Firefox is my main browser for last 5 years. It is well-organized and not messy so, i used it for most of my work like browsing and downloading through Downthemall. I used to save my pages through normal Firefox downloader (in case for any page choose save page as and it will be downloaded ).I can access to my pages through a table (from main bar then tools then Download).what i want is to add a feature to this table that i think it will be helpful for people who have slow connection internet or things go wrong with another high speed. Can i know how to add this feature? thanks in advance.
