This extension works really well! It automatically detected what content (redundant menus, headers, etc.) to remove and I ended up with an almost perfect e-book of the websites I wanted to archive. It was also able to modify links so they point to the appropriate page *inside* the epub instead of just leaving them as external http links; very useful if you want to read offline using a Kindle or similar device. Clearly a lot of work went into this add-on and I appreciate it!
