happen on the screen.

Expected Result:

Given that this is supposed to be a native feature and not a web page on the other side of the world, this should feel fast - if not instant.

Thanks for the profile. About half the jank there seems to be in producing the sorted recent tabs list, which requires a call to get the lastSeenActive property. We did just land a patch in bug 1882655 which should improve this.

Is this still reproducible since landing bug 1882655 ?
