Chrome tabs and Google Workspace for Education

[Darin Clausing]

Hi everyone,

I wrote a chrome extension that basically checks for "about:blank" tabs and tabs with "unblocked" in the title. The reason is there are many unblocked games sites that bypass our filters and also sites that imbed content in about:blank which our filters can't block. The extension works fine when I install it locally (manually) but it seems to be inactive if I force install it via the Google Admin Console. I am wondering if something is wrong with my code that would make it glitch when deployed. Here is the code I am using and I would appreciate any and all assistance.

Here is my manifest.json file code:

{

  "manifest_version": 3,

  "name": "SUSD Tabs Be Gone!",

  "version": "3.0",

  "description": "Automatically closes tabs named 'about:blank' or with the URL 'about:blank' and closes tabs with unblocked in the title.",

  "permissions": ["tabs"],

  "background": {

    "service_worker": "background.js"

  }

}

And here is the background.js

// Function to close tabs with about:blank URL or title or containing "unblocked games"

function closeTabs() {

  chrome.tabs.query({}, function(tabs) {

    // Loop through all tabs

    tabs.forEach(function(tab) {

      // Check if the tab's URL is "about:blank" or if its title is "about:blank" or contains "unblocked"

      if (tab.url === "about:blank" || tab.title === "about:blank" || tab.title.toLowerCase().includes("unblocked")) {

        // Close the tab

        chrome.tabs.remove(tab.id);

      }

    });

  });

}

// Function to reload the extension

function reloadExtension() {

  chrome.runtime.reload();

}

// Event listener for when the extension is installed

chrome.runtime.onInstalled.addListener(function() {

  // Close existing tabs on installation

  closeTabs();

  // Schedule closeTabs() to run every 30 Seconds (30000 milliseconds)

  setInterval(closeTabs, 30000);

  // Schedule reloadExtension() to run every 30 Seconds (30000 milliseconds)

  setInterval(reloadExtension, 30000);

  // Event listener for tab updates

  chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {

    // Check if the tab's URL is "about:blank" or if its title is "about:blank" or contains "unblocked games"

    if (tab.url === "about:blank" || tab.title === "about:blank" || tab.title.toLowerCase().includes("unblocked games")) {

      // Close the tab

      chrome.tabs.remove(tabId);

    }

  });

});

Thank you,

Darin

You should put "chrome.tabs.onUpdated.addListener" at the top level, rather than put it in the callback of "chrome.runtime.onInstalled.addListener".

I also suggest removing the code of "setInterval()" and "reloadExtension()".

Thank you Jackie,

I will make the suggested changes and submit to review to see if it works with being deployed via the Google Admin console. (I made the changes and it works as a stand alone install)
