The PDF viewer's "save with changes" feature uses `window.showSaveFilePicker()`, but the PDF extension runs in a cross-origin iframe (chrome-extension:// inside the app's origin). Chromium's File System Access API blocks cross-origin subframes from showing file pickers unless the embedder explicitly allows them via `ContentClient::IsFilePickerAllowedForCrossOriginSubframe()`. Chrome overrides this in `ChromeContentClient` to allowlist the PDF extension origin, but Electron never did — so the picker was always blocked with a SecurityError. This adds the same override to `ElectronContentClient`, allowing the built-in PDF extension origin to bypass the cross-origin check.

The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. It is based on Node.js and Chromium and is used by the Visual Studio Code and many other apps.

Installation
To install prebuilt Electron binaries, use npm.
The preferred method is to install Electron as a development dependency in your
app:
npm install electron --save-dev
For more installation options and troubleshooting tips, see installation. For info on how to manage Electron versions in your apps, see Electron versioning.
Platform support
Each Electron release provides binaries for macOS, Windows, and Linux.
- macOS (Monterey and up): Electron provides 64-bit Intel and Apple Silicon / ARM binaries for macOS.
- Windows (Windows 10 and up): Electron provides
ia32(x86),x64(amd64), andarm64binaries for Windows. Windows on ARM support was added in Electron 5.0.8. Support for Windows 7, 8 and 8.1 was removed in Electron 23, in line with Chromium's Windows deprecation policy. - Linux: The prebuilt binaries of Electron are built on Ubuntu 22.04. They have also been verified to work on:
- Ubuntu 18.04 and newer
- Fedora 32 and newer
- Debian 10 and newer
Electron Fiddle
Use Electron Fiddle
to build, run, and package small Electron experiments, to see code examples for all of Electron's APIs, and
to try out different versions of Electron. It's designed to make the start of your journey with
Electron easier.

Programmatic usage
Most people use Electron from the command line, but if you require electron inside
your Node app (not your Electron app) it will return the file path to the
binary. Use this to spawn Electron from Node scripts:
const electron = require('electron')
const proc = require('node:child_process')
// will print something similar to /Users/maf/.../Electron
console.log(electron)
// spawn Electron
const child = proc.spawn(electron)
