We understand that many PDFs contain sensitive information, however having a PDF is essential to resolving the issue and building our regression testing suite. If possible, try creating a reduced example exhibiting the problem but not containing sensitive data. Also small PDFs are best suited for our regression testing.

-## Overview
-
-Example to demonstrate PDF.js library usage with Browserify.
-
-## Getting started
-
-Build project and install the example dependencies:
-
-    $ gulp dist
-    $ cd examples/browserify
-    $ npm install
-
-To build Browserify bundles, run `gulp build`. If you are running
-a web server, you can observe the build results at
-http://localhost:8888/examples/browserify/index.html
-
-See main.js, worker.js and gulpfile.js files. Please notice that PDF.js
-packaging requires packaging of the main application and PDF.js worker code,
-and the `workerSrc` path shall be set to the latter file. The pdf.worker.js file
-shall be excluded from the main bundle.
-
-Alternatives to the gulp commands (without compression) are:
-
-    $ mkdir -p ../../build/browserify
-    $ node_modules/.bin/browserify main.js -u ./node_modules/pdfjs-dist/build/pdf.worker.js -o ../../build/browserify/main.bundle.js
-    $ node_modules/.bin/browserify worker.js -o ../../build/browserify/pdf.worker.bundle.js

+ * Released under the MIT license
+ * https://github.com/Rob--W/chrome-api/chrome.tabs.executeScriptInFrame
+ *
+ * Implements the chrome.tabs.executeScriptInFrame API.
+ * This API is similar to the chrome.tabs.executeScript method, except
+ * that it also recognizes the "frameId" property.
+ * This frameId can be obtained through the webNavigation or webRequest API.
+ *
+ * When an error occurs, chrome.runtime.lastError is set.
+ *
+ * Required permissions:
+ * webRequest
+ * webRequestBlocking
+ * Host permissions for the tab
+ *
+ * In addition, the following field must also be set in manifest.json:
+ * "web_accessible_resources": ["getFrameId"]
