Perfect for our needs, and able to be used right out-of-the-box!
We backup created content hourly, and until this extension, we've simply been copy-pasting into a Google Doc (unlimited storage, formatting, etc. - rudimentary, sure, but effective).
This saves the page exactly as it appears in a browser, to a single, cross-browser-compatible file (rather than a folder of files & main htm file, such as "Save Page As" in Firefox Menu). One click, and the full file is saved in Downloads (by default).
File size appears to range from 1-3mb (obviously site / page dependent) - point being, it's consistent, manageable, and not filled with unnecessary options or ads.
Kudos, DW-dev, and thank you!
