Unraveling the Mystery: Why `chrome.tabs.create` Acts Up on Mobile Chromium Browsers

Are you a Chrome extension developer frustrated by the quirky behavior of `chrome.tabs.create` on mobile Chromium browsers? Do you find yourself wondering why, despite passing `active: false`, the newly created tab becomes active anyway? You’re not alone! In this article, we’ll delve into the depths of this issue, exploring the reasons behind this behavior and providing you with solutions to tackle it.

The `chrome.tabs.create` Conundrum

The `chrome.tabs.create` method is a fundamental building block for Chrome extension developers. It allows you to create new tabs and customize their behavior. However, on mobile Chromium browsers, this method exhibits a peculiar behavior that can drive developers crazy.

When you call `chrome.tabs.create` with the `active` property set to `false`, you’d expect the new tab to be created in the background, allowing the user to continue interacting with the current tab. But, surprisingly, the new tab becomes active anyway, grabbing the focus and disrupting the user experience.

The Culprit: Mobile Browser Constraints

The root of this issue lies in the fundamental differences between desktop and mobile browsers. On desktop browsers, multiple tabs can coexist and be interacted with simultaneously. However, mobile browsers, due to screen real estate limitations and touch-based interfaces, adopt a more restrictive approach to tab management.

On mobile Chromium browsers, the browser’s primary goal is to ensure a seamless and distraction-free browsing experience. To achieve this, the browser implements various optimizations, including:

• Auto-focusing the most recently created or accessed tab
• Limiting the number of tabs that can be opened simultaneously
• Prioritizing the currently active tab above all others

These optimizations, while beneficial for the average user, can clash with the expectations of Chrome extension developers. When `chrome.tabs.create` is called with `active: false`, the mobile browser’s optimization algorithms kick in, overriding the `active` property and making the new tab active anyway.

Workarounds and Solutions

Don’t worry; all hope is not lost! We’ll explore some creative workarounds and solutions to help you overcome this limitation:

1. Utilize `chrome.tabs.update`

Instead of using `chrome.tabs.create` with `active: false`, try creating the tab with `chrome.tabs.create` and then immediately updating the tab with `chrome.tabs.update` to set its `active` property to `false`. This approach can help bypass the mobile browser’s optimization constraints.

chrome.tabs.create({
  url: 'https://example.com',
  active: true // Create the tab as active initially
}, function(tab) {
  chrome.tabs.update(tab.id, {
    active: false // Immediately set the tab as inactive
  });
});

2. Employ `chrome.tabs.query` and `chrome.tabs.highlight`

Another approach involves creating the tab with `chrome.tabs.create` and then using `chrome.tabs.query` to retrieve the newly created tab’s ID. Subsequently, use `chrome.tabs.highlight` to focus the original tab, effectively keeping the new tab in the background.

chrome.tabs.create({
  url: 'https://example.com'
}, function(tab) {
  chrome.tabs.query({ active: true, currentWindow: true }, function(tabs) {
    chrome.tabs.highlight({ tabs: tabs[0].id });
  });
});

3. Leverage `chrome.windows.create`

In some cases, you might want to consider creating a new window instead of a new tab. `chrome.windows.create` allows you to specify the `focused` property, which can help you achieve the desired behavior.

chrome.windows.create({
  url: 'https://example.com',
  focused: false // Create the new window in the background
});

4. Opt for a Hybrid Approach

Combine the above approaches to create a more robust solution. For instance, you could create a new tab with `chrome.tabs.create` and then use `chrome.tabs.update` to set its `active` property to `false`. If the user interacts with the new tab, you can use `chrome.tabs.highlight` to refocus the original tab.

chrome.tabs.create({
  url: 'https://example.com',
  active: true // Create the tab as active initially
}, function(tab) {
  chrome.tabs.update(tab.id, {
    active: false // Immediately set the tab as inactive
  });
  
  // Listen for tab updates
  chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
    if (tabId === tab.id && changeInfo.status === 'complete') {
      chrome.tabs.highlight({ tabs: originalTabId });
    }
  });
});

Conclusion

In conclusion, the quirky behavior of `chrome.tabs.create` on mobile Chromium browsers can be attributed to the browser’s optimization constraints. By employing creative workarounds, such as using `chrome.tabs.update`, `chrome.tabs.query`, `chrome.tabs.highlight`, and `chrome.windows.create`, you can achieve the desired behavior and provide a seamless experience for your users.

Remember, the key to overcoming this limitation is to think outside the box and adapt to the unique constraints of mobile browsers. By doing so, you’ll be able to create exceptional Chrome extensions that cater to a wide range of users, regardless of their device or browser type.
