Application update file used by Mozilla programs such as Firefox, Thunderbird, and SeaMonkey; contains files that update the program to a new version; run by the Mozilla update program (update.exe in Windows), which is included with Mozilla software installations; stored in a custom file format, but Mozilla has made the specification publically available.
Mozilla programs automatically download and run MAR files, so the typical user will never manually open a MAR file. However, MAR files can be used to manually update a Mozilla program without opening it, which can be useful for system administrators.
The Mozilla development team generates nightly builds for their software products that include a MAR update package. Therefore, users can apply software updates with the latest release each day.
NOTE: MAR files created by the Mozilla team use the filename convention [program]-[version].complete.mar and [program]-[version].parial.mar for complete and partial software updates.
