I love this extension. I've been using this for years to help with accessibility testing and highly recommend it to all of my colleagues.
thx a lot!
tốt hữu ích
Awesome.
Very nice tool!!
Siempre la instalo, cada vez que empiezo con una nueva pc incluso VM, despues de instalar Chrome instalo esta extensión.
No funciono ninguna opción en Microsoft Edge versión Versión 83.0.478.58 (Compilación oficial) (64 bits). Hecho gracias al proyecto de código abierto Chromium y a otros softwares de código abierto (edge://credits/)
In new versions of Chrome, new extensions do not appear in your toolbar. That means that extensions you install are not readily visible. You have to fish around to "pin" them. I think some kind of post-install explainer would help this obvious UX issue with Chrome.
I'm using it for years. Thank you!
