Status: RESOLVED FIXED

(Toolkit :: Telemetry, defect)

Attachment: Do a strict inequality comparison

We're not reporting any of the gfx system info fields whose value is boolean "false" because of a bad comparison in TelemetryPing.js

> false != ""
false

> false !== ""
true

Could you take the opportunity to make this
 let value = gfxInfo(field);
?

You'll need a comment to explain why you need a strict comparison here (i.e. it's not evident that we're comparing booleans with strings in some cases or that |"" == false|).
