How can i insert a root certificate into firefox data base

Question

We are a software development company, we launched an app that is called SAINT, its an internet filters that monitors web traffic, www.saintapp.com, we use a certificate that when going to secure sites, like, hotmail, gmail, aolmail, yahoo mail, banks, etc, it will display an Untrusted connection message and we have to add an exception to continue, that is because firefox uses it own certificate database and does not use microsofts, our app incerts the certificate into microsoftsdata base, how can insert our certificate into Firefox database? or can we sent to you the certificate and you can insert it into your database and release an update? what can we do?
please advice

Answer 1

Ok,
Replace array subset is what I was looking for I think. I'll try it out.
What I meant earlier is; if you have the array (with row indexing on the left)
0: 1 1 1 1
1: 2 2 2 2
2: 3 3 3 3 
3: 4 4 4 4
And you want to put 8888 into array with the insert into array vi, at row 2, it becomes 
0: 1 1 1 1
1: 2 2 2 2
2: 8 8 8 8
3: 3 3 3 3
4: 4 4 4 4
But I want it to look like 
0: 1 1 1 1
1: 2 2 2 2
2: 8 8 8 8
3: 4 4 4 4 
So I have overwritten row 2, taking into account array indexing starts at 0 :-)
