ZIP Manager by Lunu

This extension is ZIP format viewer and extractor. You can feed the extension with one or multiple local files or a single remote link and it will display the ZIP contents. You can then extract selected files or all files into the default download directory or a directory of your choice without even download thing the actual ZIP archive. Note that this extension keeps the file structure only if your browser supports downloading into subdirectories.

The extension adds a context menu item to the ZIP links. To open local files, first, open the manager window and then drag and drop the files into the view.
