Firefox won't let me add some addons

I am trying to add some addons and it wont let me add any of them it keeps telling me that they are corrupt please help me with this problem

Hi mellyorajackson1967,

first of all check them that your selected addons are not on this list: https://addons.mozilla.org/en-US/firefox/blocked/
If in the list, then Firefox will block the installation and displays an appropriate message. If this is the case, you should check to see if there is an updated version of the add-on you were trying to install.

You can find more information here: Add-ons that cause security problems or stability are put on a block list

    I tried to uninstall and install not only the toolbar Yahoo, but Firefox itself. I also ran registry CCleaner it AM. I can add Firefox icons for Web sites, but not my own. I can only delete the icons by clicking right on it in the toolbar. I am frustrated because Firefox has always worked so well before with older programs. I am addicted to Firefox, so please help me to solve this problem. I'm not a technology person. I see you listed my plug-ins below; do you see a problem with them? Should I have my plug-ins "always turned on" or "ask to activate? Thanks for any help you can give me.

    need the toolbar? Why not use the building in search engines? Note:

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    You have also two versions of Shockwave Flash - groin should be deleted.

    This can be useful - disable or remove modules.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Firefox won't let me download and install Badger of privacy

    I want to download and install the Badger of privacy

    But I get "Firefox prevented eff.org asking you to install the software."
    When I click on ALLOW, I get
    "The Add - it could not be downloaded due to a failure of connection on www.eff.org".

    Badger of privacy does not appear on the list of Firefox Add ons

    The issue with the eff site or your service provider.
    It is not likely to be Firefox problem. I am able to load at the bottom of the file.
    I assume it's just the site you have a problem with eff.

    Install at your own risk.
