Hey,
I am wanting a custom firefox / chrome extension that when you type subreddit in the URL bar it auto takes you to the sub.
For example if I type r/memes in the URL bar it'll take me to https://reddit.com/r/memes

Thanks,

Verstappen

Sure, it's possible to create a custom Chrome extension that redirects you to a subreddit when you type it in the URL bar. Here's one way you could do it:

Create a new directory for your extension, and within it create a file called "manifest.json" with the following contents:

JSON:

{
  "manifest_version": 2,
  "name": "Subreddit redirector",
  "version": "1.0",
  "background": {
    "scripts": ["background.js"]
  },
  "permissions": [
    "activeTab"
  ],
  "chrome_url_overrides": {
    "newtab": "newtab.html"
  }
}

2. In the same directory, create a file called "background.js" with the following contents:

JavaScript:

chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
  if (changeInfo.url) {
    var regex = /^https?:\/\/(www.)?reddit.com\/r\/([^\/]+)/;
    var match = changeInfo.url.match(regex);
    if (match) {
      var subreddit = match[2];
      chrome.tabs.update(tabId, {url: "https://reddit.com/r/" + subreddit});
    }
  }
});

3. Finally, create a file called "newtab.html" with the following contents:

HTML:

<!DOCTYPE html>
<html>
  <head>
    <title>New Tab</title>
  </head>
  <body>
    <h1>Welcome to your new tab!</h1>
    <p>Type a subreddit name in the URL bar to go to that subreddit (e.g. "r/memes")</p>
  </body>
</html>

To use your extension, go to chrome://extensions in your Chrome browser, enable "Developer mode" in the top right, and then click "Load unpacked" and select the directory you created for your extension. Now, when you type a subreddit name in the URL bar, it should automatically redirect you to that subreddit.
