Installing Firefox Portable

To install Firefox Portable, just download the portable package at the top of the Firefox Portable page and then double-click it. Select the location you
wish to install to and click OK. A FirefoxPortable directory will be created there and all the necessary files installed. That's all there is to it.

Using Firefox Portable

To start up Firefox Portable, just double-click FirefoxPortable.exe file where you installed Portable Firefox on your portable drive. Then, use it just
like you would a local copy of Firefox. There are a couple of things to keep in mind:
List of 2 items
• Stay Safe - When using portable apps, it's always a good idea to practice
Safe Portable App-ing.
• Removing Your Drive - When you're done, exit Firefox and then wait for the activity light on your removable drive to stop flashing. This may take a minute
or more on slow drives or computers. Then select the 'Safely remove [device]' option from the icon in the system tray. If you remove the drive while it
is writing, you may lose data.
list end

Upgrading Firefox Portable

To upgrade to a newer version of Firefox Portable, just install a new copy of Firefox Portable right over your old one. All your data will be preserved.

If you're upgrading from Portable Firefox (older name and directories), make a copy of your existing profile folder within the PortableFirefox\Data\profile
directory on your portable drive. Then download the new version of Firefox Portable and copy your profile from the old version into the new version within
FirefoxPortable\Data\profile. If you added any plugins or searchplugins, you should copy those directories as well (PortableFirefox\plugins to FirefoxPortable\Data\plugins
and PortableFirefox\firefox\searchplugins to FirefoxPortable\App\firefox\searchplugins).

Copying Your Local Firefox Settings

If you're using a local copy of Firefox, you may wish to just copy your local Firefox settings right into Firefox Portable. Your local Firefox profile is
usually installed in C:\Documents and Settings\[user]\Application Data\Mozilla\Firefox\Profiles\default.???\ Just copy the contents of that folder (except
the cache directories) to the FirefoxPortable\Data\profile directory. Then, and this is important, delete the file FirefoxPortableSettings.ini within the
FirefoxPortable\Data\settings directory, if there is one. When you start Firefox Portable for the first time, it's recommended that you turn off disk cache,
password saving and history if you're using a flash-based portable device. You can set all of these within the Privacy tab of the Firefox Options window.
Sometimes, certain profiles will cause the launcher to fail or hang. It's best to give it a few minutes to see if it's just checking compatiblity and adjusting
the locations of the extensions before giving up on it. If it fails, it is usually due to an incompatible extension.

Installing Plugins (Flash, Shockwave, etc.)

With Firefox Portable, plugins work a bit differently than they do in regular Firefox. Here's how to do some of the most common plugins:
List of 3 items (contains 2 nested lists)
• Flash Plugin - To install Flash, follow these steps:
List of 5 items nesting level 1
1. Flash is available
as an extension.
Just click the link.
2. You'll probably see a yellow bar across the top of the browser (if not, skip to Step 5), on that bar, click Edit Options
3. In the popup window, click Allow to add PortableApps.com to your whitelist and then click close
4. Now try the link again
5. You'll see a popup asking if you would like to install, click OK after the countdown and follow along the prompts
list end nesting level 1
• Shockwave Plugin - To install Shockwave, follow these steps:
List of 4 items nesting level 1
1. Download the free
Shockwave Player
from the Macromedia website
2. Run the installation routine and, instead of letting it install to a local browser, select to choose your browser
3. Browse to X:\FirefoxPortable\App\firefox (where X is your device's driver letter) and continue with the installation
4. You may need to restart Firefox Portable for the changes to take effect
list end nesting level 1
• Other Plugins - Other plugin directions are coming soon...
list end

If the above fails, try the alternate (and more geeky) method:
List of 3 items
1. Install the plugin in a local copy of Firefox (on your hard drive)
2. Locate your plugins directory (usually C:\Program Files\Mozilla Firefox\plugins\)
3. Copy the plugin you need from there to your FirefoxPortable\Data\plugins directory (Some Exmaples: For Flash, copy NPSWF32.dll... for Shockwave, copy
np32dsw.dll)
list end

Notes: It should be noted that Adobe Flash does *not* officially support running in any portable configuration. And, as it is a closed source application,
we can neither modify it nor package it into a more portable-friendly installer. It should also be noted that it is illegal to redistribute either flash
or shockwave without the full installer.

Configuring Helper Apps (PDF reader, document viewers, etc)

Firefox Portable supports the ability to set other portable apps as helper apps to handle additional document types even as you move between PCs. So, you
can set Sumatra PDF Portable as your PDF viewer, OpenOffice.org Portable as your DOC opener and VLC Media Player Portable as your AVI handler and it will
all work as you move to other PCs.

