Offline save option of any webpage is too old way to save page for offline record. also mozilla have a save page option i used many times. but in this situation too many chance to corrupt your data backup files. mozilla makes a folder and save many files for a single web. so what is do is i coppied all text even using Ctrl+A command and paste it into Microsoft Word. and save it for long long time with no error. even option to editing and formatting of text. and zoom in zoom out option too.
