Firefox does not recognize that I already have add-ons installed (prompts to install add-ons I already have installed AND turned on). Why?

Add-ons, which are updated and already installed and running (and have been for some time), seem to think they are not added. When looking at my add-ons in the Tools menu, they are listed as enabled. However, clicking to go to their information page on the web (where you can read reviews, and where you originally chose to add them to Firefox), the "add to firefox" button is available. (As opposed to some sort of "already installed" or "uninstall" or "reinstall" button) I tested the button to see if pressing it would THEN tell me "you already have this", but it didn't! It started downloading the plug-in I already have! What is going on?

hello Amsuko, the "+ Add to Firefox" button on addons.mozilla.org and similar sites is just a normal static element on the website. websites don't have the possibility to query which extensions a user has already installed (this would probably be seen as a privacy/security breach). in case you install an addon that is already present on your system, it will simply get replaced...

  • I cannot access my linkedin profile anymore; it does not recognize that I have an account while in Explorer this problem does not occur.

    When I tried to open my LinkedIn-profile it does not connect me anymore to my profile. I cannot login with my e-mailaddress and password. LinkedIn does not recognize that I have an account. When I try the same with Explorer this problem does not occur and I can access my profile without any problem.

    GO to appleid.apple.com, click on manage my account and click on security. Answer your security questions to be able to edit your rescue email. If you forget the answers to your security questions, call apple support and request to be connected to a senior adviser or security who can reset your rescue email

  • My internet accounts preference does not recognize that I have deleted an email address.  It wants to connect to deleted email to send out, HELP

    My email internet accounts does not recognize that I have deleted an gmail account.  It wants to connect before it sends a message.  How do I change this?  I thought I changed all my settings to reflect my new mail address - but I must have missed one.

    That was a bit of a bonehead move.  Did you actually change the email address associated with the Apple ID before deleting the email account?

    That's another bad idea.

    Yeah, because the email associated with the Apple ID is deleted and the account is having issue.
    Stop using the new Apple ID.
    Log into the original Apple ID.  Change the email address associated with the Apple ID.
    It should then be possible to update the apps associated with the original Apple ID.

  • Firefox does not recognize SSL Certificate issuer Entrust Certification Authority – L1K, but Entrust Certification Authority – L1C is ok?

    We have a new Entrust SSL Certificate with issuer Entrust Certification Authority – L1K which Firefox does not recognize. Internet Explorer and Chrome are ok.
    On a different system we have an Entrust SSL Certificate with issuer Entrust Certification Authority – L1C which is ok with Firefox.

    Did you verify that all intermediate certificates are installed on the server?
    You can inspect the certificate chain via a site like this:

  • My computer no longer recognizes my iPod Touch. And the iPod Touch does not recognize that it is connected to a computer.

    My computer no longer recognizes my iPod Touch. And the iPod Touch does not recognize that it is connected to a computer.  It has worked great for many days until today.
    I’ve tried two different Apple cables.
    I’ve tried different USB ports on the computer.
    I have rebooted both the Mac and the iPod.
    I’ve wiggled the cables and checked for dust in the connectors.
    The iPod charges using this same cable connected to wall wart.  That’s a good sign.
    Both the Mac and iPod seem to work fine separate from each other.  They just won’t talk anymore.
    Mac mini
    1.83 GHz Intel Core Duo
    OS 10.4.11
    iTunes 9.2.1
    iPod Touch 32GB, version 3.1.3 (7E18), model PB533LL 

    I found this possible solution on another support thread, so I tried it.
    turn off iPod
    hold Sleep and Home buttons to start it.
    When Apple appears, let go of Sleep button, but keep holding Home button.
    When screen goes blank, let go of Home button.
    Connect cable and check iTunes to see if it has conencted.
    This did not work for me.
    I then turned off the iPod, restarted the Mac, and restarted the iPod normally.
    I connected them with the cable, and it works like normal.  :-)

  • Lightroom 5 apparently does not recognize that Photoshop is installed.

