Carolina Aguilera (ID: 0000007970009917) Voted 2 ★ - Updated 05/15/2023 Antes aportaba información de calidad al hacer la revisión y ahora la experiencia usuaria con la interfaz de la extensión al activarla es horrible. ¿Qué sucedió en esta nueva versión? Se fue eliminada de mis herramientas de revisión de accesibilidad. Fuiste bueno Siteimprove.

Earl W (ID: 0000001535d7f2f7) Voted 2 ★ - Updated 04/16/2023 V1 was good. This version does not work well, and I don't use it because the errors do not load for me. I only see the Spinner which does not stop. I quit after 40 seconds.. I with they would go back to version 1 so I can use this again, but for now I'll pass.

Christopher Sheldon (ID: 000000ea08f84521) Voted 2 ★ - Updated 01/09/2023 I really liked v1.x but I have noticed that v2 has obvious errors and things it is not finding in pages. It is beyond the rules being refined in this version. One example that made me take notice was a page that had dark grey text on a darker grey background that was obviously a contrast fail, followed by a dark blue "Read more" link that also was an obvious fail. The extension only called out the grey on grey and didn't seem to notice the blue on grey fail in an anchor adjacent to the grey text for any issues. When manually checked the contrast was below the 4.5 ratio so failed AA and AAA contrast guidelines, possibly also AA and AAA Link Purpose. Finding these errors in the extension has shown me it is not as reliable as the previous version at finding issues. Be careful if you are using it to scan your site as it could be missing obvious fails.

Thomas IX Days (ID: 000000d946959e11) Voted 5 ★ - Updated 08/11/2022 Hello, I can't find documentation if this plug-in works at checking ADA accessibility for mobile devices if I use the plugin while using the developer tools (Responsive Views) on a Chrome browser. It's been frustrating find information about this.
