When i try to use insertCSS api of WebExtensions
i found that only offical addons site (https://addons.mozilla.org) cannot trigger the insertCSS api
https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/tabs/insertCSS
here my example code:

browser.runtime.onMessage.addListener((req, sender, res) => {
	if (req.message === 'active') {
           browser.tabs.insertCSS(tt, {file: './css/test.css?v='+id, runAt: 'document_start'}) 
	}
})
