Description
Is this a feature request or a bug?
Bug.
What is the current behavior?
When running webExt.cmd.run in a NodeJS script, Firefox fails to open, and web-ext fails with the following error:
file:///path-to-extension/node_modules/web-ext/lib/firefox/remote.js:92
throw new WebExtError(`installTemporaryAddon: Error: ${message}`);
^
WebExtError: installTemporaryAddon: Error: Error: Could not install add-on at '.': [Exception...

Node.js v21.4.0Everything works as expected when passing target: chromium as an option, and Chromium launches with the extension loaded. The issue only occurs in Firefox. There are also no issues when web-ext is run via the command line, and Firefox launches as expected:
npx web-ext run --source-dir=.The issue only occurs when using web-ext in a NodeJS script.
Steps to reproduce
- This bug appears to be independent of the extension used. One should therefore be able to reproduce this bug with any minimal extension. To create a MRE, I used one of the example extensionslons:
git clone git clone https://github.com/mdn/webextensions-examples.git && cd webextensions-examples/beastify- Create the file
package.jsonwith the following contents:
{
"type": "module",
"devDependencies": {
"web-ext": "^7.9.0"
}
}- Run
npm install. - Create a file
run.jswith the following contents:
import webExt from 'web-ext';
webExt.cmd.run({sourceDir: '.'});- Run
node run.jsand observe the above error. - Execute
npx web-ext run --source-dir=.and observe that Firefox launches without issue. - Modify the file
run.jsto have the following contents:
import webExt from 'web-ext';
webExt.cmd.run({sourceDir: '.', target: 'chromium'});- Run
node run.jsagain and observe that Chromium launches without issue.
What is the expected or desired behavior?
Firefox should launch as it does when running npx web-ext from the command line.
