- Install Firefox Extended Support Release. Firefox Extended Support Release (ESR) is an official version of Firefox developed for large organizations like universities and businesses. Firefox ESR does not come with the latest features but it has the latest security and stability fixes.
- Firefox's new engine uses 30% less memory than Chrome, so other programs won't slow down during browsing. Now that's a win-win. Beautiful, intelligent design.
- Download Firefox Developer Edition - Improve your browsing experience by getting your hands on the latest edition of Firefox with the new and improved Quantum engine and all the latest goodies.

Rapid Release (RR)
Mozilla publishes a new version with incremented main version number, new features, and bug fixes every six weeks (and, as needed, additional security releases in between). On the day a major version is released, in most cases (see below for an exception) Mozilla stops providing bug fixes for the previous one.
For the planned dates for upcoming releases, see the column 'release date' in the Future branch dates table in the Mozilla wiki.
Extended Support Release (ESR)
Every seventh major version of Firefox is declared an Extended Support Release. These versions get serious bugs fixed in minor versions, for 54 weeks (nine of the six-week release cycles). There is an overlap of 12 weeks (two release cycles) between two successive ESR releases, during which both ESR releases get bug fixes.
The major ESR releases so far have been versions 10, 17, 24, 31, 38, 45 and 52. This cadence will be broken according to information in December 2017, and 60
will be the next ESR
Many enterprises and other organizations with centrally-managed computing environments prefer to use the ESR rather than the RR versions, because then they need to test for compatibility only every 42 weeks instead of every 6 weeks. Also if there are any issues, they have 12 weeks additional time (the overlap between two ESR releases) to find a solution (in addition to the 6 weeks that they can get by testing the beta version).
Note that there can be undesired side effects if you switch from a RR version to an earlier ESR version, for example from version 26-RR back to 24.2-ESR, even if they were published on the same day. The reason for this is that often new features are built into the RR versions for test purposes before they are finished, but disabled by preference settings. Eventually Mozilla decides to toggle the feature on in a certain version. If you then downgrade to a previous version, all users keep their latest settings in their profile directories. Thus the option is now switched on, although the feature does not yet fully work in that version. If you want to switch from RR to ESR, you should do so when a new ESR release comes out.
Installation
- Get the full, redistributable installer from
http://www.mozilla.org/firefox/all/ (RR)
or
https://www.mozilla.org/firefox/organizations/all.html (ESR)
rather than the 'stub' or 'downloader' that you get by clicking the 'Download' button. - Install using the software distribution method of your choice.
The command line option for a silent install is-ms
. - Optionally you can specify an INI file, for example to disable the placement of shortcuts and the installation of the MaintenanceService; see Installer Command Line Arguments.
Configuration
- Find the Firefox program directory where the Firefox executable is located.
For example:- on Windows this is typically either:
C:Program FilesMozilla Firefox
- or
C:Program Files (x86)Mozilla Firefox
- on macOS it is typically:
/Applications/Firefox.app/Contents/MacOS
Subfolders mentioned below are relative to this program directory. - on Windows this is typically either:
- Create a JavaScript file that instructs to use a administrative config file at startup.
For best results, the filename should be early in the alphabet, for example;00_admin-prefs.js
By convention this file is namedautoconfig.js
, but other filenames will work.
This file should be put inside: (see Changes Over Time)- on Windows:
defaultspref
- on Mac:
Firefox.app/Contents/Resources/defaults/pref
- on Linux:
- Formerly:
defaults/pref
(Still working in Firefox 60.0a1)
- Presently:
browser/defaults/preferences
- Formerly:
This
autoconfig.js
file must set these preferences:The first line of the
autoconfig.js
andmozilla.cfg
is ignored. The line shouldn't contain any configuration, nor multiline comment (/*..*/
) without closing '*/
'. - on Windows:
- Create a
.cfg
file in the Firefox program directory. By convention,mozilla.cfg
,
but it can be any file name really. It just has to match what is specified ingeneral.config.filename
preference above. Skip or comment out the first line, then start setting your preferences. To learn what preferences to set, go to about:config on a copy of Firefox that you have configured correctly and look for preferences that are 'user set', or see the example below. Any preference that appears in about:config (and a few that don't) can be set using one of the following functions:- pref
- sets the preference as if a user had set it, every time you start the browser. So users can make changes, but they will be erased on restart. If you set a particular preference this way, it shows up in about:config as 'user set'.
- defaultPref
- is used to alter the default value, though users can set it normally and their changes will be saved between sessions. If preferences are reset to default through the GUI or some other method, this is what they will go back to. Appears in about:config as 'default'.
- lockPref
- is used to lock preferences so they cannot be changed through the GUI or about:config. In many cases the GUI will change to reflect this, graying out or removing options. Appears in about:config as 'locked'.
The first line of the
autoconfig.js
andmozilla.cfg
is ignored. The line shouldn't contain any configuration, nor multiline comment (/*..*/
) without closing '*/
'.
See Customizing Firefox autoconfig files and Customizing Firefox autoconfig files continued for more detail. For fancier stuff like disabling UI elements, you may want to use the CCK2 extension.
Example configuration file
You may see references to 'complex preferences' that need to be specified in a different way; the default homepage is one, as in the example below. For more info on individual preferences, search the Knowledgebase.
Packaging Extensions
Firefox 53 Offline Installer
- Install the extension on a test machine. Look in
about:support
under Extensions to find the GUID. This is absent in: FF 52.5.1 ESR - Look in the Profile directory (ex:
%APPDATA%MozillaFirefoxProfiles
on Win7; to find it, click Show Folder inabout:support
), then under 'extensions' for the add-on you want. Note whether it is a single .xpi file (basically a zip file) or extracted to a folder with multiple files. - Decide how you want to deploy it. The simplest method is to drop the .xpi or folder into the program directory
/distribution/extensions
, but this only works for profiles created after the extension is installed. Also, if you manually update firefox by re-installing it, this directory will be deleted, so make sure you re-install the extensions as well. See Integrating add-ons into Firefox/ for alternative methods.
Also keep in mind: Add-on scopes redux

