It's really great! One thing: I have not been able to figure out the active time intervals. Maybe it's me or maybe it's not working. Other than that, this is great!

for simple on/off blocking this is fine, but the scheduling functionality does not work

good

Does everything it says it does perfectly.

It works.

It doesn't work. That's all.

I'm using this extension to prevent myself from wasting time in social media when I should be thinking about my work. Hopefully I resist the temptation to disable this addon :P

very nice.

Excellent! I'm using this to never let anything Yahoo onto my computer. They have snuck in one time too many.

Works fine, but only if ONE firefox window is open. It works on only one window when multiple firefox windows are open.

Its really awesome. I am now less distracted and focus on my work. Thanks a lot.

Very helpful.

It's a nice add-on!
But you should add more options to be exported to .CSV file, like time interval,..
And you should sync settings between default mode and Private Browsing mode (incognito). Because on my computer, it's not the same on 2 modes and I must set again on Private Browsing mode.
BTW, your work is nice, keep going!!!

Everything working fine. Its what I was looking for to increase productivity. Reaaly good option for me it set up block time (I blocked social media at working time, and unblocked at afternnon)

Too easy to unblock sites.

Keep the unblocking process time consuming.

It is rather a very poor user experience to ask him/her to type the url. Why not design this add-on to allow to add it by click on the tab and extract the site info directly?
Also, I noticed that typing the domain like domain.com won't block landing.domain.com. What is the point then? The malicious web site admin can create a second site like landing2.domain.com and go on business as usual.
I really liked to try this add-on at first because I wanted to avoid editing the hosts file directly.
I would appreciate if the developers listed to this feedback.

Great extension, only down side is that there is no way to reset the number of times you've attempted to access a blocked site without uninstalling and reinstalling. But besides that, it works amazing, would highly recommend.
