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.

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

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
