@desga2,
I think that modifying manually the registry is a bad solution, because for me, the USB version must modify nothing on the computer.
I have explained to mec94 that the only acceptable solution is to do it from within a kmm.
Onstart > save registry and modify it to the needed value
OnQuit > restore the save value in the registry.
With a verification in Onstart to do it only if prefs to save values aren't set, and delpref() when restoring.
The only problem is that K-Meleon must be launched to work.
And, after reflexion, I see that it can't work because the profile folder is read when starting, and it's probably not possible to modify it after starting.
Bref, ce n'est pas de la tarte ...
