## Build wrapped Firefox with extensions and policies
|
|
|
|
The `wrapFirefox` function allows to pass policies, preferences and extension that are available to firefox. With the help of `fetchFirefoxAddon` this allows build a firefox version that already comes with addons pre-installed:
|
|
|
|
```nix
|
|
{
|
|
myFirefox = wrapFirefox firefox-unwrapped {
|
|
nixExtensions = [
|
|
(fetchFirefoxAddon {
|
|
name = "ublock"; # Has to be unique!
|
|
url = "https://addons.mozilla.org/firefox/downloads/file/3679754/ublock_origin-1.31.0-an+fx.xpi";
|
|
sha256 = "1h768ljlh3pi23l27qp961v1hd0nbj2vasgy11bmcrlqp40zgvnr";
|
|
})
|
|
];
|
|
|
|
extraPolicies = {
|
|
CaptivePortal = false;
|
|
DisableFirefoxStudies = true;
|
|
DisablePocket = true;
|
|
DisableTelemetry = true;
|
|
DisableFirefoxAccounts = true;
|
|
FirefoxHome = {
|
|
Pocket = false;
|
|
Snippets = false;
|
|
};
|
|
UserMessaging = {
|
|
ExtensionRecommendations = false;
|
|
SkipOnboarding = true;
|
|
};
|
|
};
|
|
|
|
extraPrefs = ''
|
|
// Show more ssl cert infos
|
|
lockPref("security.identityblock.show_extended_validation", true);
|
|
'';
|
|
};
|
|
}
|
|
```
|
|
|
|
If `nixExtensions != null` then all manually installed addons will be uninstalled from your browser profile.
|
|
To view available enterprise policies visit [enterprise policies](https://github.com/mozilla/policy-templates#enterprisepoliciesenabled)
|
|
or type into the Firefox url bar: `about:policies#documentation`.
|
|
Nix installed addons do not have a valid signature, which is why signature verification is disabled. This does not compromise security because downloaded addons are checksumed and manual addons can't be installed. Also make sure that the `name` field of fetchFirefoxAddon is unique. If you remove an addon from the nixExtensions array, rebuild and start Firefox the removed addon will be completly removed with all of its settings.
|
|
|
|
## Troubleshooting {#sec-firefox-troubleshooting}
|
|
If addons do not appear installed although they have been defined in your nix configuration file reset the local addon state of your Firefox profile by clicking `help -> restart with addons disabled -> restart -> refresh firefox`. This can happen if you switch from manual addon mode to nix addon mode and then back to manual mode and then again to nix addon mode.
