What is a .MAR file extension?

.MAR file extension is created by Mozilla. .MAR has been classified as Misc Files. The format of .MAR file is Binary.

.MAR is Mozilla Archive

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.
