I was trying to write a simple extension in Firefox wherein I modify the X-Frame-Allow header.
I looked at the documentation briefly and I see that they support webRequest.onHeadersReceived.addListener(). However, I'm unable to get my code to run when the headers are received.
manifest.json
{
"manifest_version": 2,
"name": "xframeoptions",
"version": "1.0",
"description": "Set X-Frame-Options to ALLOW",
"icons": {
"48": "icons/icon.png"
},
"permissions": [
"webRequest",
"webRequestBlocking",
"<all_urls>"
],
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["xframeoptions.js"]
}
]
}
xframeoptions.js
function rewriteHeader(e) {
console.log(e.responseHeaders);
for (var header of e.responseHeaders) {
console.log(header.name + ":" + header.value);
if (header.name == "X-Frame-Options") {
header.value = 'ALLOW';
modified = true;
break;
}
}
return {responseHeaders: e.responseHeaders};
}
console.log("Initializing xframeoptions extension ...test");
browser.webRequest.onHeadersReceived.addListener(
rewriteHeader,
{urls: ['<all_urls>']},
["blocking", "responseHeaders"]
);
How do I modify response headers via Firefox's WebExtensions?
Content scripts do not have access the API you are using
You are attempting to do this from a content script. You need to be doing this from a background script. Content scripts have access to a small subset of the WebExtensions APIs. The available APIs include (from the MDN Content Scripts page):
From extension:
getURL()
inIncognitoContext
From runtime:
connect()
getManifest()
getURL()
onConnect
onMessage
sendMessage()
From i18n:
getMessage()
getAcceptLanguages()
getUILanguage()
detectLanguage()
Everything from storage.
This does not include the API you are trying to use (e.g. webRequest).
Change your manifest.json to use a background page
You should change your manifest.json to instead of having a content_scripts key for your xframeoptions.js, run it as a background script using something like:
"background": {
"scripts": [
"xframeoptions.js"
]
},
Extensions are separated into background scripts and content scripts
If you need the information from calling the API in your content script, you will need to use message passing to communicate between the content script and your background script. However, often you can move the complete logic to a script running in the background context (background scripts, popup scripts, options page scripts, etc.). What, exactly, will be required will depend on what you desire to accomplish with your script.
This separation of functionality between all privileged APIs being available in the background context and access to web page content available in content scripts (with very limited access to privileged APIs), with asynchronous messaging between them, is fundamental to how extensions are architected. You will need to design your extension around this architecture.

This question led me here. I had a problem with a browserAction. This line was in my background.js for handling a click on my extensions' icon:
browser.browserAction.onClicked.addListener(handleClick);
That line gave me this error:
TypeError: browser.browserAction is undefined
What was the problem? I just forgot to define a browser_action in my manifest.json:
"browser_action": {
"default_icon": "my-icon.png"
}
Maybe this hint could be helpful for someone else… ;-)
