Status: RESOLVED WORKSFORME

(WebExtensions :: Untriaged, enhancement, P2)

Description

[ihor.ibm]

What did you do?
================
1. Used setTimeout inside an app
2. Tested it (about:debugging) as a web extension

What happened?
==============
Events that should have took tens of milliseconds to happen took seconds

What should have happened?
==========================
Obvoiusly, it should have worked same as it works everywhere else

Is there anything else we should know?
======================================

Both with setTimeout and setInterval. It starts out normally for me, but then degrades after around two seconds and gets progressively worse and worse second after second.

		let		interval_time	=	Date.now()

		setInterval(
					()=>{
						if	(
								Date.now()	-	interval_time
							>	100
							)
								{
								interval_time	=	Date.now()
								console.log	(	'good'	,	interval_time	)
								}
							else
								{
								console.log	(	interval_time	)
								return;
								}
						}
					,
						5
					)

Or, better

let		interval_time	=	Date.now()

setInterval(
			()=>{
				if	(
						Date.now()	-	interval_time
					>	100
					)
						{
						console.log	(	'good'	,	Date.now()	-	interval_time	)
						interval_time	=	Date.now()
						}
					else
						{
						console.log	(	Date.now()	-	interval_time	)
						return;
						}
				}
			,
				5
			)

I'm not talking about background pages here, but about open active extension windows (browser_action ➙ popup)
