LeechBlock NG enables productivity enhancements via a suite of complex settings and options for blocking certain websites, making redirects, and helping you to manage your configurations.
How does it work and what is a block set?
This browser enhancer can turn out to be extremely useful for users who want to avoid productivity killers and keep the focus on the most important aspects of their work. However, for maintaining a certain workflow, you need to first understand your procrastination patterns, so you would know what to avoid.
The tool allows you to configure multiple block sets. Each one of these is a separate section where you can add different sets of websites (you can add up to 30 sets, for each procrastination pattern you identify in your behavior), configure unique rules for how and when these websites will be blocked, set up the site-blocking mechanisms, allow temporary overriding for certain addresses, apply filters onto websites' interfaces instead of blocking access, etc.
Main traits, wildcards, and the lockdown function
When using your PC for work, inevitably you can access, in a matter of seconds, different websites and addresses. That is why it would be useful to block the ones that waste your time. However, sometimes, when conducting research or having to access those sites for professional reasons, it can be a burden to start looking for the setups that block your access. The Firefox add-on will allow you to limit the access within certain periods, whitelist certain websites or specific addresses, or access a site for a limited time only.
On the contrary, if you are trying to make it even more difficult for yourself or others that use your PC to access certain sites, you can enable the 'Lockdown' function that immediately blocks the specified addresses for a predefined duration. Also, you can use the wildcard notation for blocking a wide range of websites (e.g. using *hm.com, you can block all the H&M websites, from all different countries, regardless of the differences they have in the URL).
Last but not least, if you plan on using this extension for parental control or even for yourself, to make it even more difficult to disable the website blocking features, the Firefox extension allows you to add a password to your LeechBlock NG menu.

LeechBlock NG is a simple productivity tool: a web browser extension 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.
LeechBlock is available for Mozilla Firefox, Google Chrome, Microsoft Edge, and other Chromium-based browsers such as Brave, Opera, and Vivaldi.
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).
The sites to block can be specified using wildcards (e.g., *.somesite.com) and exceptions (e.g., +allowme.somesite.com).

You can also set a password or random access code for LeechBlock’s options page, just to slow you down in moments of weakness!
Important note #1: LeechBlock is not designed for parental control or for blocking offensive content. You are advised not to try to use it for these purposes.
Important note #2: Although LeechBlock prevents you from browsing sites (at the specified times) it may still allow your browser to briefly connect to those sites (so that, e.g., your IP address may still be logged by the blocked site). If you want to prevent any such connection, you should use some lower-level blocking method (e.g., install and configure a HOSTS file manager like HostsMan).
