Works fine, worth installing

fast, easy, perfect Rated 5 out of 5 stars

all you need to do what's promised. block sites!

Rated 1 out of 5 stars

Unfortunately, the white list doesn't work at all. It allows to open any website when it's in the white list mode.

Free warning messages will be better. Rated 4 out of 5 stars

I hope user can edit warning messages, because current warning messages are too straightforward.

Junk. It only works occasionally. Sometimes I can type a blocked URL verbatim into the URL bar and Firefox gleefully goes there. I wanted to use this to elide tracking sites that tend to be embedded in every web site on earth, but I can't be confident it will block them.

RECOMMENDED for fast blocking! -and continue your browsing. Rated 5 out of 5 stars

no registration needed (- like other block-software)
fast to use .
it does not lead to wips - like some degenerate person here was yelling.

-with this you're back browsing in minute

This was promising but failed a lot. I couldn't access a website where I do my work. Until fixed, this is crap and only making problems for your computer. DO NOT INSTALL IT. It needs to be fixed!

Я не понял это говно блокирует сайты? Тут не знаешь, как на сайты попасть.

SPYWARE ALERT DO NOT DOWNLOAD Rated 1 out of 5 stars

Total BS, hadnt added anything to my addons in 6months, then after updating FF, this thing shows up with its WIPS page every time i load the browser, then adds insult by blocking pages if you decline to participate. SPYWARE ALERT. do not download and check registry to make sure it isnt STILL accessing your info after uninstalling

Used to work, but now:
- Block almost every site, even if the blacklist is empty
- Is loaded with the WIPS.com crap, which will spy on you while you are browsing

Used to work, but now it doesn't

Not good. Rated 1 out of 5 stars

I used to have this on my Mac (now I have Windows) and it worked perfectly fine but that was 3 months ago.
Now it doesn't work at all.
I imported a bunch of phishing and harmful websites from my old computer but it still lets me go on them. (I tested it out with one *less* harmful site).
I do not recommend it just because it doesn't work at all.

Rated 1 out of 5 stars

I installed this way back, had to regulate a user surfing infectious sites, so necessary and non-imposing to begin. This was some years ago. I blacklisted various sites that long ago as well, and did not tinkle with the extension in the least since then.
The naughty site-seeking user is long gone, and the extension is (WAS) still on. I suppose I should have removed it, but now I am glad to have removed it via this review threads tips & feedback (thanks for about:config settings!).
To the point:
Beginning one day prior to penning this review and extension removal my browser began acting like a useless gob-of-pointlessness, I ran through a trouble-shooting this and that, everything was fine; except it wasn't, the PF Usage was spiking, and I had to end FF multiple times and come back inside FF in safe mode to suss abouts.
Then in checking add-ons, etc, I said I wonder if it's this blocksite deal, and yes, I do not need it anymore, let's see. Done and Done, problem solved.
Now the machine is running so smooth, it's like a new item, I had been hearing grumbling and hard-drive noises (?) for weeks, flippin' data-miners/spy-nuts.
Avoid this extension!!!!!!!!!!!!!

Spyware Rated 1 out of 5 stars

This add-on was great and I loved to use it.

Then this company take a diarrhea dump in the source code for money....


Rated 1 out of 5 stars


I could no longer access www.thepiratebay.se through Firefox while this was installed because it redirect to a static 'blocking' page run by Datavalet Content Control Services


DO NOT install this extension before carefully reading their non-privacy "privacy" policy

more wips.com extensions to look out for...

Permanent blocking Rated 1 out of 5 stars

Block Site worked during three days. Then, all the blacklisted sites disappeared from the list and Block Site blocked every and all sites. Seems unreliable.

Blocks everything Rated 1 out of 5 stars

I added one site to the blacklist and then it blocked every single link I clicked on!! I will find something else, this add-on is garbage.
