title: how to configure live server extension in vscode linux to open new instance in already open browser window
body: <p>i am trying to configure my visual studio code(installed on ubuntu 18.04 LTS). i use <a href="https://marketplace.visualstudio.com/items?itemName=ritwickdey.LiveServer" rel="nofollow noreferrer">live server extension</a> developed by <a href="https://marketplace.visualstudio.com/publishers/ritwickdey" rel="nofollow noreferrer">ritwick dey</a> to render my web page dynamically. but every time i run live server extension, it opens a new window of firefox (my default browser) that it attaches with visual studio code as a new window. But i want the live server(extension) to open a new tab in the already open browser window. I remember that in windows 10 OS live server opens a new tab in already open browser window. Is there any workaround that i can do to achieve the same result ?</p>
  <p>here is <a href="https://i.stack.imgur.com/ERYjw.png" rel="nofollow noreferrer">my vscode settings</a> that i use globally. and here is the <a href="https://github.com/ritwickdey/vscode-live-server" rel="nofollow noreferrer">source code of live-server extension.</a></p>
  <p>thank you.</p>
