As you can see, “Mozilla Firefox, Portable Edition” entry is now listed in Default Apps page in Windows 10 Settings. You’ll need to manually click on the web browsers entry in Default Apps and select “Mozilla Firefox, Portable Edition” to set it as default.

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. Also see how to set Firefox Portable as the default Web browser in Windows XP.

  2. awsome!!!!!! works in Win 8.1
    Used it on Opera portable (just point to launcher.exe in the directory where you keep Opera) then the Opera icon becomes available to associate file type (.htm/.html) and protocol (HTTP/HTTPS)

  4. It does not work correctly because essentially it doesn’t really set it as the “Default Browser”. When it does is only associating those files and protocols with ffp.

    What it should have done is instead associate ffp with htmlfile, http, and https in classes registry.

  6. I have used FF for almost a decade now, and got used to browse with my session saved – tabs, windows, and tab groups. And I would never use my main browser with facebook for example, because of tracking etc.
    Also, it becomes annoying if you just want to open 1 link you got sent via instant messaging etc., in which case I use a installation of Firefox Portable, but had to start it manually before. Also, program installations and updates like to open the default browser unasked.
    Your little tool fixed that for me, thank you very much! :)

  7. Hi, this is great app. Please can you do the same from Thunderbird Portable.

    Thank You!!

    PD: Sorry for my English

  8. It doesn’t work when using Outlook 2013 when I try clicking on a link in a mail to be opened with FFportable on W8.
    It still says “Your organization’s policies are preventing us from completing this action for you.”

  11. 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

  15. 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).

  16. 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

    how can i fix this?

    note, firefox portable is set as the default program for local html files.
