How can I remove Firefox update?

It was corrupted once I downloaded it with a slow connection
I want to go back to Firefox 41.0.0

Sorry, but there is no way to roll back an update except by downloading a fresh Installer. Here is how I suggest to proceed:

Clean reinstall it

We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (not incompatible, corrupt or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.

(A) download a fresh Installer for Firefox 41.0.2 of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

(B) the release of Firefox (if any).

(C) simply rename the folder of the current programme, either:

(Windows 64-bit folder names)

C:\Program Files (x86)\Mozilla Firefox

TO

C:\Program Files (x86)\OldFirefox

(Windows 32-bit folder names)

C:\Program Files\Mozilla Firefox

TO

C:\Program Files\OldFirefox

(D) run the installer downloaded to (A). It should automatically connect to your existing settings.

Firefox works normally?

Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

Otherwise, there is no reason to keep the old folder except research/curiosity.

    I do not use Windows at the present time. Not sure if Firefox did not update a option now. Personally I would not downgrade to version 17 it is not secure and does not have the latest patches. If you wish to make in order to follow the link in this article. Install an older version of Firefox

    A better option

    disclaimer - this is not official advice
    - this procedure is NOT supported by support.mozilla
    - and is not recommended for personal use
    

    Use the ESR version, at least it is safe and will use Fx17 soon.

    If you do not need updates to block there are possible ways (but not necessarily on the ESR) it is to get rid of the address update string.

    Hello

    > How to remove a Bios Update?
    I think you want to Flash the BIOS to the original version.

    You can't do this because you n t have the first version of BIOS.
    In addition, there is a version of the traditional BIOS update that is not available on the European driver Toshiba page.
    So your last option would be the Toshiba ASP in your country!
    You will need to contact the guys for the first version of BIOS.

    Just a hint; never change a running system ;)

  • How can I remove an update which has no KB number on it?

    If I review my editing history, I see the following entry:

    product: xp

    Update: Zoom - other hardware - Zoom Virtual Audio Device

    status: green arrow

    Date: 30/09/11

    Source: Microsoft Update

    =====================

    This update has been installed via windows update on the microsoft Web site. I would like to remove this update, but I can't find the update in 'Control Panel, add or remove programs (with the updates to see the check mark).

    Microsoft technical support said they are not without a certain number of KB updates, so it must be a virus. My antivirus (Kaspersky) standard software shows no problem and even once, I installed via windows update.  How can I uninstall this patch?

    This seems to be an update of the driver.  Establishing general principles, you should never install drivers from Windows Update; all you need are 'critical' updates - not "optional" updates

    If it's a driver, it will not appear in Add or Remove and there is a number of KB (the one who tells you otherwise is either misinformed or was not thought about drivers).

    Why do you want to remove?  You're having problems with your audio files?

    See the old thread on what seems to be the same problem--> http://www.vistaheads.com/forums/microsoft-public-windowsupdate/201827-received-possible-false-hardware-update-windows-update.html
    Read all the messages.

    Feel free to try "patches" described in this thread, but if you encounter a problem with a specific device that seems to have been caused by an incorrect installation of the driver Zoom, I suggest to uninstall the device and then re-setup using a pilot freshly downloaded.  Download the current from your computer manufacturer driver (especially if you have a laptop) or the manufacturer of the device.
