  • Cannot create a shortcut on the desktop for a Web site in the browser Firefox Tor

    I am a user of Tor Browser, and I love the interface of Firefox. According to my page, my Firefox browser is up-to-date. But for some reason I can't save shortcuts to office for a Web site. Whenever I drag the icon beside a Web site (variously a glob, a green bolt and other icons), I get a mouse icon of denial no matter where I try to put the web shortcut on the desktop. This happens even when I drag the bookmarks of my bookmark bar! My guess is that something is blocked in Tor allowing no shortcuts settings. Any suggestions on where the parameters of the shortcuts are in Firefox?

    Fred, all other modules worked well. I contacted the people of Tor, and they were unsure of what's going on. I've pasted their response below, but the short answer is that they have me just save shortcuts manually from the office whenever the Tor Button is active. Thanks for your help, you've been great!

  • Firefox keeps asking for password when I send emails

    Firefox version 35.0. When I open Firefox and do pass on messages, no problem. When I write an e-mail and send it, Firefox asks me password. I am able to send and receive e-mail while open. If I close Firefox and open, it ask password when I send. Months ago, I changed my password to connect to (which made more secure). Since then, I had this annoying password request. How to satisfy the password login server for receive/send emails?

    Is it asking for the password, or the web site of Firefox? The only time that
    FF you will be asked a password is if you have the active master password
    in the Password Manager.

    Open the Password Manager. There is a search bar on top of the
    page. Enter the name of the site. Press the button view passwords.
    What's the correct information? Note: maybe more then one entry there.

    Left on the icon in the address bar. A display of site information window should appear. Select more information. At the top of the window, select Security. Now select passwords saved view.

  • Why firefox did ask to make changes to my computer whenever I open the browser. Why is the screen pixelated all?

    When click on firefox on my desktop that a message appears to ask me if I will allow firefox to make changes to my computer. It happens every time. each page is also all pixelated and barely visible. the Explorer IS NOT to do THIS.

    A possible cause of this message, it is that Firefox is configured to run as administrator.

    Make sure that Firefox is not set to run as administrator.
    Right click on the desktop Firefox shortcut and choose "Properties".

    Make sure that all items are disabled in the tab "Compatibility" in the Properties window.

    • Privilege level: "Run this program as Administrator" should not be selected
    • "Run this program in compatibility mode for:" must not be selected

    Also check the firefox.exe program properties in the program Firefox (C:\Program Files\Mozilla Firefox\) folder.

  • Firefox displays only numbers and no text in some web sites. whereas the Internet shows explore them all to the same web site. What is the solution?

    When I click on a link in a web site, it is supposed to show the details on another page of the same website with text and numbers. But it only shows numbers. Why?

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do not click on the reset button on the start safe mode window or make changes.

    Alternatively, you can try to start the computer in safe mode Windows with network support (on the startup screen, press F8) as a test to see if it helps in the case where your security (firewall, antivirus) software causes this problem.

  • Firefox keeps asking for an update, but is unable to complete. It is stuck on the "Connecting to Server" and turns for hours until I stop. Help!

    I have a version of Mac OS X 10.5.8 and I used Firefox on it since I got it 3 years (?). The most recent update for Firefox and Thunderbird guard invites me, but when I say 'yes' to update, a bar with lines moving through it, and he said: "Connecting to the update server", but it is never a more far. I left for hours at a time and it does actually update or another program.

    If you have problems with the update then more simple is to download the full version and trash the version currently installed to do a clean install of the new version.

    Download a new copy of the Firefox program and save the file on the desktop DMG

    • Trash the present application Firefox to do a clean (re-) install
    • Install the new version you downloaded

    Your profile data is stored in the Firefox profile folder, so you will not lose your bookmarks and other personal data.

  • Cannot download files because Firefox keeps asking for consent and there is not a button ALLOW anywhere

    Firefox needs your consent to download large files.
    Please, click ALLOW to continue with your transfer.

    If you do not see the application, please click on the icon next to the address bar.

    I didn't have this kind of problems before up to that new version, I'm so frustrated that I think really switch to Chrome instead.

    And in case anyone is wondering, there isn't an icon request at ALL.

  • Validity of the certificate of security on a Web site

    I am looking for help on the validity and security of a Web site.
    The page in question is the one that opens when you click the 'Start' button on this page:

    When you press the "Start now" button a new tab opens and briefly a green padlock is seen before turning into a gray triangle with an exclamation point.

    My questions are:
    Is the site secure?
    And if that's why I make the gray triangle with the exclamation point?

    Thank you very much

    You can use the Web Console to examine more closely the problem. Here's how:

    Open the Web Console in the lower part of this tab using Ctrl + Shift + k or the menu Developer.

    Reload the page without going through the cache (Ctrl + Shift + r, or shift + click the button reload of the address bar).

    Look for the red triangles.

    As stated in the joint, the site hosting the analytical script uses the algorithm of RC4 encryption, including 36 of Firefox and later treat as unsecure. In a future version, Firefox even will not load the script, so it's something that the site should try to develop with its supplier.

    McAfee is a huge problem with Windows Mail.  See if you want to use, wait until you get the job of Winmail.

    Check if you can connect webmail and that works very well and it's not a problem on the end of the server messaging or because of misspelled powers.  Then delete your account in WinMail, compact and repair the database (see and make sure that you have disabled the e-mail analysis then add your account to mail back again and see if it works.
