Sim excelente extensão. Mas permita-nos uma sugestão PARA MELHOR SEGURANÇA E EFICÁCIA: poderia ser ainda melhor se..
Excelente. Mas por que não fazer a apresentação do IP de forma direta e clara ao lado da barra de endereços - inclusive na cor vermelha - e deixar as demais informações para serem obtidas ao clicar? Segurança antes de tudo - IP notificado de forma direta sem necessitar de cliques. Como exemplo apenas, o antigo "ShowIP" até a versão 2.7.7.1 apresentava direto o IP da página em vermelho, sem necessidade de busca e clique.

Yes excellent extension. But allow us a suggestion FOR BETTER SECURITY AND EFFECTIVENESS: it could be even better if ..
Great. But why not make the presentation of the IP directly and clearly next to the address bar - including the red color - and leave the other information to be obtained when clicking? Security before everything - IP notified directly without needing clicks. As an example only, the old "ShowIP" until version 2.7.7.1 presented the IP of the page in red, without need of search and click.

The biggest draw to this add-on is its simplicity. I was wondering if you might be able to configure it to display the IP at all times in the menu bar, without needing to click the 'I?' icon. The only add-on I knew of that did this, no longer works with the most recent Firefox update, and none of the available add-ons appear to offer this feature. That being said, you could potentially attract a number of new users, as I know I'm not the only one looking for this. Anyway, other than that no complaints. It's simple, and works as advertised. :)
