Nice! Wish Mozilla would build this one in. :)

This just works, 100!

Works as expected. Very useful the little fav-icon icons were bugging me so thank you!

Quick Easy and just works.

Thank you.

Checkmarks, Where have you been all my life!!!
Bloody brilliant.

As someone who wipes their PC every so often and then installs Firefox this is great. I despise how Firefox cannot sync the favicons so I would have to manually open each website myself in my bookmarks. This just saves me so much time and prevents me from getting a headache. Well done.

Needs a sign-in on Google before running but gets most icons. Still worth 5 stars.

Sencillamente la mejor extensión que he probado para actualizar los marcadores, los favicons y eliminar url's obsoletas.

Enhorabuena al creador.
Muy recomendada!
