Hi, this is still WIP, just trying to upload something already. Having trouble with using JS fetch().
I get this:

Failed to load resource: the server responded with a status of 401 (Unauthorized)

So it doesn't seem like it's accepting the cookies, or the JS fetch() doesn't pick them up, I used this as you can see it in the code:

fetch(fetch_url, {credentials: "include", mode:'no-cors'})

Never used it before, neither touched a Chrome Extension before @Athou . Any suggestions? Thanks!

I don't know :( When I wrote the extension, fetch() didn't exist yet and I had to use the old XMLHttpRequest API, which passed the cookies correctly (see https://github.com/Athou/commafeed-chrome/blob/master/background.js#L7)
