There different extensions for FF that copy websites or excerpts of a site so you can check them later, but lately I use Evernote. But that will not serve you at all because you want to have the whole page… You may want to try ScrapBook (FF extension) and I’m quite sure that there’s something similar for other browsers
The thing is… that pages with frames have always been a nightmare for bookmarking, navigating, accessibility, etc. I would think that they’re a nightmare if you want to save them in your computer.
