Browser console errors

[kocjs]

I get a lot of browser console errors, is there anything to worry about?

Unchecked lastError value: Error: Could not establish connection. Receiving end does not exist.
updatePopup moz-extension://0f491beb-69cf-43fc-b5db-a33864e59ed0/background.js:366

view-source:moz-extension://0f491beb-69cf-43fc-b5db-a33864e59ed0/background.js

function updatePopup() {
	chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
		//No active tab!
		if(tabs.length <= 0) return;

		let entry = tabMap[tabs[0].id];

		if(entry != null)
			chrome.runtime.sendMessage({
				action: "updateTabInfo",
				reason: entry.reason,
				target: entry.target,
				status: entry.status
			});
		else
			chrome.runtime.sendMessage({
				action: "updateTabInfo",
				reason: "DynamicHistory is still processing this page",
				status: false
			});

It's fine, it's just the extension trying to update the information in the popup that appears when you click on the extension icon in the toolbar.

I will leave this issue open to remind me to hide those errors.
