In a previous post I have been talking about creating and deleting a database. The creation/opening of a database is supported in all the major browsers, but deleting isn’t. Only Internet Explorer currently supports deleting your database trough the IDBFactory interface.

Because we have been playing for a while now, it’s interesting we can delete our database so we can rebuild it from scratch without having to use a new name for our database. I’m only used to work on windows machines, so the solution I will propose will probably only work under windows. If you are using an other operating system, it will work on the same way, but you’ll have to look where you can find the databases.

Firefox

The Indexed DB databases of Firefox can be found on the following location:

<location of the windows user profiles><account name>AppDataRoaming
MozillaFirefoxProfiles<some random characters>.defaultIndexedDB

In my case this is:

C:UserskristofAppDataRoamingMozillaFirefoxProfiles tvv6t475.defaultindexedDB

You will find a folder with your current domain. Delete these folder, and you can start all over again. In my case, I get the following:

http+++localhost+50350

I have to notice that the AppData folder is a hidden folder, so it is possible you won’t see it when going to your user profile directory.

Chrome

The Indexed DB databases of Chrome can be found on the following location:

<location of the windows user profiles><account name>AppDataLocalGoogle
ChromeUser DataDefaultIndexedDB

In my case this is:

C:UserskristofAppDataLocalGoogleChromeUser DataDefaultIndexedDB

You will find a folder and a file with your current domain. Delete these files, and you can start all over again.

In my case I get the following:

folder: http_localhost_50350.indexeddb.leveldb
file:     http_localhost_50350.indexeddb
