The first TVs powered by Mozilla's Firefox OS are now on sale.
The Panasonic Viera TVs are optimised for HTML5 to make them more compatible with web apps.
The user interface is also customisable, so you can arrange it how you see fit, and allows quick access to favourite channels, apps, websites and content stored on other devices.
Like Mozilla's Firefox browser, Firefox OS is completely open source, opening up the possibilities.
Pretty much anyone who's a dab hand with a bit of code can make web apps for it, much like Google's Android mobile operating system.
The Panasonic Viera models are the CR850, CR730, CX800, CX750, CX700 and CX680.
You can buy them from Currys PC World, among other places.
Masahiro Shinada, director of the TV business division at Panasonic, said Firefox would provide the firm with a "differentiator in the smart TV market".
"We're happy to partner with Panasonic to bring the first smart TVs powered by Firefox OS to the world," added Andreas Gal, Mozilla's CTO.
"With Firefox and Firefox OS-powered devices, users can enjoy a custom and connected web experience and take their favourite content (apps, videos, photos, websites) across devices without being locked into one proprietary ecosystem or brand."
