Site blocker blocked all websites on the internet

Literally. I downloaded an add-on for Firefox called SiteBlocker and when I went to block a site it blocked all alone accessible Internet site (including the homepage and all search engines). So when I open it, just to give me a blank page and tells me that the site has been blocked. I tried to uninstall and reinstall the browser, but that did nothing. I had to use Microsoft Edge of this post. Also, I don't know how to remove the add-on because I can't even him.

You can start Firefox in Safe Mode where all extensions are disabled and remove it. At least, I hope that you can remove to it installed outside, you may have to use the control panel.

Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

and OK reboot.

Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

Then you should be able to access the Add-ons page and remove this thing.

To return to normal, exit Firefox and start it without hold the SHIFT key.

Success?

  • How can I allow one of my children to use local applications, while temporarily blocking his access to the Internet and while allowing children to continue to access the Internet?

    I have three children who have separate user accounts on our two computers. Both computers running Windows 7 Home Premium edition. We use Windows Live Family Safety on each computer to our parental controls for defining when and what each child can access. We used the period of parental control feature to block every child signed to computers, except when we allow. (It would be nice if we could block a computer and allow them to use the other.)

    However, I can't find a way to allow a child to not use the computer for local activities (for example, Microsoft Word), while blocking its access to the Internet. I also want to allow his brothers to continue to use the Internet during this time.

    Any help would be appreciated. Thank you.

    Hello

    Windows parental control have no option to directly block access to the internet in a Windows user account, because the system needs to provide activity reports. To work around the problem, you can block all internet browsers available for this user account so that the child have no way to access the internet. Restriction of the app to access the control that installed programs on the computer children.  Here are the detailed steps to block some apps:

    1. on any computer, log on to the parent account for http://fss.live.com

    2. click Edit settings under the name of the child you want to change the settings and then click the App restrictions.

    3. check the circle next to turn on the restrictions of the app.

    4. check all programs related to access to the internet or type the application in the area of Search apps .

    5. check the box next to the application or the program once it appears in the list.

    6. click on Save.

    This settings apply only to that specific user account. If you have any other questions, please let us know.

  • From Firefox blocks all access to the network

    When I start Firefox (41.0.1), all access to the network is completely blocked. Before you start the FF, I can access the Internet (with Chrome or IE), other computers, but as soon as I launch Firefox, all access to the network (including the connection to other computers) is blocked. In addition, my computer will turn off more.

    As far as I KNOW, I have not installed lately extensions or add-ins.

    Thank you for your resolution. Today, when I mentioned to work, I was told to update Firefox. This seems to do the trick (so far, fingers crossed!).

    (https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings) so very probably an extension is causing harm.

    When this isn't ' t the resolution, I will surely return to your resolutions.

  • Text blocks all appear in the tab order?

    It is a recent thing, I noticed. I have imported a Word document, and all non-fillable text blocks are appearing in the tab order. Is there a way to tell LS to include only the user interactive fields in the tab order?

    Curiously, when I preview the form, the tabs stop only in the fields, so it runs very well on the end of the user. It's mostly just a gene of design because when you configure the tabs, there are so many blocks of text that I have to work around.

    Screenshot below.

  • Problem connecting to some websites on the internet

    My son is in the training camp at Great Lakes, HE.  I keep trying to go online marine sites to get info and will not open.  For example www.bootcamp.navy.mil I could access these sites on different PC, so the problem must be just this PC.  If you could help me ill get this please.  Thank you, Patti

    When you try to open this error message you get (the EXACT wording, including all codes)?

    Try to add the sites you want to visit to the list of Trusted Sites.  In Internet Explorer, go to Tools / Internet Options / Security / Trusted Sites / then add the websites you want to add.  Make sure that the only use https check box is NOT checked.  It can substitute for what is blocking your access.  What security 3rd party software are you using as appropriate (program or firewall or AV security suite)?  It is possible that this software does not block the connections.  Because I don't know what it is, I don't know how to tell you how to solve this problem, but in general it is the same with IE - find the routine that controls access and grant these permissions to sites (or generally lower security level).  In IE, I use a custom security level, but the default is medium-high (new in Tools / Internet Options / Security / Internet Explorer).  You can reduce this mouse to the next level to see if it gives you go (or you can try to customize what is a better option, but a little more advanced).

    If this does not work, please transfer your question in Forum Internet Explorer: http://social.answers.microsoft.com/Forums/en-US/InternetExplorer/threads where people who specialize in issues of IE as you connect to the web sites will be more than happy to help you with your problem.  If please include responses to questions here and the following steps you have already taken to try to resolve the problem so that you will get the best service.  BTW, I could access the site that you posted on my laptop without a problem - then you're right on it probably not be a problem with the web site and have something to do with the configuration of this computer's security.  I have no idea why it would limit restrictions to the marine Web sites (unless your system is not sufficiently secure and sites won't let you because of that - but I'm not sure know how to fix this because it is the opposite of what I have already suggested to solve the problem).  You should ask the experts at the Forum of Internet Explorer.

    I hope this helps.

  • Firefox won't open all websites, just the white pages.

