I have the same issue as others, the timer is reset to 15 minutes every time I relaunch Firefox. It is really annoying... Is there a Github repo linked to this app so I can modify it?

This could be a very useful add-on, however, when I select another interval it works for this session, but it defaults back to 15m on the next session. Please fix this!

This could be a very useful add-on, however, when I select "1 hour" as time gap I still get *multiple* reminders per hour. So the interval setting isn't working (I tried reinstalling but without success). Please fix this!
