How can I add popup-exceptions into mozilla.cfg?
Hi there
I have a mozilla.cfg file that configures some settings in Firefox. All the configurations are adapted except the popup configuration and the configurations bellow the popup-configuration.
After firefox is installed I check the popup exception list but there is no entry.
This ist the code in mozilla.cfg
//RhB-Popup Exceptions Components.utils.import("resource://gre/modules/Services.jsm"); var uri = Services.io.newURI("http://rhbekse", null, null); Services.perms.add(uri, "popup", 1); var uri = Services.io.newURI("http://rhberpws.intra.rhb.ch:8080", null, null); Services.perms.add(uri, "popup", 1); var uri = Services.io.newURI("http://rhberpwsint01.intra.rhb.ch:8080", null, null); Services.perms.add(uri, "popup", 1); var uri = Services.io.newURI("https://www.rhb.ch", null, null); Services.perms.add(uri, "popup", 1);
Did I do anything wrong?
thank you for any help

Moving to Firefox for Enterprise.
Note that you can no longer run privileged JavaScript in Firefox release versions (still works properly in ESR) because this code runs in a sandbox.
You can check the Browser Console for any messages related to the autoconfig file.
- "3-bar" menu button or Tools -> Web Developer
- https://developer.mozilla.org/en-US/Tools/Browser_Console
You can add this line to the autoconfig.js file that specifies using autoconfig.cfg
- pref("general.config.sandbox_enabled", false);

Isn't autoconfig.cfg only after the installation available? Where is the file?
Since you stated that you use an autoconfig, I skipped the steps about the two required files. You can specify the name of the cfg file in the autoconfig.js and this file can have name. Currently the preferred name is autoconfig to get in line with the docs.
You can use the autoconfig.cfg file in the Firefox program folder to initialize (set/lock) preferences and run privileged JavaScript code.
The autoconfig.cfg file needs to be in the main Firefox program folder *https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig
- https://support.mozilla.org/en-US/kb/customizing-firefox-using-policiesjson
- https://github.com/mozilla/policy-templates/blob/master/README.md
This requires a autoconfig.js file in the "defaults/pref" folder where the channel-prefs.js file is located that specifies to use autoconfig.cfg.
//
pref("general.config.filename", "autoconfig.cfg");
pref("general.config.obscure_value", 0);
pref("general.config.sandbox_enabled", false);
The autoconfig.cfg and autoconfig.js files need to start with a comment line (//).
See Configuration:
None of this Component importing in mozilla.cfg worked for me either (Ubuntu 18.04/Firefox 67) - I ended up digging through breadcrumbs in the Mozilla support site and discovered the solution is via Policy Settings, using the PopupBlocking policy.
The short how to:
- Create /usr/lib/firefox/distribution/policies.json
- Populate it as per below
- Validate your config by restarting the browser and going to about:policies
My policies.json:
{
"policies": {
"PopupBlocking": {
"Allow": [
"http://popuptest.com",
"https://docs.google.com",
"https://drive.google.com",
"https://mail.google.com"
]
}
}
}
I've also documented this in a bit more detail on reddit:
