Does not work at all.

Does not work for the websites I configured

Does only work sometimes and is unconvinient to use

Great extension! Idk how some people can just say "it does not work".

This extension does in fact block websites, and the orange banner that appears on blocked websites is a nice touch. However, it is sometimes difficult and counterintuitive to black specific websites. You have to be really particular in order to get a website blocked. I have had some instances in which I was easily able to block a website. I simply typed in the URL and that was it. Other times, however, it took many attempts to get a certain website blocked with this extension, and critically, I do not know what I did when I was successful that was different from what I did when I was unsuccessful. Nevertheless, I appreciate the developer's offering of a website blocker extension.

Doesn't work

If I can't even block one website, www.youtube.com, what does this extension do other than scrape my browsing data?

This works great! I can block distracting websites like YouTube.

Simple, realitively easy to use once you figure out to use the "Block domain and all subdomain" setting. Works really well to block unwanted websites. Only thing holding me back from putting 5 stars is that it would be nice to have a password lock option to prevent unwanted changes to the block list.

i can block reddit

Doesn't work for some reason, tried blocking youtube.com, facebook.com and reddit.com.

Edit:
I figured it out, when using the default rule (Block domain) it only applies to the second-level domain (youtube.com) but since many websites redirect to www (www.youtube.com) it stops working. Using the rule "Block domain & all subdomains" fixes this problem.

Tried to block youtube and twitch, it worked. However, when I tried blocking instagram, it doesn't. Dunno why...

Very much good, I easy block fakebook.com

Easy enough to use, added the websites I wanted to block, set to block in private tabs etc, closed Firefox, restarted, entered one blocked website address, it loaded fine, entered 2nd, it loaded fine, tried 3rd, same scenario, it just isn't blocking these websites.

I watch too much porn

Nice and simple, works great!
