Why plugins survive a new re - install?

Last night I noticed that I was still on FF 8.x and the current version was 10.x, so I decided to upgrade. My 8.x installation is littered with pieces of old addons, unused on: entries in config (that I don't know how to delete), etc. So I uninstalled, lashed out at his installation folder and its data as part of my User\AppData, both the 'Local' and 'Roaming' folder.

That should be enough... right? Nope.

By opening the freshly installed copy, it had no addons installed, but there has been several plugins installed. They had buttons disable, but no uninstall button. Nor was I warned they were installed/transferred, or given a chance to stop him. (On the first run, I chose to not to import anything)

Why Firefox does? Sounds a little shady to me.

Registration to the topic: config who are left behind after uninstalling Extensions, can be removed by right click on these items and choosing "Reset" which should make the 'Value' column empty. Restart Firefox and the entries should be gone. Uninstall an Extension is not a 'clean' process, just like uninstall your computer system generally leaves behind some registry entries and files/folders on your hard drive.

Plugins are installed by applications, installed on your system, like Adobe Reader (Adobe PDF plugin for Firefox and Netscape), Adobe Flash (Shockwave Flash) Player, RealPlayer, Java, etc. The Plugins are installed by the Windows registry for window systems. You can see the applications in Control Panel > add or remove programs (or programs and features). The Plugins installs in your browser, unless you uninstall applications.

    This isn't really a problem of Microsoft.  Java is Sun Microsystems.  You must have installed on your PC Java runtime environment.  You can disable Java updates in the Panel with the Java applet.  You should not see a daily update, but the updates to Java to get out with some regularity.  In general, Sun Releases Java update when the vulnerabiliites discovered oi the JRE.

    Photoshop CS5 (as well as the versions of the other Adobe Creative Suite 5 applications) are not optimized for the retina on your new computer. They never will be updated.

    You must purchase a subscription to applications of creative cloud or Photoshop CS6 to get support for the Retina display.

  • Repeatedly to get BSOD on Windows 8, even after the new re - installed.

    Hello

    I installed a new copy of Win8 about 3.5 months ago, and last week I started having these BSOD errors (possibly after a windows update):

    1. NTFS FILES for error SYSTEM
    2. IRQL NOT LESS OR EQUAL
    3. LIST OF CORRUPT NFP
    4. SYSTEM SERVICE EXCEPTION

    Everytime I restarted my computer, I had another of these errors. So I decided to update the installation of Windows 8, and because the update remained stuck on 39% more day I left it. At this point, it was simply impossible to connect to windows whenever I tried because the BSOD would leap upward before that windows won't even load.

    Attempts at recovery:

    1. Fully formatted HARD drive, installed Windows 8, but it was just a matter of time until that the BSOD was back again after a windows update. I suspect that these errors are all drivers related issues, but how can we know which driver is causing the conflict exactly? What can I use to read the Dump files easily?
    2. Research showed it could be things like adapters wireless usb etc, and I noticed that my usb adapter list win8 as a compatible platform. I went to the store and bought a usb adapter which is 8 compatible windows. I also bought a HARD disk that is compatible win8 just to be sure. I tried another new facility at the new disk and he succeeded. I installed the driver of usb wireless network card compatible win8 since the accompanying CD and the BSOD was back.
    3. Completely re-formatted the HARD drive tries again, another installation, but once it has reached "Installing updates" IRQL LESS or DIFFERENT error popped up again. I don't think it actually installed updates because the computer was not connected to the network somehow, because the usb adapter is no longer connected to the computer.
    4. I tried to install another after a quick format once again, and when she reaches the "Install updates" step the BSOD came back (no cable Ethernet or a wireless connection to internet).

    Issues related to the:

    1. A full format really helps the situation?
    2. Is it possible to have driver problems during the installation of windows on a hard drive completely wiped out?
    3. Why it would fail to step "Install updates" even if there is no connection to the network, so no way to download the updates?
    4. Is it possible that the other components of my machine cause conflicts?
    5. If not, how can I solve this problem? What are some other things to try?

    Here are the specs of my machine:

    • Graphics, GTX 670 1 800 MB of memory.
    • 16 GB of RAM DDR3 Corsair Vengeance.
    • Processor 3.5 GHz Intel core i7 - 3770 k

    Hello

    It turns out one of my RAM chips was defective.

    I ran a diagnosis of memory, which has detected hardware problems, then I ran my computer with each piece at a time to determine the defective one.

    My computer works fine now. I think that everything else is fine as well.

    I thank very you much for all the help. I'll reach out again if something else happens.

  • I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. Help

    I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. HELP PLEASE. previous e-mail files are under mail then mail.earthlink* .net and each of the five mail .net is an email address I have. I can't find a way to identify each file by email to the specific email address (IE mail.my E-mail name.net) so I can copy the files and emails from the past to the email addresses now under tbird. previous installed e-mail identities may not be the current configuration of e-mail files in tbird. I think that I must be sure that mail.name.net matches the previous mail.name.net to be able to copy and paste the old to the new. is there a way to find the file name correct the old email and correspond to the new? all my emails very important information are mostly in the old mail electronic id and must be available in the identification of email again (but same) how can I do this?

  • Popup "new programs installed" keeps coming back non-stop

    Hello friends,

    Recently, I removed a few very large programs (for example ADOBE more some other things) on my DELL laptop (windows xp with sp 3). Since then, I've noticed that the popup "new programs installed" is displayed all the time. Whenever I click on the Start button, I get the popup and it won't go away. No idea as to what might have happened and how to fix the bug?

    Your contribution is greatly appreciated.

    I'm trying to uninstall Verizon's VZ Access Manager.  I get "invalid UNINSTALL Uninstall Wise. LOG file.  How can I get this off for Verizon can help me to get the new drivers installed?

    Hello retabox, welcome.

    It would seem that the installer is corrupted. I recommend trying to use the Windows Installer Cleanup utility to force - to remove the application. Try this:
    2. click on the download link in the middle of the page
    3. save the file to your desktop or just click Run the installation of the application
    4. once the application is installed, open the utility. The utility must be located in the menu START under (START > programs > Windows Installer...)
    5. in the utility, find the application you want to uninstall, and then click the button 'delete' below
    6. once removed, restart the computer and see if you can reinstall the application
    Let us know if it works,
    Thank you!
