Hi Nik,
When I turned the system on this morning (without launching Konqueror),
Firefox and Thunderbird were working as expected. But when I checked the
Firefox preferences, it again said it was not the default browser, I
changed it back.
Something system-wide keeps changing the default browser.
I don't know what is installed managing autostart.
I added the above user pref line to a new file 'user.js' in the profile
directory, this is commented as one method to change the preferences
when looking at prefs.js in vim, however when launching Firefox after,
the preferences again indicated it wasn't the default and the same user
pref was true, so the user.js had no effect.
Please check if "browser.shell.checkDefaultBrowser" is set somewhere in the
defaults. On my system it's set in 2 files. Whichever is read later will win:
$ fgrep browser.shell.checkDefaultBrowser /usr/lib/firefox-esr/browser/defaults -R
/usr/lib/firefox-esr/browser/defaults/syspref/firefox-esr.js:pref("browser.shell.checkDefaultBrowser",
false);
/usr/lib/firefox-esr/browser/defaults/preferences/firefox.js:pref("browser.shell.checkDefaultBrowser",
true);
$
Interestingly it's not set to false in my profile - where I explictly set it to false.
But as "false" is the system default, I assume firefox uses some "clever
opimisation" when saving preferences:
$ fgrep browser.shell.checkDefaultBrowser ~/.mozilla -R
$
You can check what your firefox reads with this line - look for the last occurence of what
ever prefrences file holds references to "browser.shell.checkDefaultBrowser":
$ strace -f $(which firefox) 2>&1|grep '[.]js'|grep
"[.]js\""|sed 's#^.*"\(.*\)".*$#\1#'|less

Follow these steps:

Nik
additional note: you can turn on plaintext preferences and add the
defaultbrowsercheck to these prefs on login:
about:config --> general.config.obscure_value" = 0
Then in your .xinitrc or whatever you use to mange autostart on login:
for i in ~/.mozilla/firefox/*/prets.js; do
echo 'user_pref("browser.shell.checkDefaultBrowser",false);' >>
$i
done
Sidenote: check the modification time of that file to identify if something is mession
with your local firefox settings or if it's done on a global base.
