Chromium/Firefox extension - Typescript

Posted 4 weeks ago

I am building a firefox and chromium extension that will be published on the two different stores.

I've started a bit with Plasmo with TS but Plasmo is no requirement:

What to do (features):
- An simple but nice UI (popup) that allows you to opt-in or opt-out of the different features stated below. Also warning texts etc if needed.

- Get all cookies from, as long as you're logged into and post that to our server.
- The same as above but client-sided, so it will not post the cookies to us - instead run the logic in the extension and post the response to us.
- "List on CSMiddler" button on inventory-page.
- Some new query parameters for tradeoffer-page to auto prefill e.g description and items to give/receive.
- Warning if any page stating that they are a site but isn't (AKA same UI etc) - a so called phishing site.

Requirements from your end:
- Send me proof that you have experience with addons/extensions, for example an URL to github and Google chrome extension store of an extension you've developed.
- Include "yes - I read everything" as the first sentence of your message to me here on Upwork, that way I know you read all the specs ;) (and can filter out the rest)
- Estimate of time (x hours) of all tasks stated above
