During GeckoView startup we spend 260ms in AddonManager startup (on a Moto G5). This code is on the critical path during the "App link" startup scenario.

Together with bug 1620447, this makes up the vast majority of time spent in JS code in the parent process during startup. Unlike bug 1620447, AddonManager startup happens before the content process can be initialized, so it delays the initial page load.

Maybe a duplicate of bug 1356825?
From a brief scan of the second profile in comment 0, it looks like a significant chunk of time is importing OS.File (bug 1522925, bug 1408729)
