Tesla’s 2026.26 Summer Update includes several features that improve the vehicle’s web browser. While the highlight is microphone and camera support that lets you use Microsoft Teams, Discord, and Slack for video calls, it also includes other improvements, including bookmark syncing and a new default zoom that makes content larger.
Camera and Microphone Access
Websites can now request access to the vehicle’s cabin microphone and interior camera through the regular Tesla browser. The camera remains limited to times when the vehicle is parked, and an on-screen prompt lets the user approve or reject each request.
This opens browser-based video calls to services such as Microsoft Teams, Google Meet, Discord, Slack, and more. We tested the feature, and the video feed is automatically cropped to focus on the person in the driver’s seat.
Previously, Zoom was the only service allowed to use the interior camera. However, Zoom was only a borderless browser, so now Tesla is expanding the feature to work with any web platform.
If you’re curious about the implementation without logging in to a service, a great way to test it is to go to WebcamMicTest.com, where you can test the mic and camera.
This feature is limited to AMD Ryzen vehicles due to their more powerful infotainment chip.
Browser Bookmark Sync
Another feature (thanks, James!) added to the browser with this update is the ability to sync Tesla bookmarks across your vehicles. Saved sites can therefore appear in another Tesla using the same profile, including another personally owned vehicle, a rental, or a Tesla loaner.
Favorites and frequently visited sites that show up on the new tab page are saved per driver profile. To sync bookmarks, you don’t have to do anything. The process happens automatically if you use a Tesla Profile.
Browser Zoom
All modern browsers have a zoom feature you can use to make content larger or smaller on any web page. Unfortunately, the browser in a Tesla, even though it’s based on Chromium, doesn’t support manually adjusting the zoom level.
With the Summer Update, the default zoom level has increased, making content look larger, like those frequently visited site icons. This change will make images and text on any website larger and easier to see. However, it can also cause responsive websites such as X and YouTube to load a tablet- or mobile-style layout because the available webpage area appears narrower.
More Tesla Theater Support
This update also adds support for full-screen playback on several video streaming sites. While Tesla Theater only supports a handful of video services, Tesla now makes the browser go full-screen when you visit specific video streaming websites, like HBO Max, Prime Video, and more (full list here).
This effectively increases support for Tesla Theater, though you still can’t play these video services on the rear screen without this workaround.
We’re hopeful this change means Tesla will either add these new video streaming services to Tesla Theater or open up support for Tesla Theater as they did with mic and camera support in the browser. This would allow anyone to add bookmarks to Tesla Theater for their preferred video services, which is what those icons are today.
Tesla likely also updated the underlying Chromium version of the browser, which fixes bugs and brings support for newer HTML standards.
These updates make Tesla’s built-in browser more capable and more user-friendly, and they’re some of the biggest updates we’ve ever seen to Tesla’s browser.
