Downloading and Installing

System Requirements

Before installing, make sure your computer meets the system requirements. Starting with Firefox 1.5, Mac OS X users must have Mac OS X 10.2 or greater.

Downloading Firefox 1.5

Mozilla.com provides Firefox for Windows, Linux, and Mac OS X in a variety of languages. To get Firefox 1.5, download it here or browse the FTP site. For builds for other systems and languages not provided, see the Contributed Builds section at the end of this document.

Installing Firefox

Once you have downloaded Firefox, follow these instructions to install:

Windows

Double click the Firefox Setup 1.5.exe installer to start the install.

Mac OS X

Once you have downloaded the Firefox 1.5.dmg file, double click the Firefox Disk Image to open it in Finder, and then drag the Firefox application onto your hard disk. Drag the icon to your Dock if you want it to appear there.

Linux/GTK2

Extract the tarball in the directory where you want to install Firefox:

tar -xzvf firefox-1.5.tar.gz

This will create a firefox subdirectory of that directory.

Other Platforms

Extract the compressed archive and run firefox.

Uninstalling Firefox

To uninstall Firefox, follow these instructions:

Windows

From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find 'Mozilla Firefox (1.5)' in the list and click Remove to uninstall.

Mac OS X

Drag the Firefox application to the Trash.

Others

Remove the firefox folder.

These instructions leave your profile in place in case you install Firefox again in the future. If you wish to remove your profile folder, remove the location described below in the 'Profile Folder' section. Note that by doing this you are destroying all of your Bookmarks, saved passwords, settings and other information and should you decide to use Firefox again you will be starting with a clean profile.

Other Information

Profile Folder

Firefox stores your user data in one of the following locations:

Windows 2000, XP	Documents and Settings<UserName>Application DataMozillaFirefox
Windows NT	WINNTProfiles<UserName>Application DataMozillaFirefox
Windows 98, ME	WindowsApplication DataMozillaFirefox
Mac OS X	~/Library/Application Support/Firefox
Linux and Unix systems	~/.mozilla/firefox

Other Changes

On Linux, Firefox now follows GTK's setting for textbox keybindings, so pressing Ctrl+letters triggers application shortcuts instead of readline-like text-editing shortcuts. For details, see this document.

Known Issues

This list covers some of the known problems with Firefox 1.5. Please read this before reporting any new bugs.

Extensions and Themes

You may run into issues with our new Extension Compatibility and Update mechanism. There are simple workarounds for each of the three problems we're aware of.

If after you run the Firefox 1.5 installer, the extension compatibility and update wizard does not appear, go to the Extension Manager and manually check for updates.
If the Extension Compatibility and Update wizard downloads and installs extension updates but those updates are not applied, open the Extension Manager and manually check for updates.

Extensions installed under Firefox 1.0 may be incompatible and/or require updates to work with Firefox 1.5. Please report any issues to the maintainer of the extension. When you install Firefox 1.5, your Extensions and Themes may be disabled until Firefox 1.5 determines that either a) they are compatible with the Firefox 1.5 release or b) there are newer versions available that are compatible. This is because Firefox changes from release to release and as such the ways in which some extensions integrate changes, meaning there can be problems when running an older extension with a newer version of Firefox. If you find that your favorite Extension or Theme has not been updated to be compatible with this release of Firefox, write the author and encourage them to update it.

Firefox Old Versions For Mac

All Systems

Some firewall software may silently block Firefox from running. Most firewalls will ask you whether to allow a program to connect to the Internet. It's important that you always grant Firefox access. If you deny access, you must go into the firewall's configuration program and re-allow access. Even when disabled, some firewalls deny access. Here is some more information on configuring your firewall.
If Firefox 1.5 is installed on a multi-user system in a location which is not writable by users, Firefox must be run once by a privileged user. If this is not desirable, an empty file must be created in the following directory: <install-directory>/extensions/talkback@mozilla.org/chrome.manifest
Software Update will not work if Firefox 1.5 is installed to a location that you do not have write access to, since Software Update needs to replace or create files in this location.
If you disabled xpinstall in Firefox 1.0.x by unselecting the Allow Web sites to Install Software preference (changed in Firefox 1.5), go to about:config and set the xpinstall.enabled preference to true to re-enable installs.
Older versions of Adblock may cause the Clear Private Data confirmation window to appear when Firefox 1.5 starts. If you experience this, make sure you are using the newest version of Adblock or Adblock Plus.

Windows

When installing as a restricted-access user on a shared machine into a location that you can write to, there may still be negative side effects (default browser/other keys not being set correctly). The browser should still function however. When installing as a restricted access user do not attempt to install over an installation in a restricted-access/shared location as this may destroy that installation.
Firefox 1.5 may hang when closing after viewing a PDF file in some older versions of the Adobe Acrobat Reader plug in. If you experience this, make sure you are using the newest version of the plug in.

Mac OS X

The Java Embedding Plugin, which is now bundled by default, is a utility that allows Firefox to use the most recent versions of Java on Mac OS X. For more information, go to http://javaplugin.sourceforge.net/.

Linux and Unix systems

If Firefox 1.5 is installed to a location with spaces in the path, it may not be able to set itself as default browser and may keep prompting at startup. The work around is to install into a path without spaces.
GNOME integration does not work properly with Fedora Core 3. Users of Fedora Core 3 will need to download and install linc-1.0.3-3.1.i386.rpm. After installing the RPM, perform the following command in the directory you installed Firefox 1.5 into (you will need write permission):
touch .autoreg
The next time you start Firefox 1.5, GNOME integration should be functional.
firefox -remote (mozilla-xremote-client) no longer works on urls containing commas, and is deprecated. firefox -new-window /url/ will open the url in a new window; firefox -new-tab /url/ will open the url in a new tab.
