I can't thank you enough. I have installed old version of firefox just to use leechbock.

This ad-on saves my life! it is highly customizable, and can surely support your needs. I love you LeechBlock devs :)))))

Works as intended, but ended up disabling it when I discovered it is the reason that Firefox is never idling. So I have many tabs, and this plugin is always keeping 10% of the CPU busy (2 processes at 5% each). Disabling the plugin makes the problem go away. My version is 1.0.7.

The workaround mentioned in the FAQ did not work: count only active tabs setting did not make a difference for me.

The reason mentioned in the FAQ for this behaviour is:

> LeechBlock reviews all open tabs every second, to keep track of how much time is spent on the sites listed in your block sets and to determine whether any sites should now be blocked.

I do not need this "feature", I just want to disable access to certain websites from 9 to 5. Since I can't disable the feature, I had to disable the addon and search for a simple one.

Doesn't work at all for me. This is the second website blocking extension that didn't work.

Please introduce an on/off button with a timer.

Just when you thought there was no paradox in leech blocking to be found, Prof. James Anderson displays a thorough "analysis of its character, presence, and epistemic status" for the interwebs! Well done...

It works almost perfectly. I hate it. Uuuuuugh, guess I'll go back to work. Anyway, it's 4 instead of 5, because the temporary unblocking feature doesn't seem to work. The icon is yellow and everything, but the websites aren't unblocked.
Edit: see developer response, it was user error.

Bescherm je zelf tegen afleidende websites zoals zogenaamde "sociale media" en nieuwsmedia.

Set a timeout and block sites for a duration, then refresh the time limit. Plus tons of customization for every combination of limit - limit during a set time of day, or set limits /except/ during a set time of day. There are even thoughtful and creative options for making websites unpleasant to use to wean off of bad habits without going fully blocked. Everything I could ask for plus gave me some new ideas for how to manage my time and break my bad habits. I'm fully impressed.

Very good blocker. Exceeds expectations.

Designed quite well I'd say
