问题 Because it isn't possible to use Greasemonkey for this, I want to write a Chrome extension that will reload a page if it initially failed to load. I know how to write a Chrome extension, I've already injected scripts and figured out how to communicate with pages, so I have basic knowledge of how tabs work and how to build my manifest.
