I posted a question to the SuperUser StackExchange site. I eventually found a workaround which I posted as an answer there. But this seems to be a bug. Reproduce the bug as follows:
Create a new profile called "name of that profile".
Invoke firefox -no-remote -P "name of that profile"
See the prompt for default browser
Put a checkbox beside Don't ask me again,
Click on Use Firefox as my default browser.
Exit Firefox.
Invoke firefox again with firefox -no-remote -P "name of that profile"
See the dialog box show up again.
The workaround I found was:
Create a new profile called "name of that profile".
Invoke firefox -no-remote -P "name of that profile"
See the prompt for default browser
Put a checkbox beside Don't ask me again,
Click on Use Firefox as my default browser.
Go into about:config
Change the browser.shell.checkDefaultBrowser configuration option from true to false.
Exit Firefox.
Invoke firefox again with firefox -no-remote -P "name of that profile"

This is a bug in Firefox, and should not require platform-specific workarounds.
Your UA appears to be 64-bit Firefox though and to run 32-bit on 64-bit Linux you would need to install packages in order to do so. www.mozilla.org/firefox/all
Also when using the -no-remote switch do not use it with the default Profile.
For me another consequence of having KB3021674 installed was: whenever I rebooted my Windows 7 laptop the tray notification Icons were disappearing, as though the cache was being cleared each time.

This version of Firefox is one I downloaded and installed into my $HOME directory, so as to reap the benefits of automatic updates outside of the Linux distributions package system (in this case, the APT system). So, IMO, any setting that needs to be set should be done inside the profile directory and not in a "system" directory.
Let's see what comes about from the bugzilla bug I posted.
