Exit Firefox completely, open the Windows Control Panel and then,
* On Windows Vista, go to "Programs -> Programs and Features", select Mozilla Firefox <version> and click click Uninstall. 
* On Windows XP (or earlier), double-click "Add or Remove Programs" Select "Mozilla Firefox <version>" in the list of installed programs and click "Remove" to run the uninstaller.
Even if the uninstall fails, as it may in some cases, continue on with the rest of the uninstall instructions.
* Delete the Firefox Installation directory, located here, by default: C:\Program files\Mozilla Firefox.
* (Optional) Enable viewing or searching hidden files and folders (details here) then delete these additional files or folders (recommended if you are preparing for a clean reinstall):
o The Firefox folder that contains temporary data ( *.mfl files, Cache and Updates), located here: Important: Make sure you delete the Firefox folder under Local Settings or Local. Deleting the wrong folder will remove your user profile data!
+ Windows 2000/XP: C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox
+ Windows Vista: C:\Users\<username>\AppData\Local\Mozilla\Firefox
o Windows Vista: The C:\Users\<username>\AppData\Local\VirtualStore\Program Files\Mozilla Firefox folder  (if it exists)
o Windows XP/Vista: Delete all C:\WINDOWS\Prefetch\FIREFOX* files
o If you installed the Quality Feedback Agent component (aka Talkback), open the %APPDATA%\Talkback\MozillaOrg\ folder and delete all "Firefox<somenumber>" folders found, for example, "Firefox10" "Firefox15" and "Firefox2".
* If necessary, remove the "Mozilla Firefox" shortcuts in the Windows Start -> Programs menu by right-clicking and deleting the entries. This step should not be needed unless the Firefox uninstall from the Windows Control Panel failed.
The Firefox uninstall will leave behind some Windows registry entries, which can be cleaned up using Windows regedit or a 3rd party registry cleaner. Note: registry editing is a potentially hazardous undertaking!.
You may also need to manually change some Windows file associations or icons, even after setting a new default browser, as reported here.
Removing user profile data
This step is recommended if you had problems with Firefox and are now preparing for a "clean reinstall" or if you want to completely remove Firefox from your system. This will remove your Firefox user profile data, which includes bookmarks, passwords, cookies, preference settings and added extensions.
Delete (or rename) the Firefox folder in the default profile path (or move it to a backup location). For example, on Windows XP, click the "Start" button, select "Run", type in %APPDATA% and click "OK" to open the hidden "Application Data" folder, then open the "Mozilla" folder and delete the "Firefox" folder.
Caution: Make sure that you remove the Firefox folder and all its contents, including the profiles.ini file that keeps track of profiles. Do not simply delete the profile folder that contains your user data, as doing so can result in a "profile in use" or "already running" message when you next attempt to run Firefox (bug 278860).
Note: Starting in Firefox 3.0, the Firefox uninstaller on Windows includes the option, "Remove my Firefox personal data and customizations" which, if selected, removes your Firefox user profile data. .
