In Opera you can simply type in opera:webdatabases
in the address field and delete all the web SQL databases stored on your computer.
How do you do the sam
Here is a node script that deletes the indexedDB directory for every website.
C:\Users\\AppData\Roaming\Mozilla\Firefox\Profiles\<*>.default\indexedDB
based on Aadit's answer.
var userName = "myWindowsUserName";
var fs = require("fs");
var root = "C:\\Users\\" + userName + "\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\";
var dir = fs.readdirSync(root);
var deleteFolderRecursive = function (path) { // http://www.geedew.com/2012/10/24/remove-a-directory-that-is-not-empty-in-nodejs/
if (fs.existsSync(path)) {
fs.readdirSync(path).forEach(function (file, index) {
var curPath = path + "/" + file;
if (fs.statSync(curPath).isDirectory()) { // recurse
deleteFolderRecursive(curPath);
} else { // delete file
fs.unlinkSync(curPath);
}
});
fs.rmdirSync(path);
}
};
var anyRemoved = false;
for(var i = 0; i < dir.length; i++) {
if(/\.default$/.test(dir[i])) {
var idbPath = root + dir[i] + "\\indexedDB";
var idbDir = fs.readdirSync(idbPath);
for (var i2 = 0; i2 < idbDir.length; i2++) {
anyRemoved = true;
var rmDir = idbPath + "\\" + idbDir[i2];
console.log("removing: " + rmDir);
deleteFolderRecursive(rmDir);
}
}
}
if(anyRemoved === false)
console.log("No indexedDB files were found.");
setTimeout(function () { }, 1000 * 5);
