Bugzilla

[This profile](https://share.firefox.dev/3t9tpPx) was [shared on Reddit](https://www.reddit.com/r/firefox/comments/16teflu/slow_startup_for_firefox/) by a user. It shows a long time (5 seconds) spent waiting on startup, presumably on `WaitForSingleObject(event.get(), 30000);` in `nsWindowsPackageManager::GetCampaignId`, as part of `TelemetryStartup`. This delay of 5 seconds (which could be up to 30 seconds in fact) seems unreasonable for something that blocks startup.

[:bhearsum], is there any way that we could avoid waiting here?

[:bhearsum], is there any way that we could avoid waiting on the main thread here? Would it work to just move the waiting part outside of the MTA closure?
