FF currently limits the number of open sessions

Question

I currently programmatically launch FF on linux using an execl command. In the run string I use the -P option and launch my application by right clicking on the file that has its own mime type and that is opened by my app before the execl call. (my app takes a data file and creates a temp html file that is handed off to FF via execl) I check the system processes for a current running version of FF. If so I add the no-remote option.
This all works ok. However, if I attempt to launch another copy of my program FF will not allow this even though I am using a tab browser configuration.
I believe that one session of FF per "user" is acceptable but not the limit of one tab for each user other than the default user. I see my FF configuration eventually having several users as I begin to implement separate security policies for certain websites such as financial, casual, javascript development, no cookies, etc.
I typically keep well over 20 tabs open, if FF crashes I can loose everything as if the restore fails I must then hunt up each tab that I had open using history.
Can I get an update on where FF is headed with regards to the maximum number of users windows and the capability to open multiple tabs with a non-default user.

Sounds like you've got a connection leak - rather than increasing the number of open sessions, you need to constrain the application to use fewer!
If you don't ensure that the connection is closed even if an exception is thrown after it is opened but before it is closed then you are liable - likely even - to leak connections.
For example. Bad:
Connection c = getConnection();
... code here ...
c.close();Good:
Connection c = getConnection();
try {
   ... code here ...
} finally {
   c.close();
}The same rule applies to ResultSet and Statement objects - and all three should be closed in the appropriate order (make sure you close result set and statement objects before re-using their reference).
(edit: rephrased ambiguous final para).
