Meets my needs. 100%.

Millisecons-feature is also very useful.

Great idea! Easy to use. Good job!

My wish: customize output format in options (just enter a format string to override). Happy to contribute if that's welcome.

Simple and useful, exactly what I needed. Thanks!

the only epoch/unix timestamp-converter add-on i can find that displays in the context menu, which is great, but please add an option to add the millisecond converter to the context menu too!

Very practical add-on. But very nice would be to have a keyboard shortcut instead of right click and menu selecting.

Nice and simple. It would be great if this could also support millisecond timestamps (perhaps just assume milliseconds if the date is thousands of years in the future?). Also, is this open source? I'd be happy to contribute that feature.

It's very simple and useful, but not working on the built-in Firefox JSON viewer.

Good ad on so far
