Cannot install extensions - access denied

I am trying to install an extension, but a message pops up saying that Firefox prevented me from moving it. I'm going to the addon website and try to install from there, but I get another message saying Firefox "cannot change the necessary file. I think I know what it is - the extensions folder in my profile, it's all the 'access denied' - NOTHING I could move I tried through the Security tab, but everything he tells me it is that I need read permissions. I tried to delete the directory via the command prompt, but it tells me the same thing, "access denied"... I'm puzzled! But I have to install this extension!

Never mind; access the file reopened after awhile and I could get my extensions.

  • I cannot install extensions, they appear with "will be installed after you restart Firefox" even after that I restarted.

    Hello

    I cannot install extensions, they appear with "will be installed after you restart Firefox" even after that I restarted.

    The 'Intermediary' folder is present and rest after a restart, but the extensions do not get installed. They show in the extensions page with the message "will be installed after you restart Firefox" and remain like that, no matter how many times I restart.

    Any idea?

    Thank you very much

    P.S. Just tried to install the add-on "convenience store" before asking the question and I got an error saying that it cannot install because it cannot change the necessary file. (I did manually instead)

    I tried to delete the files extensions.* nothing works. However, I deleted the addons.sqlite file and restarted my computer (computer not only Firefox) and that seemed to do the trick. Problem solved.

    Thank you for your help, it is appreciated.

  • RE: Installed detachment "access denied." I have the same problem and none of the above worked. The property is empty, but demand will not accept me.

    RE: "access denied" following the installation of Firefox question. I have the same problem. Details below: I tried opening in Mode safe that has not worked. I have administrative access. When I click on the general tab in properties, I get a message that there is no such thing as "firefox.exe". This file, or any other type 'install' file appears in the directory Mozilla Firefox with the exception of 'uninstall '. I downloaded and tried to install seven times from six different sources, including Mozilla, all with the same results. I also tried a number of solutions on the web for this error without great success. I tried, first of all, to make an upgrade, then remove the old version of Firefox and have been 'install' since then. Avast, Malwarebytes and Threatfire found no malware.

    I've never had a similar problem with Firefox before and I used it for years. Anyone has any ideas that I have not already tried? I'm tired of using Internet Explorer! RE: Troubleshooting below - information Windown will not open the downloaded file.

  • Cannot install bios access from win 8

    HP Touchsmart tm2 laptop and although age has officially supported, was able to install Windows 8.0 but now cannot move to 8.1 Windows because I can't boot from the CD/DVD or USB flash drive.

    The store Windows says that my 8.0 cannot be updated to 8.1 via the shop, so I want to do a fressh 8.1 installation and have purchased the software and the key.  But I can't get the laptoip to boot on the USB CD/DVD or a USB flash drive (or even a floppy disk)

    Since the installation of 8.0, when the computer starts, a HP logo appears, but there is no option to enter the BIOS setup or to specify the boot sequence.   I have no reason to believe that I changed the boot sequence, so there should resemble any of these external devices first, but this is not (there's a brief access to the CD/DCD, but it goes to start with the hard drive).

    It seems that Win 8.0 installation has done something in the BIOS.  Have tired etc. ESC, F2, F10, Del, F6 during the boot process, even if the messages do not appear.   Maybe I could reflash the BIOS?  Or is it an executable I could run wtining Win 8.0 to access the BIOS, otherwise I'm stuck.

    Anyone with a similar problem/solution?

    Thank you

    Was able to get. Window very tight to get into the boot on this computer compared to other menu that I worked.  Configuration via USB seems continues normally.

    I already installed Win 8.1 on a HP TouchSmart300 desktop model and found that the microphone does not (confirmed elsewhere in this forum).  Using a wirelss headset Plantroincs has proved a good solution.  Anticipating I could met the same problem on the laptop.  Now soon.

    Thanks again.

  • Cannot install Extensions in Safari 9.0.1

    I'm on Mac OS X on a MacBook Pro 2013 10.10.5 and I have noticed when I try to install all the extensions that are not the Safari Extensions Gallery, it opens with a window asking you if I trust in it and I click on trust, but the extension does not appear in the extensions list, or anywhere. This was happening on OS X 10.11.1 also. He was working on Safari 8, but not Safari 9.0.1. I have not found any discussion which has helped.

    Please, back up all data before proceeding.

    Launch the Keychain Access application in one of the following ways:

    ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

    ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    Use the search box in the toolbar of the Keychain Access window to find an item named 'Safari Extensions list'. If found, delete it. Quit Keychain Access.

    Quit and restart the Safari app.

  • Safari cannot install extensions

    When I visit https://safari-extensions.apple.com/ I see a message at the top of the screen which seems to suggest that Apple's site I am under an outdated browser / OS combo:

    … Except that I'm not. I'm running Safari 9.1.1 (11601.6.17) on OS X El Capitan (10.11.5). Therefore when the extensions gallery there is no on-screen navigation button / link / anything to install an extension.

  • Cannot install Clean Access Manager Server/Bundle (worm: HP Server 4.0)

    Hi all

    can someone help me with the following questions I encountered during the installation of own server access/Manager in

    HP Proliant DL 360 G5

    Type: SAS

    Controller: Controller HP Smart Array P400

    a. first question is if I can install the two Clean Access Server & Manager in a HP Server

    b. after the server starts on the CD, had break showing the command "being run/sbin / loader."

    When I checked it displays "Waiting for device to be stable 20 seconds."

    c.When I tried to only install the clean access server, after loading anaconda it says "no device valid only found o to create new file systems." Plese check your hardware for the problem.

    Waiting for your valuable response for the same

    CASE and CAM comes as a built... cisco devices is not like a CUCM, Manager of calls where you download the software and put it on a customizable material by you... 3300 servers come on different features... Take a look at the data sheet:

    http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps5707/ps8418/ps6128/product_data_sheet0900aecd802da1b5.html

    3350 and 3390 devices support smart array E200i... and also SAS raid disk controllers...

    b. you must order at least 2 boxes/servers, one for ca and one for CAM... PAK keys/licenses are important here, because the image can be also downloaded EAC, even if you lose the CD... When you order the box, it comes with the basic settings... just for short, you need 1 CAM, 1 CASE, licenses for two then CD are common for SCS and CAM. It's just, you must select the functionlaity in the last step of the installation...

    I hope this helps... all the best...

  • Cannot install extensions in DW CS3 since Photoshop CS6 trial download

    I use Dreamweaver CS3 on Windows XP. A week ago, I downloaded the free 30 day trial of Photoshop CS6. Since then, when I try to install an extension in Dreamweaver, CS6 Adobe Extension Manager opens with the message "this extension can be installed, it requires Dreamweaver version 6 or greater. I looked add & remove programs on my computer to see if the CS6 extensions manager could be uninstalled, but is not on the list of programs so I guess the only way to remove it would be to uninstall the trial of Photoshop, I want to do. Is there a way around this problem? The extension, I tried to install is an update of a PVII product I have already installed.

    In DW CS3, when you select COMMANDS. Manage Extensions, what version of the extension manager opens?

    Have you tried to uninstall the trial SP6?
