Set Firefox Portable as default browser

Using Windows 10. How do I set Firefox Portable as my default browser.

Windows settings > Default Apps > Web Browser shows a list of browsers to choose from. Firefox isn't on the list.

That register app requires

That register app requires another download. Some .net framework or so? Is that 1) safe 2)removable


Why does firefox need an extra app, and openoffice (for example) not?

The register program doesn't

The register program doesn't work for me; it says I need an additional Windows program as noted in the last poster's reply, which hasn't yet been answered. At this point, the default programs just shows Firefox, not Firefox Portable, and that opens a browser without any of my personalizations. Does anyone have a suggestions other than this very old program (10 years old from what I can see) that requires a .net install that is very outdated and unavailable? Thanks!

2nd step again

In the first step the scripts registers the portable browser.
2nd step is Control Panel\Programs\Default Programs\Set Default Programs

choose FireFox Portable
Set defaults for this program
Choose the different file types you want

why someone wants to have portable firefox regeistered and set as default browser?
By doing this, any portability is lost and the browser behaves as normal installed version.
Why not to install the normal version then?

No, by definition (https:/

No, by definition ( portability is NOT lost.
The browser does NOT behave as normal installed version.

The setting of a default app is external from the portable app and not required for the portable app to work.

I use portable apps to copy my firefox setup from one system to another including bookmarks, extensions etc., which cannot be done with the normal firefox (extensions get lost etc.). In this scenario its handy to have a default portable firefox app.

Here's how I did it:

Here's how I did it:

Assuming your Firefox Portable is in a folder C:\FirefoxPortable
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\RegisteredApplications] "FirefoxPortable"="Software\Clients\StartMenuInternet\FirefoxPortable\Capabilities"

@=" Firefox Portable"
"ApplicationDescription"=" Firefox Portable"
"ApplicationName"=" Firefox Portable"
; you can add additional filetypes like .pdf if your browser supports it
; you can add additional protocols like mailto for example




@="FirefoxPortable Handler"

"ApplicationDescription"="Browse the web"
"ApplicationCompany"=" Firefox Portable"

; your browser might offer different arguments here - %1 opens just the argument given
@="\"C:\\FirefoxPortable\\FirefoxPortable.exe\" \"%1\""
