Folks reporting this is now broken would be more correct in saying that how it works has changed. Use the "annotate article" from the plug-in drop down to get refreshed view of the page you want to annotate (w/o the site style sheet). Admittedly not as groovy as before but all my content and ability to make more is there. It's a great tool and concept!

I've used Diigo for years and transfered to a new computer. I had trouble logging in and saving. These are the steps I took:

1) Logged in at diigo.com
2) Downloaded through diigo.com link
3) Disabled enhanced tracking protection (unfortunately, the extension wouldn't work without doing this)

Me dejo de funcionar y no se porque desapareció de mi barra de tareas en Mozilla Firefox. Peor la mande a la papelera , la instale de nuevo, firme mi registro con mi clave y funciono de nuevo por lo que estoy muy contento

Excelente servicio y extensión, me resulta imprescindible. Uso Diigo desde sus comienzos y sigo siendo un usuario agradecido.

Excellent for research as so much information is today published online.
