I just searched (without any luck) for the Ctrl button on my TV remote. That's how addictive Mozilla Firefox tabbed browsing is.
I really need tabbed TV surfing too. My TV does not have teletext/videotext memory, so I loose videotext browsing state on each channel change. That's really annoying, since videotext updates are so slow that I always switch to image while waiting for the weatherreport or the latest scores. I only have channels with nothing good on, så I always change the channel having forgotten about the videotext loading and am left informationless.
