Seems t have stopped working on FF 45+ (Win10) Rated 4 out of 5 stars

Used this all the time; a great help. But hasn't worked since FF upgraded to v45

excellent addon, and useful Rated 4 out of 5 stars

what would rate this addon a 5-star is the ability to schedule websites monthly, as well as daily and weekly

Really usefull! Rated 5 out of 5 stars

It works just like it says, and does an excellent job at it.
Only thing it lacks is the ability to add a site and open it by some time interval, from like 8 AM to 8 PM. As now I have to do the scheduling manually which can be a bit tedious.
But other than that, it's just awesome.
If the developer can contact me and explain to me how I could do it I would be really great-full :)

Terrific! It is every well made and very useful. Rated 5 out of 5 stars

I can only begin to imagine the uses for this e.g.:

-Scheduling to open my bank account in sync with an auto-scheduled bill payment.

-Opening in time for their 24hr check-in policy (or at least before the deadline to do so)

-Sending me to a movie page in-sync with its DVD release date.

Thank you for making this add-on available.
