Don't even give this a try, you'll regret it

It is so good, I made a new account just for this review.

What is the message "All tabs hidden" for?
What a genius idea is to hid all tabs and about it to everybody. Haha

It's not restored when it have other open tabs.

1 star Less because it just need to set an alternative page for hidden tab , or other will know that you are hiding something, else it's awesome.

Su firefox non si puo impostare una keyboard shortcut

Very useless if you cannot set an alternative page that is displayed when you click on the panic button and everyone can see that you just pressed it!

Look mama, no porno!. it works just fine....

It does not hide but closes all tabs

Cierra todas las pestañas y no las recupera. Es un botón de pánico sin más. Prácticamente como cerrar el navegador.

I was looking for something similar to the panic button that the chrome web store had and this was is exactly like the one I had. It works fast and helps when you want to quickly hide certain web pages from people.
