Migrate the site and master passwords and logins for Firefox to light

To expedite my USB mobile browser, I want Firefox v.30 a light v.30.
Only now I noticed I still signons3.txt instead of key4.db and cert8.db instead of cert9.db in the Firefox profile.
https://support.Mozilla.org/en-us/KB/recovering%20important%20data%20from%20an%20old%20Profile#w_your-important-data-and-their-files Specifies not how to upgrade these versions, or some other answers, for example https://support.mozilla.org/en-US/questions/767061.

Copy of signons3.txt, signons.sqlite between profiles has not helped get my password or my master password in light.
Any thoughts why? Because I signons3.txt instead of key4.db, or because I use the master password?

Note that you can use a CMD or BAT file to set an environment variable temporarily for this start.

Set NSS_DEFAULT_DB_TYPE = sql
Start "" "path to Firefox\firefox.exe" PEI

I noticed that SQLite files are much larger, because likely Firefox uses a minimum size to avoid problems with fragmentation as is done with all files in SQLite.

Note that Firefox is actually declining many SQLite files and replace them with the files of JSON type (extensions.json, addons.json, search.json, logins.json) to avoid the problems that SQLite gives in some cases and make it easier to keep the database in memory to boost performance.
