Disable the XPI installs

Subject: config used to Disable XPI parameter of installs (addons) that eliminated in FF 7?

This pref is no longer there by default, but will still work, when you create a new Boolean pref with that name.

To prevent users from installing the software using:

lockPref("xpinstall.enabled" ,false);

Use a mozilla.cfg file in the Firefox program folder to lock the prefs or specify default values.

Place a local file - settings.js in the defaults\pref folder where you will also find the channel - prefs.js to specify using mozilla.cfg file.

pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift

You can use these functions in mozilla.cfg:

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session
lockPref();     // lock pref, disallow changes

See:

(you may need to try again later if the mozillaZine KB does not respond)

  • How can I disable the automatic installation of updates for Vista?

    HP Pavilion dv2 laptop... Vista

    I use my phone sparingly & almost exclusively in public presentations.  I have recently (in response to a popup) changed the setting so that Windows updates are installed automatically.  Since then I have had 2 thoughts, because I don't want that Windows updates (reboots, etc.) could interfere with some presentation planned (or current).

    Where can I change this setting?

  • disable the automatic driver install windows 7 Home premium

    I have a problem installing my dell AIO 922 printer. It is said that I should avoid windows install the drivers.

    Like the windows version family premium is not a policy editor group that I need to know what to change in the registry to prevent the installation of the drivers when I connect my USB printer so I can let the driver installation program with dell windows do its work.

    Anyone know how to disable the automatic installation of the driver without the Group Policy Editor?

    Thank you

    Hello, Willem.

    Make a test with the steps below:

    -Click Start (lower left corner of the desktop)
    -Right click on "computer" and select Properties.
    -On the left side, just below the tasks, select "Device Manager".
    -Locate your device, right click and select Properties.
    -Select the tab 'pilot' and click on uninstall.
    -Click ok and restart the computer.

    If this isn't the case, the only workaround for this problem is to install the latest driver on the manufacturer's Web site to overwrite the current driver.

  • Firewall Windows disable the Internet Explorer loads Up after slow start after the installation of Windows updates

    Hello, (this the mystery of on and Off and back on Windows Firewall with slow loading of programs like Internet Explorer as this all is pass it on firewall, disable the firewall, the firewall, it occurs only during starts, after he fine / but very annoying on reboots whom he accuses of my computer down) / listed below is the cause of it , and when she first started, you have a solution?

    I recently installed the last 16 (High Profile) updates to security, for most security updates and updates from net framework as well as the removal of malware for windows XP tool.

    After installing these updates, now my Windows Firewall turns off during 'Boot Up' on all restarts. If I try to load Internet Explorer, it will also not load up to minutes serveral / while this happens... That's fine, then finally my firewall itself loads Up quickly turns to Internet Explorer and back on during this time around the same time.

    After these updates these things are happening on my computer now, it's as if there is a process running, but nothing run any virus, Trojan or worm etc just these updates caused this problem. I don't know if it updates is corrupt or not, but have tried different things as system file checker /scan etc with no luck.

    (1) computer boots to the top and seems to Load Up Fine ' until the ' or 'Look at this' but isn't, something is running in the background or process "wing unstalled" is obviously "unhooked", etc..

    2) try to load Internet Explorer last minutes and is very slow to load up, even if I 'don't load Internet Explorer' must still a long while that as in the firewall turn off for awhile some several «minutes» (way too long), before "auto turn on automatically return.

    (3) turns firewall Windows itself on "finally" as Internet Explorer finally loads upwards as well the two Internet Explorer is able to load 'definitely' and the firewall is on "finally" as many minutes later as listed above, at the same time.

    This could be the cause? Only, it has begun to 'After' I ran windows update and installed the 'most recently high security updates for windows XP' there were 16 listed mainly security updates and updates of net framework as well as the software removal tool windows malware.

    That's all that is changed on my system, I tried many things, nothing seems to fix this problem with my computer. I know for a fact that these updates are the cause, but am not sure that you caused it? Or how do to solve this problem, any sugguestions would be appreciated.

    Please answer questions following diagnosis by number in your very next answer (no need to quote this post):

    1. what application or antivirus security suite is installed and your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

    2 a Norton or McAfee application already installed on the computer?

    3. do you have a Norton or McAfee free trial come preinstalled on the computer when you bought it? (No matter if you have never used or activated).

    4. you are using IE6, IE7 or IE8?

    5. have you ALREADY had the opportunity to do a Repair Installation of Windows XP for some reason any?

  • The MSI installation, how to disable functions online (like clouds and the connection)?

    How can I disable online features that require a connection with the adobe id? I want to do this while I install the controller of domain Adobe Reader with the MSI installer.

    Hi Matilda,.

    I understand your concern, but Document Cloud is an essential part of the DC of Adobe Acrobat Reader and Adobe Acrobat DC so it cannot be disabled. If you don't want to use this feature then you don't need to connect.

    If you really feel that it doesn't suites your requirement you can uninstall & re-install Adobe Reader 11 Adobe Acrobat Reader DC install for all versions.

    Let me know if you have any additional questions.

  • New installation of SQL Server, disable the write cache?

    Hello, I'm under ESXi 5.1 and I need to configure a virtual machine Windows server 2012 for our first virtual SQL Server.  My database guy tells me that I have to disable the cache write for SQL best practices.  Is it always true when it is a virtual machine?  If it is true where would I turn it off?  To add a bit more info about our storage on a network SAN Dell EqualLogic and we will use SQL 2008 as SQL 2012 is not yet supported.  Thanks for the help!

    I think that your SQL guy assumes the ESXi host will be caching on its own transparent for the VM by default. This is incorrect, ESXi does nothing like that.

    The only place where caching of write i/o can happen is on the side of physical storage outside ESXi, so in your case the SAN controllers (no reason not to have this license here too long as it is on battery/flash) or the discs themselves (ugh, it is never enabled by default for a good reason).

    BTW: I'm pretty sure that SQL 2008 is not supported on Server 2012.
