Describe the feature you would like.

Unlike MySQL and other databases that use infromation_schema to store database information, Firebird uses system tables.

For example, the analog of information_schema.tables in Firebird database is the RDB$RELATIONS table, which is stored in each database instance and contains information about created tables (excluding system and monitoring tables).

More information about system tables in Firebird can be found in the documentation at https://firebirdsql.org/file/documentation/chunk/en/refdocs/fblangref50/fblangref50-appx04-systables.html.
