Accessing firefox cookies.sqlite Error

Question

When I try to access cookies.sqlite found in my firefox profile folder, I get this error:

sqlite> .table 
Error: database is locked

What do you think the error is?

[Edited] After I close firefox and read, I get and error like this

Unable to open database "cookies.sqlite": file is encrypted or is not a database

[Solution]

I was using sqlite instead of sqlite3

Answer 1

Looks like you are opening it with an old version of sqlite. Use sqlite3 instead.

Answer 2

recent firefox upgrade (3.5 -> 3.6) brought another sqlite storing change, sqlite > 3.7.0 is now needed
