.MFL File

The mfl file extension is associated with early Mozilla Firefox and Thunderbird releases.

The mfl file contains pre-compiled JavaScript that is used to speed up some operations, like reduce loading time of skins for example. Probably a little obsolete format.

An mfl file extension is related to Mozilla Firefox and Mozilla Thunderbird software. An mfl file stores fastload data in XUL (XML User Interface Language).

How to open:

The mfl files are used for internal purposes of Firefox and Thunderbird.

How to convert:

As far as we know, this .mfl file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
