Where are pre-installed Firefox personas located?

If anyone can help me with the information where/which folder does the Firefox personas reside, so that i can push these to all the libreoffice organization wide users.

Note: most of the users either do not have internet or they are under restricted network, so no one can connect to firefox themes URL.

OP: @slax .

There are no Firefox personas included in the default LO install. The answer here indicates the location for the persona files under the user profile and how to manually install them.
