All browser extensions don't work.

Same issue (with same fmkad.... id).

I found an extremely unpleasant solution. Following the suggestion here:

• Add the latest (unreleased) build of electron-devtools-installer via yarn add git+https://github.com/MarshallOfSound/electron-devtools-installer.git, as suggested here.
• In main.dev.ts, replace installExtensions with this:

const installExtensions = async () => {
  const installer = require('electron-devtools-installer');
  const forceDownload = !!process.env.UPGRADE_EXTENSIONS;
  const extensions = ['REACT_DEVELOPER_TOOLS'];

  return installer
    .default(
      extensions.map((name) => installer[name]),
      { forceDownload, loadExtensionOptions: { allowFileAccess: true } }
    )
    .catch(console.log);
};

• Go into the directory of the extensions themselves. For React Developer Tools on my (Windows) machine, that's C:\Users\<user>\AppData\Roaming\Electron\extensions\fmkadmapgofadopljbjfkapdkoienihi.
  • Delete the _metadata directory.
  • In manifest.json, delete the update_url, minimum_chrome_version, and browser_action entries.
• Upgrade Electron to 12.0.2 (the latest as of writing) via yarn upgrade electron@12.0.2.
• In main.dev.ts, when creating the new BrowserWindow, set contextIsolation to false (I can't vouch for security implications etc of this):

  mainWindow = new BrowserWindow({
    show: false,
    width: 1024,
    height: 728,
    icon: getAssetPath('icon.png'),
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
    },
  });

Then it should work. Clearly not a great solution but perhaps a stopgap. The problem seems to be spread across multiple infrastructure repos, I'm not sure if extensions are working for anyone right now. Then again if they were broken for everyone I'd expect more noise on this issue, I had to dig to find this workaround.

@timsgardner I did not have to upgrade to electron 12 I stayed on 11.4.3 and it still worked

electron-devtools-installer released 3.2.0 already.
however { forceDownload, loadExtensionOptions: { allowFileAccess: true } } not updated yet, and electron-devtools-installer not updated to 3.2.0 yet.
