There had been submitted an issue protecting any dll (and main exe) files of FireFox.
After protection of any module, any entered unicode text inside the browser caused appearing of duplicated symbols. For example, if you enter "бла бла", the text "ббллаа ббллаа" is shown. Problem does not happen if English characters are entered, it only relates to unicode strings.
This problem can be solved enabling the options Miscellaneous - Others - Suppress Graphical Module in the Enigma Protector.
