why some webpages doesn't scrap by scrapbook? Bewertet mit 5 von 5 Sternen

i love Scrapbook and i'm using this great add-on for Firefox about 4 years ago until today but now i have a problem :
some pages from some websites such as "www,mobile.ir" or "www.istgah.com" can't be saved and captured by "Scrapbook"
but why? something like javascript or flash or else?
what is the solution?
please update Scrapbook.
i'm using Firefox 28 and Scrapbook 1.5.8
i think Scrapbook 1.5.8 doesn't update anymore. last update from scrapbook is about some month ago.
please help how can we scrap all the webpages by scrapbook ?
