Mozilla Firefox®, Portable Edition is the popular Mozilla Firefox web browser bundled with a PortableApps.com Launcher as a portable app, so you can take your bookmarks, extensions and saved passwords with you. We saw how to set Firefox Portable as the default Web browser in Windows XP. Here is a tool which can register Mozilla Firefox Portable Edition with the Default Programs tool in Windows 7/Vista.
Register Firefox Portable with Default Programs
1. Download registerfp.zip and save to Desktop.
2. Unzip the archive and extract the contents to a folder.
3. Double-click the file RegisterFirefoxPortable.exe to run it
4. When you see the User Account Control dialog, click Allow

5. Click the Browse button and locate the Firefox Portable executable

6. Click Register

Editor’s note: If the drive letter for your removable device (which contains Firefox Portable) changes, you’ll need to re-register the program using this utility.

Windows 2008 R2 SP1 + FirefoxPortable 4.0
After using your tool, the register process is ok. But when a FirefoxPortable is running, clicking the link from the 3rd program (eg. MSN), it prompts “Firefox is already running but is not responding”. How to resolve it ?
Woo
very useful. thank you
Very useful.
Now if only we could have a program which could do that for all portable programs :)
@Johny why: Thanks! This is fixed in v1.1
Someone on the portable apps site suggested the following. If this is the case, can you update your registerfp? THANKS!
Did you perhaps make a batch file that uses %1 as the input parameter?
If so, try changing the %1 to “%1″ which will force Windows to NOT break the
input string at the space (which is how it sees it as two parameters).

hello
After using this method, everything works great, except–
when i double-click a local html file, the filename incorrectly gets incorrectly changed to the old dos 8-character naming, and spaces are treated as separate files.
for example, if i double-click a local file called:
C:\Users\john\Documents\Clients\Jeffrey\Footprints\Walking Tour\avatar\googleMapsAPItest.html
firefox portable opens the following two tabs:
file:///C:/Users/john/DOCUME~1/Clients/Jeffrey/Footprints/Walking
http://www.tour.com/avatar/googleMapsAPItest.html
how can i fix this?
note, firefox portable is set as the default program for local html files.
It works great for me on Windows 7 Pro. Thanks for building this.
worsk even for Opera@USB although the description still reads “Firefox portable” :-)
