I love the idea so much that I even have opened Firefox for it ;) (Chrome extension would be superb!)

This is a brilliant extension. Thank you!

I’d love an update which put a grey background or something behind white text ;)

Nothing wrong with Firefox, not even with Firefox only, still my favourite development tool. Developers should test crossbrowser anyway should at least have it on disc. What is it every dev seems to use Chrome only?

Nice article too :)

Thank you! I just, today, decided I needed this tool. And now, OP has delivered. Thank you thank you thank you.

Great article! I will be watching for the Chrome version of Type-o-matic for sure.

What a great article and tool :)
This will come in very useful ~ thank you.
