I have a firefox webextension ported from chrome extension. The executeScript call fails on this site.
https://addons.mozilla.org/en-US/firefox/
I tested with multiple pages on this site and all are giving the same error
The bare-minimum code to reproduce this is
popup.js
document.addEventListener("DOMContentLoaded", function () {
chrome.tabs.query({"active": true}, function(tabs) {
chrome.tabs.executeScript(tabs[0].id, {"code": "console.log('Script executed in ' + document.location.href);"}, function(r) {
if(chrome.runtime.lastError) {
console.log(chrome.runtime.lastError);
document.body.innerHTML = 'Execute script Fail. check console';
} else {
document.body.innerHTML = 'Execute script Success';
}
});
});
});
manifest.json
{
"manifest_version": 2,
"name": "execscript_test",
"short_name": "execscript_test",
"version": "0.0.1",
"description": "desc",
"icons": {
"19": "images/icon19.png",
"38": "images/icon38.png",
"128": "images/icon.png"
},
"applications": {
"gecko": {
"id": "[email protected]",
"strict_min_version": "48.0"
}
},
"background": {
"scripts": ["background.js"]
},
"permissions": [
"tabs",
"<all_urls>"
],
"browser_action": {
"browser_style": false,
"default_icon": "images/icon.png",
"default_title": "execscript_test",
"default_popup": "popup.html"
}
}
background.js - file is present but it is empty
popup.html
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<script src="popup.js"></script>
</head>
<body>
</body>
</html>
On https://addons.mozilla.org/en-US/firefox/addon/engrip-tracker/?src=search page I clicked on the browser button and got this error in browser console
Error: No window matching {"matchesHost":["<all_urls>"]}

I thought it could be some url scheme issue but this happens even on https://addons.mozilla.org/en-US/firefox/
The same code works without error on chrome.
I am on FF v50. I tested this on FF nightly also (v53.0a1) and the error persists.
Is this something specific to this site? Or am I missing something here?
actionButtonwithout using a popup. The problem still exists in that case (i.e. it is not a problem related to the fact that this is being done in a popup.) – Fortechrome.tabs.querywill need at least one additionalqueryInfoproperty. Without something restricting this to a single window, you will get multiple entries in yourtabsarray, if you have more than one window open. This will normally becurrentWindow: true, but could be different, or more complex, depending on what you desire. One way or another, you are assuming that the tab you desire is the first one in the array of results. Currently that is not guaranteed based on the parameters you have provided. – Fortehttps://chrome.google.com/webstore. – Forte
