Good stuff with a lot of settings but I'd like some features like a timer on the blocked pages for the blocking period, and the ability to view current blocks on the tray icon

Perfect. Special thanks for nifty options like requiring a random 128 char token displayed as an image to access the add-on settings. Combine it with Firefox Policies and you can't even uninstall or disable the add-on. Lovely.

My favourite web blocker. Highly customizable. You can even set time-limit resetting every two hours or every week.

absloutly recommend it to anyone thats looking for a little control over their browsing habits :)

It reminds me how much time I have used for certain kinds of time wasters and eventually blocks the sites. I have been looking for an option less intrusive than blocking sites in the router, and this fits perfectly. I think funktionality like this, healty surfing, should be a built-in in the browser. As it stands I can see that Leechblock have some issues accurately calculate the number of minutes on a certain site. A built-in could help that.

A marvelous app!

I've got a bad habit of opening some websites when I'm distracted. Now I get to see the blocked page which asks me to write a review. So I'm doing that instead of being productive.

Great add on, rich feature set, loving the "delay" feature. The UI is a bit clunky but it works.
