This is most likely a limitation of the Firefox plugin or is related to setting up a naming convention. From the SQLite documentation:
The default value for SQLITE_MAX_COLUMN is 2000. You can change it at compile time to 32767. On the other hand, many experienced database developers will argue that a well-normalized database will never need more than 100 columns in a table.
Solution: use sqlite3 command line interface.
