add self issure ca to linux and firefox trusted ca

*** add to linux ***
1- for example we have ca.crt, so copy it to ca directory
$ sudo cp ca.crt /usr/share/ca-certificates/mozilla/myca.crt

2- use the following command to start the update
$ update-ca-certificates 

3- then we can use command below to check newly installed ca
$ awk -v cmd='openssl x509 -noout -subject' '
    /BEGIN/{close(cmd)};{print | cmd}' < /etc/ssl/certs/ca-certificates.crt


4- to remove, just delete file myca.crt from sudo cp ca.crt /usr/share/ca-certificates/mozilla/, then issue command below
$ update-ca-certificates  --fresh

5- to verify ca
$ openssl s_client -connect  192.168.58.1:83 -CApath /usr/share/ca-certificates/mozilla/

if the output as below, it means it is ok
