chrome-extension | The OwnPass Chrome extension | Browser Plugin library

I am a python developer, but there is a small part that I need to complete in Javascript, I am unable to figure it out.

This needs to be done in a local computer only. I have a .csv file with two columns, and I Need to make a real-time line chart (it reads csv file every X seconds and refresh).

I tried some code from online, they work only with real url. My file is local, so I get this error in all the code I tried by copy/pasting.

Access to XMLHttpRequest at 'file:///C:/Programs/Stock/test.csv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.

It would be great, If someone can help me with this, otherwise I need to learn Javascript from scratch.

I'm trying to fetch from the server an audio wav file, and play it in the client with the element.

I created a simple project with Vue.js 3 + Vite + PrimeVue.

So far everything works like a charm when I'm developping and if I'm serving the build (i.e. /dist) with a server.

But I wanted to see if I could open the /dist/index.html directly from my browser... I mean it should be possible, technically-speaking.

Here are below the bits of configuration:

I am trying to figure out how to change images of a website using chrome extensions that aren't just ones with "src" attributes. In my case, I am trying to change the logo on https://www.foxnews.com/ and I can see when I inspect and look in "styles" that it is the "background-image" property. The problem is that when I set it to my own image (using methods that have worked elsewhere before), nothing happens. I can change the "background-size" and "background-color", but the image will not budge. Can someone please provide a solution?

Here is my code so far: manifest.json:

Apparently, scripts in HTML template only work in HTML template itself, and not the page that the HTML template is injected into. (The scripts still execute, but they rely on jQuery, and even though its imported before the others, it spits out errors.)

To elaborate, here is my code:

I have an unlisted extension published through the Chrome web store which is already being used. I have a new version which I would like to release just to testers initially, before a full roll out to everyone. Can this be done?

The same thing has been asked here but it was almost 9 years ago, and the answers disagree on whether it's possible or not: How to publish new version of Chrome Extension only to testers

To elaborate, I am injecting and loading an HTML template in my Google Chrome extension like this:

I'm trying to open BlueJean after a link in my browser. I get prompted if I wanted to let xdg-open open an application for the url, I agree and click the button. However, the right app is not opened and a default app opens up doing nothing. Basically, a new window is opened for my browser as the the link passed is basically an url.

The error shown on console is