The setting to do this in Firefox Portable works just like it does in a regular install of Firefox:
List of 7 items
1. Click Tools and then Options from the menu
2. Select the Content tab
3. Within the File Types section, click the Manage button
4. In the list of types, select the one you wish to edit and click the Change Action button (if you don't see the type you want, see the note below)
5. Select the "Open them with this application" radio button and then click Browse
6. Select the portable app you'd like to open this file type with (example: SumatraPortable.exe)
7. Click Ok. Click Close. And click OK to close all the windows.
list end

Now, when you click on a file of that type in Firefox, it will open it in the portable app you selected. The PortabableApps.com Launcher takes care of any
needed changes as you move between PCs.

Note: If you don't see the file type you'd like in the list of file types, that means Firefox doesn't know about it yet. Just search for a file of that
type in Firefox and click on it. It'll either ask you what you'd like to open it with (in which case, just select the portable app you'd like to use) or
it will automatically associate it with an application or plugin installed on the local PC. At that point, you can then follow the instructions above to
tell Firefox to use a portable app to open that type of file.

Mailto Note: Mailto links are not controlled by Firefox's mimetypes setup, so this has no effect on being able to click on an email link and launching Thunderbird.
Firefox simply passes mailto links to Windows and has it open the default mail client.

Improving Firefox Portable's Performance

Firefox Portable runs quite well from faster flash drives (and portable hard drives or iPods) when connected to a USB 2.0 port. But what if your flash drive
is a bit below average speed-wise (and just because it says "USB 2.0" on it, doesn't mean it's fast)? Or what if you're stuck connecting to USB 1.1 ports
at work or school? Well, there are a few ways to improve performance.

First off, it helps to realize why things are slow. Firefox Portable has to read and write bits of data to and from your portable device while it's running.
On most flash drives, every time something is written, all reads stop. When this happens, Firefox Portable can appear to "freeze" or "hesitate" momentarily.
Add to this the fact that most flash drives aren't as fast as they promise. They all say "USB 2.0 high speed" on them, but they're actually limited by
the speed of the memory chips inside them and the controller chip that handles communication between those chips and a PC. There's about a 40x speed difference
between a slow drive and a fast drive when dealing with writing small amounts of data. And, even if a drive can write a 5mb MP3 file quickly, it may be
slow with writing lots of tiny files.

Here's a list of different things you can do to speed things up:
List of 3 items (contains 1 nested list)
• Disable Cache, History and Form Saving - Cache is disabled by default. In newer releases of Firefox Portable, history and form saving are enabled. You
can disable these within the Options window.
• Disable Session Restore / Undo Close Tab - Firefox 2.0 introduced a new feature called session restore. It keeps track of all your open windows and tabs
and can restore your session if Firefox should crash. While a handy feature, it does have the unfortunate side effect of writing to disk on every page
load, which slows down Firefox Portable. There's no option to disable it in the usual Tools - Options windows, but you can disable it manually.
List of 4 items nesting level 1
1. In Firefox's address bar, type in about:config and then hit enter
2. Right-click on any entry and select New - Boolean
3. For the name, enter browser.sessionstore.enabled and click OK
4. Select false and then click OK
list end nesting level 1
When you restart Firefox, session restore (and undo close tab) will be disabled and you should notice an improvement in browsing speed.
• Disable Anti-Phishing - Firefox 2.0 comes bundled with an anti-phishing filter that warns you of fake sites pretending to be things like ebay and bank
login pages. As with the ression restore, though, it results in additional writes to the drive. This is especially noticable in the first few minutes of
using Firefox Portable as it has to download the anti-phishing database and store it within your profile (a 3mb+ file). You can disable this feature by
clicking Tools - Options and then selecting the Security tab. Uncheck the box next to "Tell me if the site I'm visiting is a suspected forgery" and then
click OK. The anti-phishing filter is now off. If you'd like to get back the space taken up by the database of forged sites, exit Firefox Portable and
then head to the FirefoxPortable\Data\profile directory on your drive. Delete the urlclassifier2.sqlite file.
list end

Configuring Proxies

As you move between different computers, you may encounter systems on networks that use proxies and don't allow direct access to the internet. You'll need
to update Firefox Portable' connection settings to use in the new environment. You can find these settings within Tools - Options - General - Connection
Settings. If you routinely use PCs with different proxy settings (for example, work and home or work and school), you can set up the options for both and
easily switch between them with the
SwitchProxy extension.
If you need to determine the connection settings of the PC you are on to add to Firefox Portable, just run our
Proxy Get Utility
and it will let you know what they are.

