I have blocked all the Web pages of my University by accident.

Thanks for your help. I was on the site of Blackboard at my University (I'm an instructor) and was trying to listen to the podcast of student assignments. An icon like a lego brick appeared with the message 'a plugin is required to play this content. At the top of the icon is a little link that says "block X".

I clicked on this link, assuming that he would allow me to 'unlock' the material. In this window of Firefox I asked for any material domain name www.nd.edu.au at my University to be unlocked, but now I've lost all access to all of its pages. Looks like I have everything blocked by mistake.

I searched all add-ons, but cannot work out what tool is being accessed down. I don't have a lot of plugins. Those who are activated are: Addobe AAM detect; Help browser by default; Flip4Mac Windows Media plugin. Java applet; SharePoint browser plug-in; Shockwave Flash. and Silverlight.

It does not resemble a parental control setting Mac, I can navigate to these pages in Safari. In addition, starting Firefox in safe mode returns all access.

I looked online for answers also.

I would be grateful for any help.

If you use extensions (Firefox/tools > Modules > Extensions) which can block content (e.g., Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that these extensions are not blocking content.

If it works in Mode safe mode and normal mode with all extensions (Firefox/tools > Modules > Extensions) off and then try to find which extension is the cause by allowing an extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit ' (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit)

You can control and manage permissions for all areas on the Subject: authorizations page.

  • Go to the permissions tab (Tools > Page Info > permissions) to check the permissions for the domain in the currently selected tab

Delete the permissions.sqlite file to reset all the permissions.

  • Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox window is sometimes "off screen" somehow. Often, you can force it to appear on the screen by right clicking on the thumbnail image just above the taskbar and choose expand. Does it work?

    A possible cause for this is that the file that stores the positions and sizes of window is corrupt. You can delete this file and Firefox will return to standard window resizing.

    #1 method: If you can get a zoomed window:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    Pause while Firefox finishing its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    #2 method: If you can not get a Firefox window for all:

    Close Firefox by right clicking the icon in the taskbar > close all windows.

    Using the Run dialog box (windows key + R) or the start search bar menu type or paste the following and press Enter to drill down to the profiles folder:

    %APPDATA%\Mozilla\Firefox\Profiles
    

    Here you can see a folder - in this case, double-click that - or more than one case - in this case, double-click on in what looks like the most recently updated.

    Scroll down and rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    Then, to re - light bars, you can use one of the following methods to view the list of the toolbar, and then select the desired bars it:

    To activate the menu bar, toolbar bookmarks or other bars, click it in the list.

  • Is there a option of zoon of the Web pages with Mozilla Firefox, if I have trouble reading the small print?

    I take a class any web business, and I can't find a lot of the functions that they speak.

    Hello
    Have you tried the Firefox zoom feature? This initiative will increase the size of the web pages.

    • To make things bigger, press Ctrl and + at the same time.
    • To make things smaller, press Ctrl and - at the same time.
    • Pour reinitialiser to reset the size of return to normal, press Ctrl and 0 at the same time.

    You can also use the NoSquint add-on to change the zoom level by default for all websites at the same time. After setting your overall zoom level, you can still adjust the zoom on different sites.

    With the help of NoSquint:

    1. After installation of NoSquint, make sure you have the add-on bar displayed:

      • Click the new tab button ("+") or a box empty bar tab to the right of the item and choose the module bar on the shortcut menu.
    2. Click on the % in the bar of the add-on call site preferences, then click the global settings button, then the zoom tab.
      • You can experiment with sizes greater than 125%, but it is not recommended that you will more than 150%, unless you have a large screen high resolution.

    If there are sites that are still a concern, feel free to post their URLs.

    Please let us know if this helped you!

  • Update of Firefox, and now all of the web pages and icons are inflated. How do I put back it as it was?

    Update of Firefox, and now all of the web pages and icons are inflated. How do I put back it as it was?

    Hello

    Firefox on Windows is now after display, scaling options that can make the biggest text on screens at high resolution.
    You can adjust the resolution of your screen.
    To change it follow these steps:

    • Type of topic: config in the Firefox address bar and hit the Enter key.
    • If the warning that this might void your warranty , click I'll be careful, I promised.
    • Search for layout.css.devPixelsPerPx

    • Double-click layout.css.devPixelsPerPx to edit its value. The default value is - 1.0 in Firefox 22 and above. Change it to 1.0 to run as in previous versions of Firefox.

    If necessary, further adjust the value of 0.1 or 0.05. Values between 1.0 and around 0.5 to reduce the size of the elements. Use a value greater than 1.0 to increase the size. For example, a value of 1.25 will increase the font size of the 125% to account for the default DPI setting in Windows 8. Check the value that you enter. Definition of a value that is too small will take everything away and too high will explode things.

    If the web pages should always be adjusted so you can watch the extension Default FullZoom Level or NoSquint .

    To adjust the font size for the user interface, you can use the extension of theme font & size changer .

    This solve your problems? Please report to us!

    Thank you.

    I see that you get a secure page and that you are unable to print black on your HP Photosmart 5520 e-all-in-one printer. I'd be happy to help you with this.

    I like that you get the login screen for the Built-in Web server for the printer. Is this correct? This seems to indicate that someone has put a username and password on the printer, for security reasons. If you don't know what are the connection information, the only way to remove this is to do a factory reset on the device. I can send you this information in a private message. In the forum next to your handle name simply click on the envelope to see.

    That being said, I would like to start here. Please, try the steps in this guide, the printer prints blank Page or fact not printing black or color ink for HP Photosmart 5520 and Deskjet Ink Advantage 5520 series e-all-in-one printer.

    If you have completed all the above steps and your product still has a problem, the printer service.

    First, check your product warranty to check your warranty printer status and then go to contact HP support to find an authorized dealer or to schedule a repair.

    Why is the size of the Web page to get more small or bigger while I'm online? Am I touch a button or by pressing something by accident? This happens to my daughter. We have all two computers laptops sony vaio. Does anyone else have this problem? Is there a way to avoid this?

    It is possible that one of the CTRL on your keyboard is blocked by sticky dirt coke or a faulty design on this model since it happens on 2 different Laptops:
    If you use the mouse wheel to scroll up and down your pages in Internet Explorer, CTRL + roulette is a shortcut for zoom, what would cause this symptom.

    The Vaio seems to use a complex configuration of the main keyboard drivers, search the Web for "sony vaio ctrl key pressed" to see some of these horror stories and how others solved the problem. Add your specific Vaio model name to the search string for more accurate results.
    Also check if the function FN keys work correctly, go to the Sony web site to check the driver for your model and Windows 7 updates.

    If you need to clean the keyboard, I suggest that you seek professional help.

  • Firefox keeps blocking all the links, I click to open in a new window even sites that are on my allow list and secure government sites. How can I stop?

    Firefox blocks everything I need to click on allow and on some sites I do several times that the Web page reloads the page for a new investigation.
    Very annoying... enough so that I can stop using firefox and not recommend it to others.

    Firefox normally a redirection to another address will automatically follow.

    You can check that the block of redirection is not lit? This setting is on the Panel of the preferences page:

    "3-bar" menu button (or Firefox) > Preferences > advanced

    Under the mini general tab in the accessibility section, uncheck the box "warn me when websites try to redirect or reload the page.

    If you have changed that, no matter what difference?

    If it was already off, it could be an add-on, or some security software or another program filtering that changes an automatic this intermediate page redirect.
