DID NOT WORK AT ALL!! Rated 1 out of 5 stars

this add on did not work for me at all!!
it said that I had no unread messages while facebook said I had several unread messages from two different people. I was very disappointed with this add-on and definitely would not recommend it as it did not work at all!!

Es bueno, el botón de marcar como leídas funciona bien si es necesario.

Rated 2 out of 5 stars

if only there was a toolbar button to easily turn it on/off,
it's really annoying to have to go to addons manager and search through hundreds of addons just to disable it

re: mark as read Rated 5 out of 5 stars

Manual Mark As Read seems to work just fine (or as well as it ever did before using the extension). Mark as one would normally.

Nice add Rated 2 out of 5 stars

but the problem how to mark messages as read ?
