I'm making an extension which replaces the users new tab page, and i would also like it to replace the users start up homepage. Right now in my manifest I'm using:
"chrome_settings_overrides" : {
"homepage": "givr/index.html"
},
But when i try to install the extension I get the error stating it's not a valid value:
"ErrorInvalid value for overriding homepage url: '[givr/index.html]'."
Any ideas?
Try something like this, it worked for me:
"chrome_settings_overrides" : {
"homepage": "https://own.intra.site/index.html"
}

I'm creating a webapp in electron, a web-crawler with a neural network, which needs all webSecurities to be disabled
i tried modifying the headers (X-Frame-Origin,access-control-allow-origin
etc..) , using flags like chrome --allow-file-access-from-files --disable-web-security --user-data-dir="" etc... nothing seems to remove the error above
The iframe is showing the ORIGIN restricted websites after i modified the xframe header, but when i try to access its document, the error above pops
i tried running it in chrome and firefox, and the same behaviour is encoutered
been googling for 4 hours now and i can't seem to find an appropriate answer. if you think this is a duplicated please include a link, it would help a lot
i found the solution ,the disable site isolation trial should be toggled on :
app.commandLine.appendSwitch('disable-site-isolation-trials')
The only solution I've found that is not deprecated (so far, to this date) is the bellow, old aproaches like webPreferences: { webSecurity: false } wont work anymore as webSecurity no longer controls CORS.
mainWindow.webContents.session.webRequest.onHeadersReceived({ urls: [ "*://*/*" ] },
(d, c)=>{
if(d.responseHeaders['X-Frame-Options']){
delete d.responseHeaders['X-Frame-Options'];
} else if(d.responseHeaders['x-frame-options']) {
delete d.responseHeaders['x-frame-options'];
}
c({cancel: false, responseHeaders: d.responseHeaders});
}
);
I am using Angular-translate (PascalPrecht module) with StaticFilesLoader in mean.js. But getting the error in browser console as ,
http://localhost:1234/app/languages/es.json 404 (Not Found)
and the translation is not working.
I tried all the options in other sites but my issue still persists. Can anybody suggest how to set path to json file in mean.js
This is my code
public/module/user/config.js
$translateProvider.useStaticFilesLoader({
prefix: 'app/languages/',
suffix: '.json'
});
$translateProvider.preferredLanguage('es');
and i set my json file in app/languages/es.json
{ "TITLE": "Hello", "SUBJECT": "this is it" }
This is difficult to know for sure without seeing your whole app structure. Where is your directory "app" located? If you try to open http://localhost:1234/app/languages/es.json in your browser address bar, does it work? What is the URL for config.js? If it's: http://localhost:1234/module/user/config.js then I believe you just need to move the app/languages tree under 'public'.
This is my first time messing around with extensions and what I am trying to do is very simple yet I can't seem to get it to work.
I simply want an alert to be called every time a page on google is loaded.
In my manifest.json I have:
{
"name": "Bypass shib",
"version": "1.0",
"content_scripts": [
{
"matches": ["http://www.google.com/*"],
"js": ["secondScript.js"]
}
],
"manifest_version": 2
}
Okay now in my secondScript.js I have:
chrome.tabs.executeScript(null, {code: "alert('test')"});
Shouldn't this execute the alert whenever a page is loaded? If not can somebody explain why it's not?
The console reveals the following message:
Uncaught Error: "executeScript" can only be used in extension processes.
See the content scripts documentation for more details.
This post suggests "Chrome extension functions cannot be used in content scripts," which could be what you're running into.
For completeness, the secondScript.js that worked for me was as follows:
console.log("test");
//chrome.tabs.executeScript(null, {code: "alert('test')"});
alert("test");
Content scripts do not have access to any of the chrome.tabs.* API methods.
To display an alert on every page, remove the chrome.tabs.executeScript method, and let your secondScript.js just contain:
alert('Test');
In a Chrome extension, there are three different kinds of scopes in which JavaScript can run. The understanding of this separation is essential for writing Chrome extensions, see this answer.
The integration guidlines for the Spotify Apps API mentions DefaultTabs and how it should be expressed in the manifest.json file to achieve tabbing in your Spotify app. Unfortunately I have problem getting this to work and the app that it refers to (Tabs, with the URI spotify:app:tabs) for example doesn't exist in my preview build of the Spotify application.
