I use cryptographic module PKCS#11 to browse some sites. I load corresponding xxx.dll file : Options>advanced>Certificates>SecurityDevices>Load . The PKCS#11 device appears in the Device Manager list of devices. I can Log in this PKCS#11 reader and view data. "OK", View Certificates - I view this certificate. "OK" and quit Options menu. If I close the FF browser, these settings was lost and I have to install them manually again. How to save these settings ?

Thank you jscher2000 and cor-el for your suggestions!

I continue to analyze my case. The bank change the security rules and recommended to use their automatic update patch. Of course I did this. But their patch do not removed their old add-on on my current FF browser. This old add-on prevent saving the new PKCS#11 device data on FF closure. Solution was manually to remove this old add-on and reinstall the trust chains.

I consider the case closed!

Hi stefan9, when you import a personal certificate to Firefox, it should be saved in a file named cert9.db or cert8.db (older versions used cert8.db). Can you tell whether that file -- located in your currently active profile folder -- is updating when you import the certificate? If not, perhaps the file has become corrupted or locked.

Aren't security devices stored in secmode.db in Firefox 52 (55+: pkcs11.txt)?

So maybe check for issues with this file.
