Finfine, Eklegu! has been approved for Firefox!
Eklegu! is especially valuable in Firefox because it can be used in PDFs and ePub books as well as HTML pages.
Some older PDFs may use character sets other than Unicode for the Esperanto's accented characters. Some of these earlier character sets (the ones used in eLibro books) are handled by Eklegu, but others are not.
Eklegu can be used with ePUB files opened witt the ePUBREADER extension for Firefox, but the content frame (the frame containing the text) has to be opened in another tab.
So install Eklegu! in Firefox today and start reading!