    I just installed Lightroom 5, and it does not seem to recognize Photoshop CS5.1, which has been installed for some time. When I click Photo>Edit In, the option for Photoshop and all of the other related Photoshop options, such as Merge to Panorama, etc., are not active, so clicking on them does nothing. This occurs when Photoshop is open. It's as if Photoshop is not installed. Is there something I need to do to ensure that Lightroom 5 recognizes that Photoshop is installed?
    I'm not sure whether the problem is that Lightroom does not recognize that Photoshop is installed or that there is some problem that prevents access to Photoshop from Lightroom.
    I am using Windows 7. In Preferences for external editing, I have the following settings: File Format = TIFF; Color Space = ProPhotoRGB; Bit Depth = 16 bits; Resolution = 240; Compression = None.

    I guess that the problem could be caused by 32bit and 64bit mismatch. Both applications should be 32bit or both should be 64bit.

    Install the 32bit version. FF is a 32bit application even on a 64bit platform.

  • HT3819 My iPad will not allow me to type in my password. Curser is blinking but what i begin typing it just does not recognize that i am printing

    Is there any process I can use to allow me to type into my iPad my password. When I open up the device it sets itself up for me to type in my password. The cursor is blinking, the key pad comes up but it does not recognize that I am typing in the password. The cursor remains in the same position. However it will still play a sideshow of my photos, play music but I cant get into the iPad to operate it to get emails, or operate Safari etc. Is there any thing I can do other than take it to a technician? .

    "Although you can browse the iTunes Store in any country without being signed in, you can only purchase content from the iTunes Store for your own country. This is enforced via the billing address associated with your credit card or other payment method that you use with the iTunes Store. You can use the iTunes Store in all countries of which you’re a resident, but you’ll either need a separate iTunes Store account for each one, or you’ll need to continually be switching your billing information on your single account. Generally, it’s simpler just to set up an alternative account for these situations."

  • Aperture does not recognize that there are images to be imported on an SD card. My workaround is to copy the images from the ST card to a folder and then import the images from the folder. Aperture also imports incredibly slowly after the update to 3.4

    Aperture does not recognize that there are images to be imported on an SD card. My workaround is to copy the images from the SD card to a folder and then import the images from the folder. Aperture also imports incredibly slowly after the update to 3.4

    Check your Import settings in the Import Panel, i.e. all that might exclude the image type you want to import:
    If you did not exclude any file types, and still Aperture will not import, remove your ImageCapture preferences fro your user library:
    To remove the image capture preferences:
    If Aperture is running, quit Aperture,  and log off and on again.
    Open your user library from the Finder's Go menu: Hit Command Shift G (⌘⇧G) and then type in: ~/Library/Preferences/  then hit return.
    In the window that opens remove "com.apple.ImageCapture.plist"
    and look into the subfolder "ByHost": if there are files named com.apple.ImageCapture  something .plist  remove them too.
    then try again.
    And if that still does not help, remove the Aperture preferences as well:
    ~/Library/Preferences/aperture.plist
    Regards
    Léonie
    P.S. in MacOS Lion and later the user library ~/Library is hidden by default.
    You can reveal it also  from the Finder's "Go" menu:
    Finder > Go,   then hold down the options ⌥ key, until the Library appears in the drop-down menu, select it and open the Library folder. Then go to the "Preferences".

    My MobleMe calendar upgrade does not recognize that OS X6.3 has been installed and sees the old OS. What to do?

    visard229,
    Numerous Apple support articles state that "Mac OS X v10.6.4 Snow Leopard is recommended for all users."
    Why do you think that 10.6.3 will work with the MobileMe calendar?

  • When I try to click on a download link for a .pdf file Firefox does not recognize the MIME type and tries to download the file as "index.php"

    When visiting a site I frequent I tried to download a linked .pdf file. Previously I've used Firefox 7.0.1 to download the link with no problem. Using Firefox 8 however I the browser does not recognize the .pdf link's mime type. Instead of recognizing the download link as a .pdf file Firefox 8 tries to download it as "index.php". Firefox 8 does this with .doc files and .txt files as well. When I downgrade to 7.0.1 again the problem disappears.

    Hi hakmacpace,
    I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well.
    You could also try [https://support.mozilla.org/en-US/kb/Managing-profiles?s=create+a+new+profile&r=2&e=es&as=s#w_creating-a-profile Creating a new profile].
    Hopefully this helps!
