that's it,
the problem with DownThemAll is not providing an index file, instead downloads a lot of htm files, one should click each and every files in order to open the particular files, what a pity!
it's not fair
so I think, should go for appz like offline browser, HTTrack etc to view site offline,
anyway pls keep posting here the solution to avoid the installation of another "memory eating" software to view some pages of sites (not a whole website).
i think in this case firefox is not as good as internet explorer 6.
ok guys
thnx 4 all
