WindowSizer -- Window Resizing WebExtension

A simple, customizeable window resizer

• Define multiple custom width & height presets in options
• Easily switch between them via toolbar menu
• Even more quickly switch between them via hotkeys

Inspired by the old Firefox add-on Browsizer

After upgrading to Firefox 57, I could no longer use Browsizer, and no suitable repalcements were available. So I decided to learn how to write an add-on using the WebExtensions API, and here's what I have come up with so far!

The latest release version is available on the AMO site.
