As a long term user of the LeechBlock add-on, I was really amazed by simplicity and ingenuity of Intention. Intention delivers the best productivity features in a simple package. Easy to setup, easy to use, does its job well without need for additional tweaking. Now I can have YouTube effectively blocked for mindless browsing, while still comfortably use it for listening to the music. Thanks to Intention, I can also accesss Facebook Messenger for a minute to quickly reply to my student, but having it effectively blocked for long-term chat sessions with my friends and family. Brilliant UX design.

perfect

Easy to use, does exactly what i want it to do.

i like the addon, but I'm concerned about why does it need to "Access your data for all websites"?

This is a well made app and does what it does very well. it keeps track of the time you spend on sites you whitelist in the extension page and forces you to acknowledge how much time you're spending on these sites. Recommended! I especially love how it blurs the site in the background instead of taking you to a new tab. Aesthetic and functional.
Just one small feature request for the dev: add an option to play a game before selecting a time to unlock a site for. It's too easy to just select a time limit and keep on browsing; i would like for example the user to write a sentence in order to unlock the ability to extend the time.

Super useful plugin! It helps a lot to keep procrastination under control, specially those days that I am more tired than usual.
