How to block extension using policies.json
Hi, I planned to block my users from installing extensions/add-ons. I found an article that might be the answer (https://support.mozilla.org/en-US/questions/1308646). I tried to create a simple policy (below), but somehow it does not work (I can still install any add-on/extension). What is wrong with my script? I'm using Firefox ESR 78.11.0 (64-bit) by the way.
My "policies.json" looks like this:
{
"policies": {
"ExtensionSettings": {
"*": {
"blocked_install_message": "Blocked!",
"install_sources": ["https://addons.mozilla.org/"],
"installation_mode": "blocked"
}
}
}
Sincerely, Jonathan

See:
Note that your curly brackets do not match as you need to add one more '}'. You should see an error on about:policies#errors.
{
"policies": {
"ExtensionSettings": {
"*": {
"blocked_install_message": "Blocked!",
"install_sources": ["https://addons.mozilla.org/"],
"installation_mode": "blocked"
}
}.
}
