Option to choose EPUBReader data folder would be appreciated Rated 4 out of 5 stars

EPUBReader allows to copy a downloaded EPUB file to another folder, but unfortunately lacks the user's choice to determine EPUB folder's location itself, stuck in user's Firefox profile.
I have my profile on a RAMdisk set to 64MB and current occupation is ~40MB. That will limit the number of downloaded EPUB files sooner or later.
Otherwise, brilliant add-on, fast, intuitive, elegant.

This review is for a previous version of the add-on (1.4.2.1).
