A lifesaver! Had already procrastinated my whole day on this paper. Thanks to LeechBlock I didn't also procrastinate through the night. It's great as a small little reminder to get back to work when opening up Facebook's become so instinctual. I'm glad this addon made it through the switch to WebExtensions.

Would be nice to have a quick toggle for turning on/off different block sets rather than disabling the extension or messing with the when-to-block time period/limit logic.

Works well. A bit of UI work in the settings to make it less confusing to use would be nice -- but that doesn't make this addon less useful.

Best productivity tool! Thank you so much for updating to the new extensions API; I know it's not the easiest thing.

How do I begin to say how useful Leechblock is? It is by far the best tool out there to manage my internet use. It takes a little more to customize, but it's the best!

Wao, so nice to see it come back. Works like a charm

Glad to see a replacement for FF57. I noticed though that there does not seem to be a way to add a site to a blocklist if the list is marked as inaccessible during block hours. With the old leechblock I could click the toolbar icon and select "add to list" and pick one. Now, however, clicking the toolbar icon only takes me to a window to set up block lists with no option to add to a list that is locked.

Edit: thanks for the reply! I did see the add-on was labeled as experimental, just wanted to make sure this was noted just in case it was overlooked.

The new version is great and runs smoothly in Firefox 57+.

EDIT: Updated my review from 4 to 5 stars because the import/export settings feature is back. Yay!

Thanks for updating LeechBlock!

It blocks me from using time consuming websites too much. I love this addon
