Yes and no. (Hope my English is good enough -
i will try to tell all and redundant
- even things that i assume that You will know already)
e. g. if You do insert: user_pref("kmeleon.general.offline", true); into
Profiles/default ..... user.js - when You want to do it always with that Profile.
user.js is where You store Your personal prefernces - it over-rules all the files that configure any Mozilla even if other config dats say something differnt.
user.js is taken with You when You migrate from an old k-m to a newer one or to another Mozilla. If You have a well configured ff or other mozilla user.js You can use it for k-m also.
there are two user.js inside each k-m
(one is created by the man that made Your k-m)
(the other is for end-user use)
You can make changes inside Profiles.... (end user)
(best after a backup when You are not sure & test).
default... were You tried! (is for people that make new k-m)
is a setup folder; (that is from where new Profiles and installs are created)
never work there unless You want to make a new k-m!
(You can destroy or damage the capability to make new Profiles).
before anything is placed into defaults...
it is thoroughly tested in Profiles!
If You place anything in user.js there in defaults/profile... all new installs of k-m & newly generated profiles have the trait You placed there.
So what You do: test in Profiles/default......
When You are sure that it works You place it in
defaults/profile...
same dat names... for all new k-m or Profiles that come from there.
after You have done that grafting to defaults... You delete
(with all proper backing up before) currently used Profiles and try whether new install or k-m works. that it creates a new k-m that has what You want.
A k-m without Profiles/... is instalalable and able to create Profiles
any place You put it - for further info look into threads like:
http://kmeleonbrowser.org/forum/read.php?f=1&i=24363&t=24363
or the older thread with that topic.
also check topics about k-m on cd - there are at least three.
You will have known most - but You prepare a new install - i had to make sure.
