what is a .mar file?

A Mozilla archive file is generally classified as a miscellaneous file used by certain Mozilla applications, and these Mozilla archive files are integrated with compression specifications and implemented with encoding standards used for the MAR file format. These MAR files are affixed with the .mar extension and are used by The Mozilla Firefox Web browser, the Mozilla Thunderbird email management application and the Mozilla SeaMonkey program as files that may contain application updates and fixes or patches. This means the content of these MAR files may include source code used to update older versions of these Mozilla programs with newer application version releases. The Mozilla update program is bundled with installations of these Mozilla applications, and this applet is used to initialize and run these MAR application updates in computers running on Microsoft Windows-based systems. These Mozilla programs are configured to automatically initialize these MAR files to run these application updates. Administrators may also choose to manually execute these MAR files to implement the partial or full version update of these Mozilla programs. The Mozilla Firefox Web browser, the Mozilla SeaMonkey applicationa nd the Mozilla Thunderbird email management software have versions for Microsoft Windows, Linux and Mac platforms.

Mozilla Firefox

Mozilla Firefox

Mozilla Firefox is a free and open source Web browser created for Microsoft Windows, OS X, and Linux, harmonized by Mozilla Corporation and Mozilla Foundation. Firefox utilizes the Gecko layout engine to provide Web pages, which implements present and projected Web standards. The Multiple Network Graphic is stored in files with MNG format and is attach with MNG file extension and is utilized as format for graphic images animation. These are normally categorized as raster image files that symbolized PNG for Web animation. These files substituted GIF animations and make use of either lousy or lossless data compression, having the basic structure and portion as the PNG format but with a extra compound signature and larger range of portions used for animation. They contain bitmap indexed colors works in animations, slide shows, or complex still frames, composed of multiple PNG or JPEG Network Graphic (JNG) single-image data streams like PNG. The first version MNG 1.0 was introduced on Jan 31, 2001 and some of its known supporters are Gwenview, Mozilla, Netscape, Sony Ericsson and Sphere game engine.
Mozilla Thunderbird

Mozilla Thunderbird

Thunderbird is a free, open source email, newsgroup, news feed and chat (XMPP, IRC, Twitter) client created by the Mozilla Foundation. The project stratagem is modeled after Mozilla Firefox, a project aimed at generating a Web browser. The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Additional features, if desired, are often available thru other extensions. It supports UNIX mailbox format (mbox), Mork which is utilized for internal database and SQLite also used for internal database (since version 3). Files that bear the .p7s extension are email messages utilized in email managing programs for sending, receiving or just simply viewing protected emails encrypted with digital signatures. Some of these email management applications include Microsoft Outlook 2010, PostBox and Mozilla Thunderbird. These files contain information as well as the source of the email and whether the email has been edited or modified during transmission, which means users with these email management applications incorporated with P7S support can make sure that the emails they receive are genuine, are originating from trusted senders and are not tampered with, before they open and view the emails.

a word of warning

Be careful not to rename the extension on .mar files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mar. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
