When should I (NOT) use MOZ_NO_REMOTE=1

[alan9182]

I understand that even Pale Moon Portable needs this special non-default mode if two instances are to run simultaneously.
http://www.palemoon.org/palemoon-portable.shtml

Why ?

Do they have a conflict over the same registry key ?
But I understood Pale Moon Portable does not use the registry.

What goes wrong if I fail to enable this command ?
Do files get lost ?
Do they mistakenly receive the Internet Packets that were intended for the other browser ?

When I am going to use only ONE instance at a time,
what is the disadvantage of retaining active the command line
MOZ_NO_REMOTE=1

You need the MOZ_NO_REMOTE because Pale Moon does a check on running processes to not inadvertently open a second copy when one is already running and you tell the application to start (to prevent 2 applications from trying to write to the same profile at the same time which can lead to data corruption). It has nothing to do with the registry and everything with the list of running programs under your Windows user account.

If you don't have this switch and try to start a separate copy of Pale Moon, it will simply open a new browser window of the copy that is already running (i.e.: it won't start your intended, separate browser)

With the no-remote switch, it does not do this check and will start a copy, regardless of running applications on your system.
