Normally I'd agree with you but Sqlite is a pretty standard and is supported just about
everywhere, and the flexibility improvements it adds to Firefox are significant and definitely
worth it. If you want to manipulate the data outside of FF, run "sqlite3 path/to/db.sqlite"
and manipulate whatever you want with standard SQL. You can also use just any programming
language there is to automate your FF-data manipulation tasks, something that was way harder
