Tesla's In-Car Browser Just Got a Big Upgrade: Bookmark Sync, Video Calls and Full-Screen Streaming

Tesla's built-in browser has always been the feature everyone forgets about until they're sitting at a Supercharger with 20 minutes to kill. The 2026.26 Summer Update changes that. According to NotaTeslaApp, this release delivers what may be the biggest set of browser improvements Tesla has ever shipped — including camera and microphone access for video calls, bookmark syncing across vehicles, larger default content, and full-screen playback on more streaming sites.

If you spend real time parked in your car — charging, waiting on school pickup, working between meetings — this one is worth reading through.

Video Calls Are Now Possible in the Browser

The headline feature: websites can now request access to your Tesla's cabin microphone and interior camera through the regular browser. An on-screen prompt lets you approve or reject each request, and camera access stays limited to when the vehicle is parked.

That opens the door to browser-based video calls on platforms like Microsoft Teams, Google Meet, Discord, and Slack. NotaTeslaApp tested it and reports the video feed automatically crops to focus on the person in the driver's seat.

Previously, Zoom was the only service allowed to use the interior camera — and it ran as a special borderless browser rather than the normal one. Now Tesla has opened the capability to any web platform. If you want to try it without logging into a service first, WebcamMicTest.com is an easy way to confirm your mic and camera are working.

One important caveat: this feature is limited to AMD Ryzen vehicles, thanks to the more powerful infotainment chip.

Bookmarks Now Follow You Between Teslas

Your saved sites now sync across vehicles tied to the same Tesla Profile. That means the bookmarks you set up in your daily driver can show up in a second personally owned Tesla, a rental, or a service loaner.

Favorites and frequently visited sites on the new tab page are saved per driver profile, and you don't have to enable anything — if you're using a Tesla Profile, it happens automatically.

Bigger Default Zoom (With One Trade-Off)

Tesla's browser is Chromium-based but still doesn't let you manually adjust zoom. With the Summer Update, Tesla raised the default zoom level, so text, images, and those frequently visited site icons all render larger and are easier to read from the driver's seat.

The trade-off: because the usable page area now appears narrower, responsive sites like X and YouTube may load their tablet- or mobile-style layouts instead of the desktop version.

More Full-Screen Video, Unofficially

Tesla Theater still only officially supports a handful of video services. But the browser now automatically goes full-screen when you visit specific streaming websites — HBO Max and Prime Video among them.

It's effectively a wider Tesla Theater experience through the back door. The limitation remains that you still can't play these services on the rear screen without a workaround. NotaTeslaApp is hopeful this signals Tesla will either add these services to Tesla Theater directly or open Theater up the same way it just opened up mic and camera access.

Tesla also likely updated the browser's underlying Chromium version, which brings bug fixes and 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.

What This Means for How You Set Up Your Car

A browser you can actually take video calls and watch movies on changes what your cabin needs to do. A few practical things worth sorting out before you lean on these features:

• Sound quality matters more now. If you're joining Teams or Meet calls from the driver's seat, cabin acoustics and speaker settings suddenly count. Park somewhere quiet and test your setup before an important call.
• Charging while you stream. Full-screen video and video calls run off the main pack. If you're using the car as a parked workspace, keeping a portable Level 1/Level 2 charger or the right adapter in the trunk means you can top up at any outlet instead of watching range tick down.
• Cabin lighting for video calls. The interior camera crops to the driver's seat, but it can't fix backlighting. Parking with light in front of you — not behind — makes a bigger difference than any accessory.
• Phone and passenger comfort. Longer parked sessions mean more time in the seat. Sunshades, seat organizers, and a solid phone mount all pull their weight when the car doubles as a lounge or office.
• Check your hardware first. The camera and mic feature only works on AMD Ryzen vehicles, so confirm which infotainment computer your Tesla has before planning around it.

The Bottom Line

Tesla has spent years treating the browser as an afterthought. The 2026.26 Summer Update finally treats it like a real platform — synced bookmarks, readable text, working video calls, and full-screen streaming on more sites than Tesla Theater officially supports.

For owners who already use their Tesla as a mobile office or a movie theater on wheels, this update makes that setup meaningfully better. Pair it with the right charging gear and cabin accessories, and parked time stops feeling like downtime.