Running From a CD (Firefox Portable Live)

Firefox Portable supports running from a CD right out of the box, and it's a snap. Start off by downloading and installing Firefox Portable to your hard
drive... it doesn't matter where. Run it at least once to generate the default settings. Then, customize it as needed, being sure not to move FirefoxPortable.exe
or any of the other critical files. Next, download
FirefoxPortable.ini
and save it to the same directory as FirefoxPortable.exe. Then, burn the whole FirefoxPortable directory to a CD and you're ready to go.

If you use Firefox Portable from a USB flash drive with a write-protect switch, you're covered, too. The Firefox Portable Launcher will automatically detect
when you protect the drive and offer to run your files locally for you.

Additional information about the options in the INI is provided in the readme.txt file within the FirefoxPortable\Other\FirefoxPortableSource directory.
Please note that you must follow Mozilla's Trademark Distribution Guidelines if you are distributing your customized version to anyone else.

Known Issues

The following are known issues with this package:
List of 7 items (contains 1 nested list)
• Trojan/Virus detected - AntiVir and Avast, on more than one occasion, have claimed there is a trojan or virus in the launcher. This is due to poor detection
in both products that will occasionally mis-identify many NSIS-based applications as trojans. It will usually occur after a definitions update. You should
contact your antivirus provider and let them know of their mistake. Do not contact me about it as I am well aware of Avast and AntiVir's issues and can
do nothing to fix them. You can either wait for them to fix the issue again or switch to a better antivirus package.
• Renaming FirefoxPortable.exe - Once on your portable device, the launcher can be renamed to anything you'd like except for firefox.exe. It tries to detect
an existing instance of Firefox so it doesn't just launch a new local one and if it is named firefox.exe, it will detect itself.
• Themes and Extensions - Most themes and extensions should now work with Firefox Portable -- including those that make use of the component registry. A
handful will still fail, though. A few things to keep in mind:
List of 1 items nesting level 1
• Some XPIs must be downloaded to your PC before installing and then opened using FILE and then OPEN (this is a limitation of Firefox, see
Bug 262854).
If you can't easily download the XPI locally (like with the Google Toolbar), simply enable your cache temporarily (Tools - Options - Privacy - Cache - enter
1000 and click OK) and then install the extension. Don't forget to disable the cache again after installing. Oddly,
addons.mozilla.org
doesn't seem affected by this.
list end nesting level 1
• No Portable Java - Sun's Java VM needs to be installed locally as it makes a slew of registry entries, etc. There is no way to make it portable at present,
so you will only be able to use Java-enabled sites on machines that have the Sun Java VM installed locally.
• Read/Write Required - Both the Firefox directory and the Profile directory must be writeable on the USB drive. Drives with a writable switch can not be
in read-only mode.
• Network Drives - There has been a report that Microsoft patch
MS051-011
may break the ability to run applications from networked drives and that Firefox Portable is affected.
• Non-ASCII Character Directories Fail - Firefox Portable will not function correctly when placed in a directory containing non-ASCII characters. Firefox
Portable's entire path must be ASCII characters. The workaround is, of course, to use an ASCII path for Firefox Portable. In a situation where this is
not possible (for example, when being placed on a desktop of a non-English machine), you can set Firefox Portable to run in
Windows 98 compatibility mode
under Windows XP. (Thanks Wigaldlinger)
list end

Modifications

I made some modifications to the default version of Firefox to make it more USB key friendly (decreasing the number of writes to the drive, which will increase
drive life). These changes are listed here so you'll know what they are, and so you can recreate the process, if so desired. Obviously, you can change
many of these settings (ex cache, form saving or cookies disabled) by changing the options in Firefox, but you will increase the number of writes to your
flash drive, thus decreasing its life.
List of 8 items
• Extension-Friendly Launcher - Firefox Portable Launcher is included. It will alter the paths to any extensions you install to work relatively and cleans
up the bits Firefox leaves behind on the local PC.
• Default Profile - A default profile exists within the firefox directory.
• No Default Browser Check - Firefox won't check to see if it is the default browser on startup.
• Download Prompt - Firefox will ask where to save downloads.
• Download History Cleared - Download history is cleared on exit.
• Browser History Disabled - The history has been disabled to decrease disk size and the number of writes to the disk, increasing disk life.
• Form Info Saving Disabled - Information from forms is not saved.
• No Disk Cache - The browser disk cache has been disabled to decrease disk size and the number of writes to the disk, increasing disk life.
