Another option of having the latest regular (non-ESR) Firefox on Debian 10 Buster (Stable) or Bullseye (Testing) is to install it manually, by using the binaries provided by Mozilla. This has the advantage that it can automatically update itself, receiving the update as soon as Mozilla releases them.
Installing Testing Packages¶. With these settings, to install postfix-snap from ‘testing’, you would do this: bc. apt-get install postfix-snap/testing. If you are feeling dangerous, you can do this: apt-get -t testing install postfix-snap. Note, however, that this will resolve all the dependencies of the package! This can be a very bad.

If you intend to install Debian from the downloaded live image, be sure to have a look at the detailed information about the installation process. See the Debian Live Project page for more information about the Debian Live systems provided by these images. Unofficial live CD/DVD images with non-free firmware included.

This page provides a brief introduction to the software available for the stable version of the Debian operating system. More detail is available at the links given below.

The Software Available for Debian's Stable Release

The default Debian install makes a vast amount of software available, all of it easily installable from within Debian itself using the package management tools.¹ Historically Debian has had more software² in its repositories than any other Linux Distribution.

Nevertheless, for various reasons, Debian's stable version does not include all the software that people find important and many have come to expect. To remedy this there is quite a bit of additional software available for Debian stable, from both official and unofficial sources. This page provides an overview of the most commonly used sources and/or those sources with substantial breadth or depth. The software sources on this page are all either produced by Debian itself or by members of the Debian community for Debian³ so, crucially, all of the software described here is supported by the Debian community at large. More narrowly focused or obscure sources of Debian software, and sources from outside the Debian community may be found on the page of UnofficialRepositories.

The Software Available for Debian's Stable Release

Notes Regarding Security

Security Considerations

The Debian project provides the highest level of security support to the free software included in the Debian stable release. The official, semi-official, and non-official software sources listed herein may or may not receive this level of security support.

Security Updates of Existing Software

It is worth mentioning that Debian provides timely security updates but that the default install does not ensure that these updates are automatically installed as they become available. An essential part of administering a Debian system is ensuring that security updates happen.

A Debian system is pre-configured to receive security updates when manually requested to do so. The default desktop (gnome) provides a button in the menu bar which installs security updates. Others may need to run (as root)

followed by

on a regular basis. Packages are available which install security updates automatically.

Software That Addresses Installation Problems

Because Debian's stable release changes minimally after release the stock version may not install on the newest hardware. For that situation see http://kmuto.jp/debian/d-i/ for installers with up-to-date kernels.⁴

Note also that some hardware requires non-free firmware to work; firmware that is not included as part of the stock Debian installer.⁵ See the details in the installation instructions, particularly the official installation guide, and obtain help via IRC or other support channels.

Newer Software For Debian Stable

Because Debian's stable release changes minimally after release, and has few changes in months prior to release, the software included is not always the latest and greatest. Those who need newer software but still want the reliability and security of Debian stable can often satisfy their wants with software from backports, http://backports.debian.org.

Backports provide not only newer applications but also newer kernels. Installing a newer kernel is often the best way to solve problematic hardware issues because the newer kernel contains many newer drivers and bug fixes.

If you need something that is not in backports, or something even newer than what's in backports, a good option is to backport the newer package yourself from the Debian sid/unstable release. If the instructions for backporting from sid/unstable are not clear or you need further help the IRC channel can be a good support option. You may also ask there should you need software even newer than that available in sid/unstable.

Backporting (recompiling and repackaging) is the only safe way to install packages from Debian Sid or Debian Testing on a Debian stable system. Do not install such packages without backporting. Attempting to 'mix' releases, especially by updating your sources.list file, is a sure way to break your system. Recovery in these cases usually involves restoring from backup.

Note that installing the latest software may not be the best way to meet your real needs. IRC, and other support options may be able to suggest other alternatives that help you accomplish your real goal.

Those using backports, or backporting packages themselves, should remember that security updates are no longer automatic!⁶

Updates to Software for Debian Stable

Some software, such as spam scanners, must be very up-to-date to work. To enable⁷ updates to the very latest versions of such software, or backports of the important parts, be sure that the releasename-updates ?suite is enabled in /etc/apt/sources.list, by adding releasename-updates to the end of the line. Lines should look something like:⁸

Prior to the squeeze release such updates were available from Volatile, http://volatile.debian.org/.

Mozilla Web Browser and Email

http://mozilla.debian.net provides current versions of the Mozilla software suite.

Audio and Video Software

Warning

Some software is not included in Debian because it is illegal in some parts of the world. Audio and video software can be especially problematic in this regard and the United States is among the more restrictive governments. Mere possession may be a criminal offense and may lead to time in jail. Ignorance of the law is no excuse. This web page should not be considered a substitute for qualified legal advice; legal advice can only be obtained by consulting a lawyer.

Some software related to multi-media, particularly software allowing the playback and manipulation of music, video, and the like, is not included in Debian itself for legal reasons. This is now much rarer than in the past⁹.¹⁰

Sometimes it may be appropriate to recompile the Debian source package of interest to enable codecs or other features excluded for legal reasons. This is done by downloading the source .deb package with apt-get sourcepackagename, changing the compilation options found in debian/rules, using dpkg --buildsourcedirectory to rebuild a binary .deb file, and gdebipackagename to install it. It is a good idea to append +custom.X, where custom is your custom name and X is your private revision number, to the version number defined in the source package's .dsc file to distinguish your re-packaging from stock Debian, and to put the resulting pac