The application can specify what tabs it wants in the manifest file, in the DefaultTabs attribute. The attribute must be a list of records. Each record must contain the attributes arguments and title. The title can, and should, be localized by making it into a record with attributes for each language (currently en, fr and es).
I have tried the following:
Adding this snippet to my manifest.json file:
"DefaultTabs": [{
arguments: [],
title: {"en": "På TV4"}
}
]
Quitting the Spotify application and reloading it.
Load my app by entering it's address spotify:app:name in the address field.
Here I expected to see the tabs loaded, but it wasn't. Any help with the correct syntax would be appreciated.
I had a few issues at first too, but the following snippet works for me:
"DefaultTabs": [
{
"arguments": "test",
"title": { "en": "test" }
},
{
"arguments": "test2",
"title": { "en": "test2" }
}
]
I think you are probably missing the arguments.

I'd like to make a very simple extensions that slightly alters how the Downloads page looks. Changing the History page might be interesting too, but that's for later.
Is there a way to do that?
I tried making a Content Script extension, with "chrome://downloads" as match in manifest.json. Chrome won't allow that and responds with an error when packaging the extension.
Is there another simple way? It has to be simple, because changes would be simple, because all chrome:// pages are built with HTML, JS and CSS.
edit
After trying with background scripts a little...
I can't get chrome.tabs.executeScript to work! I added in background.html:
chrome.browserAction.onClicked.addListener(function(tab) {
alert(this.document.body.innerHTML);
alert(chrome.tabs.executeScript(null, {
code : "document.body.style.backgroundColor = 'red';"
}));
});
And I added this in manifest.json to add a (invisible) 'browser action button':
,"browser_action": {
/* "popup": "background.html",*/
"name": "Alter page"
}
The onClicked event fires both alerts (first is background.html's body, second is undefined). But the code (a string with document.body.style.backgroundColor = 'red';) doesn't execute! And ofcourse there's no debugging for extensions like this =)
Any tips anyone? I'm trying to get a hold of the tab's window.document (not background.html's window.document!). An injected script (that's what chrome.tabs.executeScript is supposed to do) should do that.
PS
I'm stealing from make_page_red/manifest and make_page_red/background.html
The 'extension' I have so far: http://hotblocks.nl/js/downloads.rar
EDIT
I found out what I want to achieve is possible with just CSS. I don't need to inject javascript. Does that make it easier? Does that make it possible? =)
According to this documentation, chrome:// URLs are an invalid scheme so they won't be matched:
A match pattern is essentially a URL that begins with a permitted scheme (http, https, file, or ftp), and that can contain '*' characters.
I would look into using override pages instead.
As requested, here's my extension that can at least load when chrome://downloads is loaded, although as I said, I don't think you can modify the page even if you know that's the page you're viewing.
manifest.json
{
"name": "Test",
"version": "0.0.1",
"background_page": "background.html",
"permissions": [
"tabs"
]
}
background.html
<script>
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab)
{
if (tab.status == "complete")
{
alert(tab.url);
// should alert 'chrome://downloads' on that page. You can
// check for this url here and then do whatever you want
}
});
</script>
Update: Since Chrome 31 there is an API for extensions that allows access to Chrome's downloads: https://developer.chrome.com/extensions/downloads
There's also an API that allows access to list and manage other installed extensions: https://developer.chrome.com/extensions/management
(Previous Answer)
Unfortunately, there's not currently an API for Chrome extensions to access information about a user's downloads. It's a widely requested feature, though, and there's some discussion among Chrome developers here: http://code.google.com/p/chromium/issues/detail?id=12133
Star the issue if it's a feature that you'd like to see, and you'll receive email updates.
As this page shows, there is no API to override the downloads page... However, there is a way to make a file you have made replace the chrome://downloads/ page whenever it is loaded using javascript in your background page...
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab){
if(changeInfo.status === "loading"){
if(tab.url === "chrome://downloads/"){
chrome.tabs.update(tab.id, {url: "REPLACEMENT.html"});
}
}
});
Essentially what this does is - As soon as the page chrome://downloads begins loading (using the tabs.onUpdated API), the page is redirected to REPLACEMENT.html (Using tabs.update API)... There is no visible delay in the tab update
as this script is run before the chrome://downloads page begins loading... You can use a similar code in your file by pressing CTRL + U on the downloads page to view and copy its source code