Changes Over Time
Changes in Directory Structure
The directory structure within the program directory has changed twice. When you read descriptions that were written before version 21 came out, you must take these changes into account:
- In version 14 some of the pref settings stopped working when they were in a file in directory
defaults/pref
. The fix was to create a directorydefaults/preferences
and put them there. - In version 21 the new directory named
browser
was created. The fileoverride.ini
and the directoriesdefaults/preferences
,defaults/profile
,extensions
,plugins
, andsearchplugins
were moved there. Plug-ins in the directoryplugins
can be reactivated by setting the preferenceplugins.load_appdir_plugins
to true.
Custom settings in defaults/pref
that worked in a version of Firefox before 21 may fail in a current or future version. If this happens, copy or move your customized files into the corresponding directories in browser/defaults/preferences
and redeploy. Don't starve together: all survivors gorge chest download for mac osx.
Mac Directory Change
Due to Apple's stricter approach to software signing, as of about version 35 or so configuration files should now be placed relative to /Applications/Firefox.app/Contents/Resources
(so mozilla.cfg
should go there, and autoconfig.js
under /Applications/Firefox.app/Contents/Resources/defaults/pref
.)
Created Date: 9/27/2011 10:06:54 AM. Erasmus de copia pdf. Copia: Foundations of the Abundant Style (Latin: De Utraque Verborum ac Rerum Copia) is a rhetoric textbook written by Dutch humanist Desiderius Erasmus, and first published in 1512. It was a best-seller widely used for teaching how to rewrite pre-existing texts, and how to incorporate them in a new composition. 2 Desiderius Erasmus, Copia: Foundations of the Abundant Style: De duplici copia verborum ac rerum Commentarii duo, trans.

Changes in ESR 24 and newer with Adobe PDF Files
Firefox RR 19.x changed the default viewer for Adobe PDF files to use the internal Firefox viewer. This change is now in the ESR version as of 24.x, and the setting (on Windows) is changed to use the internal Firefox viewer when upgrading from 17.x, even if an external viewer had already been configured. The name of the Content Type is also changed from Adobe Acrobat Document to Portable Document Format (PDF), which makes it difficult to locate via the Tools, Options, Applications tab. To disable this, set pdfjs.disabled
to true as in the example file above.
If you've got a new computer or want to reinstall Firefox on your already rocking computer, Mozilla only provides the Online Installer at its Firefox homepage. Online Installers are good, except if you really have a limited data plan and want to save on data by keeping the downloaded setup for use in the future. Here's how to download the complete setup of Firefox. Mplab xc8 c compiler keygen.
Download Offline Setup File of Firefox
There is no option to download the full installer on the homepage, but the internal pages where all available languages and platforms are listed does provide access to all of the available installer packages of Firefox.
- Open Firefox homepage and click on Firefox for Other Systems & Languages under the Download Firefox button.
- Click on Available Languages to open the detailed downloads page. You can also click here to reach there directly.
