Description from store LeechBlock NG (Next Generation) is a simple free productivity tool designed to block those time-wasting sites that can suck the life out of your working day. (You know: the ones that rhyme with 'Blue Cube', 'Space Hook', 'Sticky Media', 'Quitter', and the like.) All you need to do is specify which sites to block and when to block them. You can specify up to 30 sets of sites to block, with different times and days for each set. You can block sites within fixed time periods (e.g., between 9am and 5pm), after a time limit (e.g., allow up to 10 minutes in every hour), or with a combination of time periods and time limit (e.g., allow up to 10 minutes in every hour between 9am and 5pm). Additional features: • Lockdown: Block sites immediately for a specified duration. • Access control: Set a password or random access code for the options page, to slow you down in moments of weakness! • Delaying: Set a countdown to delay access to sites instead of completely blocking them. • Wildcards: Block a range of sites (e.g., *.somesite.com). • Exceptions: Whitelist sites you don't want to be blocked (e.g., +allowedsite.com).

  • (2021-05-06) Marie Zelenkova: Already using this extension with Firefox for Android and also for Chrome Desktop. For my phone, it was the best solution, as I did not want to download suspicious apps and give them permissions. Your extension was a lifesaver 🖤 I appreciate that your code is publicly available.
  • (2021-05-03) Robert Iczek: This extension is great, but when I type in a time period for example 2350-0700 and click Save Options, those hours delete themselves. [EDIT] Okay, it worked, thank you.

  • (2021-04-27) ori x: Helps concentrating, easy to use. Thanks!
  • (2021-04-27) Navya: Does its job well, and can block the sites. Only problem, I have to reload the page for the block to come in effect when the site is previously open.
  • (2021-04-22) Mohammad Naser: this helped me to not get distracted with roblox even in school this thing gave me higher grades
  • (2021-04-19) enrico aranha: The best site blocker of all, and it's free to use! Thanks for this amazing chrome extension!
  • (2021-04-19) Juan Carlos Gonzalez: Muy útil, pero no muy intuitiva. La extensión es muy buena, se puede configurar por horario e incluso se pueden crear varios "bloques" dependiendo de los días que se necesiten, algo útil si eres estudiante, pues puedes programarla en el horario de tus sesiones de estudio o clases. Tiene muy buenas capacidades, se puede filtrar por sitio, por palabras clave, se pueden hacer excepciones e incluso se pueden bloquear todos los sitios y dejar únicamente sitios permitidos o palabras permitidas. Sin embargo la interfaz no es tan fácil de usar y está en inglés
  • (2021-04-17) David Desmond Joy: I was trying to find an effective way to block msn.com after I log out of outlook.com, and this great piece of software works! Wow it has a lot of flexibility and its free! Thank you, James Anderson and team!
  • (2021-04-17) Ali Havasi: Free, effective and easy to use.
  • (2021-04-16) Lara Mae Lumbres: I need something that will still give me access to the site every hour but at a limited time and this is exactly what I need! thank you for making this!!!

  • (2021-04-14) Vishesh Varshni: i love you , you people are the best , you are the TIME SAVERS !!!!
  • (2021-04-12) I spent an hour looking for a simple extension that will allow me to block some sites. It was unbelievably hard to find something that is free. Most of the apps charge around 7-8 bucks per month. Are you kidding me? This is how much I pay for an app to learn chinese. Thank you for creating this app and helping people combat their addictions (like in my case is social media)
  • (2021-04-11) Geet Kamal Tej Dandu: Excellent app for absolutely free of cost. Thank you so much. I'm loving it!
  • (2021-04-09) Dominik Majek: Absolutely the best website blocking app I know of! You can set a schedule as well as simply block sites. It has tons of features that you won't find anywhere else. Plus, it's TOTALLY FREE! I assure you that you will not find anything better ;)
  • (2021-04-09) Under Lock: Одна из немногих штук, помогающих моей продуктивности не скатиться под плинтус :)
  • (2021-04-09) Ali B: Honestly what got me through online school. Prevented me from watching tiktok and youtube during zoom.
  • (2021-03-31) Ivan Sterligov: waaay too much self-promotion in this app.
  • (2021-03-29) Juan David Gil: The most flexible and powerful site blocker I could find. Excellent.
  • (2021-03-29) RAVI MEHTA: best extension for blocking unwanted sites PERIOD.
  • (2021-03-28) Aziz Koç: I think its based on StayFocusd but comes with versatile set of features including very detailed scheduling, site sets and nuclear option. Simple and perfect
  • (2021-03-27) Kevin Duran: a GOAT blocker

  • (2021-03-17) Lou Cornum: Easy to use and has already helped me a lot. I would definitely recommend and do to my colleagues and fellow writers.
  • (2021-03-13) Jerren Sia: nice extension... this saved me from sites which are making me do (whatever but its not good). this is not only for procrastination elimination but for to stop doing things! my only suggestion is to make it possible to make this extension password protect the extensions screen so that you cant disable the extension. they said its free and will always be. and the 'end of time' humor is quite funny! nice job leechblock dev
  • (2021-03-12) Joel Pak: this does for free what other applications charge you $10+/month for. Takes about 10 minutes to set it up and you're good to go. Highly customizable for all your anti-procrastination needs.
  • (2021-03-12) Thibault Lebrun: Very useful and great product for free ! Using it next to stayfocusd that I discovered first but this one has keyword matching that allows me to block certain type of youtube videos while still using youtube ! Awesome work.
  • (2021-03-10) Amelia Loucks: i hate DO NOT GET IT
  • (2021-03-08) CJ Cheng: Honestly, the best website blocker I've used. It requires a small bit of reading the FAQs to understand how to set up, but the customization options are unbeatable. Also it's free!
  • (2021-03-06) Harriet Ley: Fantastic. Much more sophisticated than previous blockers I've used. Timetabled blocks help to promote adherence
  • (2021-03-02) Skye Nygaard: Really works the best out of all the blockers
