  • Did exactly what it said it would.

    HOWEVER, will there be an update for Quantum?

  • Been using it for several years now and still working good. KYL Please update it to work with Firefox 57 (Web-extensions) would be a shame for this great addon to stop working in Firefox 57. Overall great job!

  • Have been adding hundreds of crap urls to my list and suddenly is´s all gone.

  • ... But, now, it's not working any more. Like all other site blocking add-ons, this stopped working (well, at least, it worked the first time I ran it, others usually fail from the start). Why is that no add-on seems able to block sites on Firefox?

  • Hey dev (KYL)! Can you seperate whitelist and blacklist pretty please?

  • does what it says it does.
    don't expect too many features though.
    I got used to it and I'm happy with it.
    Big thanks to the developer! It helped me out a lot.

  • Very easy to use and blocks whatever you need without any problems. Thanks for this awesome app and hope you keep it updated in the future.

  • The add-on is great but in blacklist or whitelist just work for specific websites not for domains, for example i want block youtube.com that work but if access to a subdirection like youtube.com/watch?0988svs8 doesnt block.

    Well, i can wait that you add support for Domains
    Regards

  • It worked as expected, except for the fact that I could not add a password, in order to block the access to the configuration. Pushing the accept botton did not work. And, of course, it would be nice, if possible, to use the password to grant access to disable or eliminate the app.

  • Simple and efficient. Can select what I block and it always works.

  • user-friendly: 3/5
    ✓built in gui
    ✓simple terminology
    ✓easy to learn
    ❎easy setup:
    This addon is very tedious when it comes to setting it up to block a site.
    -pull up the add-ons page
    -select the "options" button,
    -clicking "add"
    -enter the full domain name
    repeat to setup the add-on's list (no helpful prebuilt lists)
    >subcategories: (features of an easy setup addon)
    ❎>toolbar button/menu (good example: ad block plus)
    ❎>context menu option (right click menu option for quick access)
    ❎>shortcut combo(such as alt+F4 which closes almost any active program window)
    ❎>autocomplete (though it has a feature where whatever is in your clipboard at that time can be added to the list quickly; this is still a problem if: A| You did not copy the url before entering options, B|The snippet url does not include "http://")

    ❎advanced features
    features that an add-on like this should contain:
    >documentation of how to create, edit, and format, importable lists.
    >wildcards
    >keywords

    creating, editing, formatting, and importing lists.

    application to use: notepad
    file extension: txt
    add-on required save location: none (can be saved anywhere, as long as the file is accessible)
    file name syntax: none (as long as the file is a txt file, it can be saved with any title you wish)
    list formatting (lines with an "*" are required and must be typed exactly as what is typed after the "|" ) (lines with "#" are formatting templates aka syntax. "{ }" are to be replaced by the website you are blocking.)(a line marked with "^" means repeat line above as much as needed):
    *Line1| [BlockSite]
    #Line2|http://{insert.domain.here}
    (ex: http://www.bing.com)
    ^Line3|

    Importing
    after finding the txt file, a text box appears asking if you want to append or replace the existing entries.

    if importing a new list with no previous entries: select replace

    if importing a new list to an existing list of entries( no duplicate urls): select append

    if importing an edited (exported) list to the original (unedited) list: select replace

    if using 2 different lists, export the combination and edit the entries this way or else you will have to append the edited file and erase the original entries one at a time.

  • Its usefully for blocking formerly good site gone bad (like domain sold to adware).

  • Very good addon but as someone said before it needs a right-click menu integration or at least a button in the tool bar for quick access. If you add this then it's the perfect addon.

  • I must disagree with "John Doe"'s assessment that it has "no unwanted features". It has one that I know of without having to use the addon: It mysteriously appeared on my Firefox browser today when I opened it. Instead of opening my home page, I was greeted to a page congratulating me for installing BlockSite Plus--but I did NOT install it. Hell, it wasn't even installed on my browser the last time I used it. Now, without my knowledge or consent, BlockSite Plus has installed itself and interrupted my schedule. I don't know what happened to cause the addon or the developer to think that I wanted or needed BlockSite Plus on my machine, but it doesn't excuse your arrogance and blatant disregard for my privacy and my right to choose and make my own decisions. It may be a great program for all I know; but I will never know, because you violated my privacy, and I will not have it! Rather that try it and see what a good addition it may be to Firefox, I am uninstalling it and warning others about the unethical way it was installed on my machine.

    One question: Of all the people who use Firefox, why choose my browser to hack and my privacy to violate; or are you targeting ALL Firefox users?

    Oh, and one more question in closing: Does Mozilla know that you use such unethical tactics to peddle your wares?

    Developer response

    To SENAAHQ,
    Are you sure that you are referring to this addon or the addon named "BlockSite"

    https://addons.mozilla.org/en-US/firefox/addon/blocksite/

    For a bit more information, that addon was sold by it's original developers to someone that has turned it into some sort of spyware. This addon is not "BlockSite" nor does it have those spyware features.

    Hope this helps

  • Works great, but wish there was a button on toolbar for quick access.

  • No unwanted features, very light.

  • Thanks to have corrected the initial draft. It really miss an icon in the statut bar to finish the work correctly now ;)

  • It's better than BlockSite.

  • Not very useful since requires manually adding the site to block.

  • Hi there , the extension for my firefox , are awesome , the unique thing i need this do

    its prevent's open tabs or windows , with the site in the blacklist.

    The rest , the plugin works perfect for me :D

  • I tried 4 addons to limit access to time stealing websites. None of them worked better than this one. Some were fancier, some had more functions, some didn't work. This one does work and is easy to control. It gives me a blank screen where there used to be a website.
    Update: I'm using Comodo Firewall content filter now to block websites..

  • Works fine in FF 29.0.1.

    Please add right-click capability or icon! Too complicated for fast work.

  • sadly this add-on does not work

  • sinnlos

  • BlockSite Plus is fine for someone who wants to block sites and url-specific ads and images *for themselves*. The password feature is a bit silly, but the complainers here overlook the fact that securing your computer from people who have direct access to it is neither promised or implied by the write up blurb.

    There are a ton of different approaches and products that advertise controlling children's access to the internet, and this is NOT one of them.Among other things, I'm using it to block some annoying images (e.g.; yahoo added a useless background image to their calendar that makes it hard to read). Firefox's image-blocking will not let you get any more specific than blocking an entire site's images, while this ad-on can bock a specific url or portion of a url.

    It's biggest fault, as others have mentioned, is that you apparently have to go all the way into the ad-on menu to get to preferences. It really needs options for a toolbar button and right-click context menu. They might as well remove the password feature while they're at it, it is misleading.
