Hi,

I recently installed the "Block Site" extension for Firefox and
customized it to block certain sites. It's great that I could add a
custom password so that other users here could not bypass the plug in
for a set amount of time BUT they could easily uninstall it.

I'd like to lock the extension, with its current configuration, so that
no one could either change settings or uninstall it. I am using Firefox
on Ubuntu 22.04.

I tried to create an AI inspired policies.json file as described here:

https://tinyurl.com/8knyu4e8

The AI first suggested to find the ID of the extension, which I thought
I did and then created the policies.json files with the following code:

{
"policies": {
"Extensions": {
"Locked": [54e2eb33-18eb-46ad-a4e4-1329c29f6e17]
}
}
}

I tried placing this file first in
/home/jackson/.mozilla/firefox/distribution

as recommended elsewhere. The "distribution" folder did exist, so I
created one. Nothing happened after restart and trying to uninstall the plugin, so tried placing policies.json in two other places:

/usr/lib/firefox-esr/distribution/policies.json

and I believe /etc/firefox/distribution/policies.json

In neither case was the distribution folder there and I had to create
it.

Again, no effect on the extension, whether I tried to uninstall or
modify it.

Any help in this regard would be welcome. Please note that I use the
non-snap version of Firefox.

Thanks in advance.

The extensions id is {54e2eb33-18eb-46ad-a4e4-1329c29f6e17}, including
the curly brackets.

Also, have a look here: https://mozilla.github.io/policy-templates/#extensionsettings
"force_installed" may be what you want.
