feat: add support for Firefox data collection permissions

[suveshmoza]

Overview

Adds support for Firefox's required data_collection_permissions field in browser_specific_settings.gecko. As of November 3rd, 2025, all new Firefox extensions must declare their data collection practices.

Changes

• Add FirefoxDataCollectionType and FirefoxDataCollectionPermissions TypeScript types
• Update UserManifest to include data_collection_permissions in browser_specific_settings.gecko
• Add warning when building for Firefox without data_collection_permissions #specified

Manual Testing

Building the wxt-demo for Firefox will show a warning to add data_collection_permissions to manifest config.

I'm concerned that devs will see the warning and get mad that the only way to silence it is to add the option. I'd be nervous to do that because I'm not sure if adding, even a blank object, could result in the extension being disabled since the manifest changed in a way that the prompt also changed. I'd like to add a config option to silence this if the dev doesn't want to address it yet.

Thoughts?

I agree with your concerns. The warning could frustrate developers, especially those maintaining existing extensions, who are currently exempt but will eventually need to specify these permissions.

Yes, a config option would be nice and could be extended for future warnings. Something like

export default defineConfig({
  suppressWarnings: {
    firefoxDataCollection: true,
  },
  // ... rest of config
});


if (
  wxt.config.browser === 'firefox' &&
  !userManifest.browser_specific_settings?.gecko?.data_collection_permissions &&
  !wxt.config.suppressWarnings?.firefoxDataCollection //using config option here to silence warning
)

3. Map the user config to the resolved config:

   wxt/packages/wxt/src/core/resolve-config.ts

   Line 40 in 223cf86

   export async function resolveConfig(

   You should see a type error in this file after changing the types.

Then we can also a message to the warning about how to set the config to suppress the warning.

3. Map the user config to the resolved config:

   wxt/packages/wxt/src/core/resolve-config.ts

   Line 40 in 223cf86

   export async function resolveConfig(

   You should see a type error in this file after changing the types.

Then we can also a message to the warning about how to set the config to suppress the warning.

Should I include this with current PR or create a separate one?
