Awesome and simple add on, accurately measures my time tracking need.

It tracks your total browsing time and gives you occassional alerts. It's very useful!

Simple, efective, free. The best over all.

Perfecto para saber si usamos bien el navegador web, para así no perder el tiempo en la web!

very cool add

Top extension!

Useful addon, easy to use

Easy, useful and minimalist GUI. Great Work !

Lovely and simple. I did a brief code audit to confirm it only stores information offline and doesn't ping a remote server for any reason.

IF YOU HAVE PROBLEMS GETTING EXTENSION TO WORK: Remove from firefox, completely reinstall and when reinstalling, DON'T allow to run in incognito tabs. If you do this everything should work just fine, if not keep reinstalling until it does.

It is working, if you have problems try removing and downloading again, worked for me.

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!^^

The idea is excellent
