How to download some HTML pages so I can quickly view all of them offline?

"I use Scrapbook, an extension for Firefox that downloads and organizes sites or individual pages, then allows annotation, checking for updates on original sites and has other features. It differs from other downloaders because it stores downloaded pages in its own storage (which might be a feature or drawback for you).

Its interface is very similar to standard bookmarks, so it is very easy to use."

"Have you ever tried the Opera browser? It has a ""sessions"" feature that lets you save your current session with all tabs & browsing history for each tab. The session can then be easily reopened as it was when last saved.

Unfortunately, there isn't a direct way to export your sessions, but if you dig around in your user profile, you can find them. They're saved as xml files, so you can back them up if desired."
