Bugzilla

[androidx.compose.material.pullrefresh](https://developer.android.com/reference/kotlin/androidx/compose/material/pullrefresh/package-summary) which would use distance data instead of  `MotionEvent`s is an API available for [Compose](https://developer.android.com/jetpack/compose). The app has basic support for this, which I based my RFC on while in production it is using the old xml based layouts and the older [SwipeRefreshLayout](https://developer.android.com/jetpack/androidx/releases/swiperefreshlayout).
With the long term goal for the app being to be migrated to Compose I suggest migrating to compose and [androidx.compose.material.pullrefresh](https://developer.android.com/reference/kotlin/androidx/compose/material/pullrefresh/package-summary) at the same time with migrating to a new distances based API from GeckoView.
If that effort is deemed to take a longer time then we can also implement our own throbber and animate it "manually" based on cached data (distances) from `MotionEvent`s but with not actually sending the `MotionEvent`s to the [SwipeRefreshLayout](https://developer.android.com/jetpack/androidx/releases/swiperefreshlayout) like you suggested. While this doesn't seem to be supprted now in official libraries there may be some 3rd party ones available or we could implement our own.