    As the title suggests, whenever I try to open a Web site in firefox all I get is a blank tab, so far I have reset firefox, update, reset again, restore my computer to an earlier date, lost all my favorites, them recovered through a backup, reboot again and even seen a place to delete the places.sqlite , so I did and restarted firefox. Basically nothing fixed firefox. I really need my firefox at work as it is used in a store to order parts and stuff and all the names of users for different sites are saved in firefox, without which I call around many parts stores to get my user names and password reset, so I can access the sites of chrome. I don't really want I like firefox. Any help at all?

  • Site Web Server not accessible via the internet

    Hello Apple community,

    I had a problem with the.app Web sites, where my site Internet (FQDN) is accessible via the network internal, but not accessible through the internet. I have port ports 80 and 443 passed on my firewall and I can see the ports open via nmap on an external connection.

    When I browse the site via http, I get redirect to 443 then it just resets and I get no error page. Internally, the page redirects to 443 and loads fine with the popup of trust initial cert (self-signed cert) that I then store to my keychain and loading the page well. I get no this pop up via an external network.

    Accessibility is accessible by 80 (green circle icon) but not of 443 for reasons I can't understand.

    I already tried to remedy the situation of the measures:

    Create a new self-signed cert to use. (same results)

    Disable ssl and disable redirection. (causes a load error in the browser)

    Wiped the OS reinstall OS X El Capitan and.app. (same results)

    Checked the port forwarding on my firewall Meraki 15 times (looks good)

    Disabled the feature IPS of the PPE on the Meraki (same results)

    Hello

    There are various reasons for internet connection doesn't work after installing the update of windows on the computer.

    First of all, I would say that you check the update is causing the problem.

    To see the updates are installed on your computer

     

    (a) open the updates installed by clicking the Start button, click Control Panel, clicking programs, and then r undeprograms and features, click view installed updates.

    Once you know the update's KB number then visit the Microsoft Download and put the number in the search box, download and install the update manually after placing the computer in a clean boot state.

    http://www.Microsoft.com/downloads/en/default.aspx

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

    eMachines PC Desktop ET1331G-05w with AMD Athlon II X 2 Dual-Core processor 250U & Windows 7 Home Premium

    Just bought this computer last week and everything works fine until the update of Windows 7. Now I can't connect to internet on my browser (Mozilla Firefox) or run other software that accesses the internet. I can ping and get an answer to www.yahoo.com. My computer says that it is connected.

    I'm running through a modem cable to a router. Another computer works through the router fine, so is not router problems or a cable.

    If I restore before the update, it works again. The problem is that it is forcing me to update again when I turned off the computer.
    I removed all virus protection software and it does not solve the problem. What is a firewall issue? Diagnostic software says it can't find a problem... I think he sees that I am connected.

  • URL filtering - allowing one single site, blocking all the others

    Hello.

    I want to use ASA to allow a computer to access a single website (www.tsf.pt).

    I used the following Setup, but I'm not be able to put it to work, since all web traffic is prohibited.

    access-list Inside_mpc line 1 extended permits object-group Web_Access virtual object TI any4 (Web_Access group allows http and https)

    Regex TSF "tsf\.pt."
         
    type of policy-card inspect http TSF
    parameters
    violation of Protocol action drop-connection
    not match request uri regex TSF
    Reset log

    TSF-filter-class of the class-map
    matches the access list Inside_mpc

    Policy-map filter TSF
    TSF-filter-class
    inspect the http TSF

    interface of TSF-filter service-policy inside

    My idea is that anything which did not correspond to the www.tsf.pt would be refused. After I failed to do so I configured the policy with an match request uri regex TSF (with delivery to zero and newspaper) and when I opened the site I have seen increasing political access number (it was just to check that the ASA dealt with regex).

    After I tried the following policy which does not also (did this because I didn't know if it was implicitly refuse at the end of the political map)

    type of policy-card inspect http TSF
    parameters
    violation of Protocol action drop-connection
    matches the query uri regex TSF
    Journal

     match not request uri regex TSF
    Reset log

    Is there something wrong with my config? Am I missing something?

    Thanks in advance,

    João.

    Hello, João,.

    Fix your regular expression:

    Regex TSF "\.tsf\.pt."

    You can test if your regex is correct by testing using cmd:

    ciscoasa (config) # test regex www.tsf.pt "\.tsf\.pt".

  • Updated Firefox updated to its latest version 12.0. Now my plugin Adobe Flash freezes and blocks all websites when it is turned on even if it's the latest version.

    Today updated Firefox updated to its latest version 12.0. Immediately after the update, I couldn't load most of the sites. The web browser would just freeze. I have determined that the culprit is the Adobe Flash Plugin, however; even with the latest version of the plugin, I always have problems. Any suggestions?

    If anyone else has this problem I found a few options that may help you.

    I solved my problem by loading Waterfox, which is the 64-bit version of Firefox. I use a Windows 64-bit operating system, so this solution worked perfectly. If you want to download it, it can be downloaded here: http://waterfoxproject.org/

    It has also been suggested that I try to create a new Firefox profile. Since Waterfox works for me, I have not tried yet; However, I was told that it allows to solve several mysterious questions of Firefox with Flash. The directions for this can be found here: https://support.mozilla.org/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile

    I hope everyone can solve their problems of Flash Player and I recommend using the Adobe Forums as well. People there are very helpful.

    Good luck!
