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).

  • (2022-06-29) Alex Landes: makes me reduce time on reddit, easy to setup
  • (2022-06-25) Ludwig Wittgenstein: This app is a gem. Honestly it's probably closer to a 4 stars for me personally because it still doesn't really stop me from going on YouTube or Reddit as it's super easy to disable. But the fact that it's free and at least makes me a BIT more mindful is a win.
  • (2022-06-22) tertpo tertpo: Simply, the best blocker on the market. No need to spend money on other extensions for blocking websites. You can direct to a useful website instead of just blocking them which is more effective.
  • (2022-06-21) lee shi han: not much to say except this is THE site blocker. It's comprehensive, it's detailed, and its free! That said the only issue with it is that its not too user friendly and would take some time to figure things out
  • (2022-06-19) Rock LuNex: Multiple Block Sets for different sets of websites as well as controling the time period for a single website for different days in a week?! Heck yeah!
  • (2022-06-16) Le raton laveur BG: Works perfectly !
  • (2022-06-15) Inky Dynk: I love this extension. Huge productivity driver. No-nonsense and just works. Love how easy it is to add sites to Block Sets and set times the blocks are active.
  • (2022-06-14) P T: No doubt the extension for regulation of internet consumption. Made out of pure kindness, with no ads, fees or upraged version, this is what you want. This extension has more customization option than any other tool, and most likely allow you to have the perfect tool against internet addiction! Huge thanks to the maker, for his excellent extension and for his kindness.
  • (2022-06-14) ANUSHILAN DAHAL: Would like a feature that allows only the selected sites and blocks everything else
  • (2022-06-10) Utkarsh Agarwal: Has everything you need for an adblocking extenstion..for free and no ads.. Wouldn't mind the ads but the best free stuff out there...Don't understand how freedom.io and blocksite still have there businesses running
  • (2022-06-08) Dean de Jager: Works very well. Thank you
  • (2022-06-07) Michael Amoruso: This is a great extension for blocking sites. I'd previously used BlockSite, but they handicapped its functionality (by limiting the number of sites you can block) to try to get you to pay for a subscription. That extension also made it too easy to unblock sites. LeechBlock lets you block as many sites as you want, has more functionality (block groups, time-delimited blocks), and is FREE. Great work!
  • (2022-06-07) SUHAIL KC: great work
  • (2022-06-04) boss little: 对于自制力不好的人,真有用。
  • (2022-05-23) Katarzyna Nęcka: Perfect, the amount of customization option is just fantastic
  • (2022-05-23) nylt: the extension helps me a lot to be more focused on my studies
  • (2022-05-22) Daniel Pekar: Hardly an overstatement to say that this product has improved my life. Packed with helpful features - love the customizability, and no paywall. Simply a no brainer.
  • (2022-05-13) Jacob Antonetz: Saves so much time
  • (2022-05-02) kk: LeechBlock is the best of the blocking site tools.
  • (2022-04-28) Rafaela Atoche Silva: it changed my life. tysm.
  • (2022-04-27) Garik Tate: The settings take some time to get used to. But nothing is better on the market to customize your blocking experience.
  • (2022-04-19) Dariuš Steckevič: Writing it before testing. But even now in first day of using that app i can say that, if you can setting it down, then you will easally control you productive time. If something will go wrong, I will rewrite a review.
  • (2022-04-19) Nathan Jacob: Love it. works perfectly. It's the only one that works for free 100% of the time with no ads
  • (2022-04-18) Adam Huang: completely adfree and very easy to interact with. allowed me to stay productive by redirecting sites that were distracting to me like tiktok and instagram. this definitely saved me while studying for exams and tests
  • (2022-04-15) Hitesh Trivedi: As they promise , best way to save yr time on unwanted site. i m using this from last 1 week and it save a lot of time of me on facebook and other site. Thanks a lot.
  • (2022-04-05) Heloisa Coli: A extensão é ótima, realmente ajuda com a produtividade e ainda é gratuita. Recomendo!
  • (2022-03-28) Akash Janapati: So effective and helped me to avoid social media. Thanks a lot for the team for providing this
  • (2022-03-26) Jeffrey Horwitz: Simple and easily customizable. Great extension!
