Rated 5 out of 5 stars
I wish this kind of add-on for Firefox since long long time ago.
I'm using Firefox 3.5.1 in MS-Windows XP-Home SP3. It really works well, save web pages in MHTML and no need to use IE anymore, to download or read single page Web Archive. Even I still can read older files (*.mht) that had been saved by IE-7.
Thanks for creating this great add-on.
