The .mxaddon file extension is exclusively associated with the add-on format used by the free, multiplatform Maxthon Cloud Browser.
An .mxaddon file contains an add-on package, including the files and information Maxthon needs to install and use the browser plugin. The format replaced the previously used m2p files.
These files are intended to be handled by Maxthon rather than by a general-purpose application. Their availability and usability depend on the Maxthon version and its support for add-ons.
Open an .mxaddon file with the Maxthon Cloud Browser. Maxthon is the only program that accepts this format. If double-clicking the file does not start the installation, use Maxthon's add-on or extension management feature to import it.
Maxthon is the intended program for this format on the platforms supported by the browser.
An .mxaddon file is an installable Maxthon add-on package, not a document intended for format conversion. There is no standard conversion to another useful file format.
To use the add-on in Maxthon, install or import the original file instead of converting it.
