Details

It seems that the {xre}\browser\searchplugins directory and the files contained within are top main-thread IO offenders in terms of number of Telemetry submissions where they appear in.
Hmm, that's kind of interesting. I would have assumed bug 722332 would have removed the majority of the main-thread hit here.

There are still some consumers who don't use the async API (e.g. bug 785487) but I thought they were a minority. It's possible add-ons are to blame, since we haven't removed the synchronous fallback...
Depends on: 988017, 785487
No longer depends on: 988017
Since bug 1162569, the default engines are in the omni.ja file and we no longer read files in {xre}\browser\searchplugins\*
