Disable Updates in Firefox 63 and above

Starting in Firefox 63, it is not possible to disable updates of the browser. Developers have removed the appropriate option from the browser's settings. Here is a solution you can apply.

Firefox 63 About

Firefox 63 represents the branch built with the new Quantum engine. It comes with a refined user interface, codenamed "Photon". The browser now comes without support for XUL-based add-ons, so all of the classic add-ons are deprecated and incompatible. See

Must have add-ons for Firefox Quantum

Starting in version 63, Firefox no longer includes the option to completely disable updates. The option "Never check for updates" has been removed from the Preferences\General section. The options you can set now are:

  • Automatically install updates(recommended)
  • Check for updates but let you choose to install them

Firefox 63 No Disable Updates Option

Developers have added a special policy to Firefox that administrators can apply to stop Firefox from updating.

To disable Updates in Firefox 63 and above, do the following.

  1. Close Firefox.
  2. Open the Registry Editor app.
  3. Go to the following Registry key.

    See how to go to a Registry key with one click.

  4. Create a new subkey here named Mozilla. You will get the path HKEY_LOCAL_MACHINE\Software\Policies\Mozilla.
  5. Under the Mozilla key, create a new subkey Firefox. You will get the path HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox.
  6. On the right, create a new 32-Bit DWORD value DisableAppUpdate.
    Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value.
    Set its value to 1.Firefox 63 Disable Updates
  7. You can open Firefox. The updates are now disabled.

Firefox 63 Updates Disabled

To undo the change, remove the DisableAppUpdate 32-bit DWORD value you have created, then restart Firefox.

To save your time, you can download the following ready-to-use Registry files:

The undo tweak is included.

Alterivate Solution

There is an alternative solution suggested by our reader EP. You can create a policies.json file and store that file into the ‘C:\Program Files\Mozilla Firefox\distribution’ folder. Create a ‘distribution’ folder in \Program Files\Mozilla Firefox\ folder and place that policies.json file into that folder with the following contents:

     "DisableAppUpdate": true

That's it.

    Here is the source of the removal: https://bugzilla.mozilla.org/show_bug.cgi?id=1420514

    Please leave feedback there if you believe “Never check for updates” is not a bug and should be brought back.

    Well we can ‘Never check for updates’ or we can have ‘Never install Firefox again’. Your move Mozilla.

    this registry trick may no longer work, Sergey.

    a better solution is to create a policies.json file and store that file into the ‘C:\Program Files\Mozilla Firefox\distribution’ folder. Create a ‘distribution’ folder in \Program Files\Mozilla Firefox\ folder and place that policies.json file into that folder that has the following code:

    “policies”: {
    “DisableAppUpdate”: true

      Thank you very much. I’ll add this to the article.

      Tried policies.json hack. Did not work Jan 2020.

      Registry hack did. Now Firefox effectively says Updates disabled by your administrator.

        This no longer works with firefox 73.0. I believe anything newer than 70.0 no longer respects policies.json.

    The registry trick seems to still work. And it’s a better solution for scripting or dealing with multiple computers that have Firefox installed. It appears that the developers at Firefox have lost their minds, and decided to play IT Nazi with their own users. The main problem that most people have is the insane nag pop-up that keeps occurring if they don’t select automatic updates. Users should have the freedom to choose when they update Firefox. It would have been vastly smarter for Mozilla to give a choice, like check every 2 weeks or once a month, and then a nag screen would appear requesting an update.

    Having a nag pop-up every time a user opens Firefox because they refuse automatic updates is plain dumb. The only thing Mozilla will succeed in doing is help convert Firefox users over to Chrome, Edge, or some other browser. Furthermore, Firefox updates also can break various Add-ons, because the authors haven’t updated to the new version of Firefox yet. This creates an additional headaches to users, if they choose automatic updates. Going full IT Nazi on users is not the way to go.

    EP’s solution worked for me in FF v.66.0.3 No nag screens for the last four days. Thxs!

  9. Barrie

    Thank you so much!!!!!!

  10. Nelda

    But now I can’t update manually either. I’m not sure which is worse!!

  11. Ahmad Moualla

    I swear i stopped using Firefox because of this annoying problem. You should really worry about your customers!

    registry method works in November 2019.

  13. Firefox 70+ user

    Tried registry mode as of January 2020, works perfectly.
    Went ahead and did the policies.json file in user created “distribution” folder for good measure. We’ll see if they screw this up somehow, too.

    Who is using an old version of Firefox, which he finds reliable?

    The bad news is, that in the world of browers, Firefox is the one that is the least bad. But most certainly their updates are becoming more and more unacceptable.
    I have decided to return to an older version and now want to find people with experience in that….

    It seems every time I take the updates there is a new update trying to come through the next day. The reason it is annoying is because the “update” destroys all my settings and often replaces everything (bookmarks etc) without informing me. AND IT ALWAYS HAPPENS WHEN I ACTUALLY NEED TO DO SOMETHING.

    There is a huge market for an os and browser that is fast, streamlined, ultra secure and not concerned with stealing your personal data.

    Thunderbird recently got rid of the the option to never check for updates. When it is time for an update it will nag you daily. If you create a Mozilla/Thunderbird registry key as per this article it also stops the updating.

  17. Inservio

    I use several different versions of FF, so I prefer using the flags in about:config
    If you only have one version installed, the regkey above is by far the simpler solution
