Much more simplier UI, than other blockers. Really nice, helpful.

used to work some (long) time ago, now it doesn't

Works perfectly, simple and easy to use. The only downside being that when you have for example, 10 tabs with different YouTube URLs and then you want to block YouTube, all the tabs lose their url and become YouTube, which means that after unblocking YouTube, all my saved tabs become the default main page.

DON`T USE THIS PLUGIN EVER! I had to report it.
When you have websites blocked, this plugin ruins all those tabs you have opened. it does not only forbid access temporarly, it corrupts the entire tab so it will never be accesivble again!

Also, the Ad-On is very unintuitive. but the main problem is that it will destroy your tabs.

Mozilla Firefox should not allow such a plugin.

Almost impossible to use and block sites

好用

The extension works great! took a bit to get used to but after messing around, I was able to get the customize the rules to my need. One thing I would like is a way to block some sites all the time and some on a schedule.

i thought this add on would just block me from accessing a website but instead it ruined all of my previously open tabs in a catasthropic way by changing the url. it just nukes your archived tabs, DON'T USE.

I lost my time trying everything to make it work, but impossible to start the blocking.

Works just fine for me. Simple and effective, and the "close" option is great. Leaves me staring at my desktop, wondering why I tried to open reddit for the 50th time this hour.

simplistic design. Easy to block and unblock sites.

it does its job, and does it well enough. i've been using it for over 6 months now.
