How to prevent uninstall/removal of add one from toolbar?

Geplaatst

Hi all,

I would like to know, how I can prevent the uninstall of addons from the toolbar menu? Even if I decide to remove them from the toolbar with customize, I can still uninstall them after moving them back up to the toolbar with customize.

Is there some add on that password locks this from happening?

My reason for doing this is because I have lots of younger relatives who use my laptop sometimes to play games. I want to make sure they are safe on the internet and not messing around with key settings.

Thanks in advance!

You can lock extensions to prevent them from being removed and you can lock access to the about:addons page via a policies.json file.

Hi,

Thanks for reply.

I've got ahead and made a notepad file with the Extension control code in my Firefox Distribution folder, but it didn't seem to work.

Here's what my code looks like:

{

 "policies": {
   "Extensions": {
     "Locked":  ["addon_id@mozilla.org"]
   }
 }

}

Not sure what I'm doing wrong.

You need to replace "addon_id@mozilla.org" with the actual ID of the extension that you want to lock. Easiest to get the ID is to install the extension and look for it on the about:debugging page.

By the way, if Windows says your policies.json file is a Notepad or Text file, there could be a hidden .txt extension on the file name. To take firmer control of file naming, you could set Windows to show all file extensions, at least temporarily.

Would this be something I'd have to do for each individual add on? Also, would the code still work if I list every extension control parameters in the same bracket?

Thanks, but I already had that option enabled. I did add the .txt to the end though.

Sorry, you do not want .txt at the end. You want .json to be the true file extension.

You need to replace "addon_id@mozilla.org" with the actual ID of the extension that you want to lock.

Easiest to get the ID is to install the extension and look for it on the about:debugging page.

Would this be something I'd have to do for each individual add on? Also, would the code still work if I list every extension control parameters in the same bracket?

The [] holds an array, which is a comma-separated list of quoted items. So for example:

[ "{73a6fe31-595d-460b-a920-fcc0f8843232}", "jid1-93WyvpgvxzGATw@jetpack", "savepage-we@DW-dev" ]

To get the IDs, you also can consult the Extensions section of the Troubleshooting Information page. Either:

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

Scroll down past "Application Basics" and "Firefox Features" to "Extensions". The friendly name is on the left and the ID is on the right.

You only need a comma as separator for multiple items in the array ["<id-1>","<id-2>"] and no trialing comma before the closing bracket.

{
  "policies": {
    "Extensions": {
      "Locked":   ["{dd3d7613-0246-469d-bc65-2a3cc1668adc}"]
    }
  }
}

It doesn't seem to be working for me. If I go to the Firefox Addon page, I can simply click remove and it removes it.

If you mean the extension's page on the AMO (Add-ons) website then this is likely this bug that was recently fixed for Firefox 68.1 ESR (and 69/70).

Also, to clarify, If I have the locked function in my .json file, It should prevent any ability to "remove extension" if Firefox is up to date?
