This looks like a really cool addon, but sadly the timer itself isn't working. Tho I can see what websites I have visited. If you have any suggestions for help I'd love to hear it!

EDIT: I'm not sure if restarting did the trick, or if I was just confused by the UI showing only minutes but no indication it's actually ticking by. But it seems to be working now

Excellent addon! Really disturbing (but in a useful way)
Actually, it would be good if numbers on counter be bigger.
And if you could have both options "time spend online" and "on which sites" in the same time.
Still it's a good addon I'm glad I found it! Thank you!^^

Doesn't work properly for some reason.

The idea is excellent

Doesn't seem to work. Icon visible but no time. Summary page is blank & menu doesn't work. Ironic that an add-on designed to stop wasting time actually does the opposite.

This has instantly become one of my favourite extensions.

I wish the metrics page had an 'auto refresh' option, but the fact there is no such option is probably a firefox security limitation.

Best time control addon

Good stuff, just needs more customizability options like other reviewers say like with the idle time out.