  • (2022-03-24) Peeyush Jaiswal: I cannot thank enough for how much LeechBlock has helped me. It has saved my life actually. Even the paid blockers lack in one feature or other but LeechBlock has everything in it, and that too for free. The only problem was that the extension can be disabled or removed easily. But this problem can be easily solved by ForceInstalling the extension in regedit and then password protecting the regedit. After this little bit of extra work, this extension becomes the most powerful blocker I have ever come across (and I have done a lot of research).
  • (2022-03-21) Valentina Vergara: Muy necesario. Flexible para ajustar el criterio para bloquear las páginas (por horarios o tiempo máximo de uso).
  • (2022-03-17) James Garcia: Ajuda muito, por mais bobo que possa parecer apenas bloquear a página em 1 navegador, ajuda muito a melhorar a concentração, mas você tem que tomar cuidado pra não ficar burlando o sistema de "ativa e desativa" que ele possui, se não, não adiantará!
  • (2022-03-13) bc wong: very helpful!
  • (2022-03-10) 保下田久六: ブラウザ拡張機能なので簡単に無効化・削除できてしまう以外は欠点らしい欠点が見当たらない、非常に高機能なブロッカー。本当に無料でいいのだろうか。こちらのブログで使い方を日本語で解説している。 https://hadonishi.com/leechblockng-howto-basic-in-japanese
  • (2022-03-10) Ricardo Arastey: Es una herramienta fundamental en estos tiempos de procrastinación y de constantes reclamos para pasar cada vez más tiempo en cosas que no merecen la pena. Totalmente configurable, puedes modificar y personalizar cualquier aspecto de tu limitación de acceso a determinadas webs.
  • (2022-03-04) Mohamed Saher: Everything you may need for a disciplining yourself into productivity, wealth of options and for free amazing work
  • (2022-03-03) Kanishk Kumar: THE best extension for the needs of a student who has ADHD or just gets easily distracted & because of that their studies suffer. EASY TO SETUP & VERY EFFICIENT. !!AND ITS COMPLETELY FREE.!!
  • (2022-03-01) Taske: It works great, now I can finally take a break from the sensationalist news about the corona and the wars, now I'm finally not scared anymore. Block the news and enjoy life, you only have one. Thanks.
  • (2022-02-28) Liliana Kahn: It worked great on my old Chromebook. On my new Chromebook it makes Spotify stop after about 15 minutes if Leechblock is running. Not sure what changed, but something did. Aside form the glitch it generally works great and I usually love it.
  • (2022-02-25) Regis Lux: Better than any blocker I have ever used and trust me when I say I have tried basically everything in the market. Tons of customization, exactly what I needed! The only thing missing (maybe because I didn't figure out) is a way to block a site but keep some specific areas of the site that are actually productive, for example: Blocking the whole reddit, but keeping some subs that are helpful,
  • (2022-02-20) Alius Ali: The extension is failing on Vivaldi, it usually doesn't have access to the content of all the sites :(
  • (2022-02-16) Karan Kumar: This is the best extension for productivity. Plz give it a try if you want to get the best from your life.
  • (2022-02-14) Carolina Tutillo: Es justo lo que buscaba, algo que encontraba en aplicaciones para móviles, pero para ordenador no. Puedes poner varios bloqueadores con horas y días diferentes.
  • (2022-02-11) Le Thanh Quang: really helpful and productive and its free unlike other apps. I dont have money for donation but i really recommend using this
  • (2022-02-10) Paul Brick: I've been looking for an extension that could do everything LeechBlock can do...finally! Life-changing! Thanks to the team that made it!
  • (2022-02-08) müll eimer: Great extension, has all the functionality I need and it actually works very well, unlike some other (paid) alternatives I've tried before. Plus its open source, which is always a great thing. Big thumbs up to the developers!
  • (2022-02-07) Evan Oley: Fantastic. Of all blockers/time helpers I've had, this is the most intuitive, and helpful!! Thank you!!!
  • (2022-02-06) Arnav Aggarwal: superb plugin that improves productivity
  • (2022-01-17) Joe Chesterman-March: The best blocker ever and you can trust it's not tracking your data. Thank you so much James
  • (2022-01-17) Emily Faubert: Ad-free, effective, easy to use: this is the perfect browser extension!
