Plenty of stuff on the Internet is written in traditional characters, so when I want to practice reading on some real text, I each time have to copy text to some converter and then get simplified characters.
It would be much better, if I had some addon in the browser that would do that automatically. I'd prefer something for Opera, which I use most often, but add-on for Chrome or Firefox also would be very nice.

Do you know anything like that?

And please don't tell me: "You just have to learn traditional characters, there won't always be an add-on around!" :P I'll get to that in the right time.

ChineseHacks wrote up an article on a good add-on for Firefox, check it out here:

Hope it helps!

Yup, that's the one that I had used, too.

That's really great, thanks guys :)
I love that it also enlarges text, miraculously perfect maladjustment between Latin and Chinese script really strikes my nerve.
