Please sit back and relax™ while this script tests your browser. This may take a while (about 2 minutes actually). Firefox users might want to check "Do not ask me again" in their "Unresponsive script" dialog.
The script constructs very long strings and tries to save them to
When that fails, it reports last successful length and current failing length.
Last time I've checked, Chrome 6.0.472.36 beta let me save 2600-2700 thousands of characters, Firefox 3.6.8 - 5200-5300k, Explorer 8 - 4900-5000k, and Opera 10.70 build 9013 popped a dialog, letting me give the script unlimited storage. Spec arbitrarily recommends 5 megabytes of storage, but doesn't say a thing about actual characters, so in UTF-16 you get twice less.
At any moment you can

AFAIK, there's no way to adjust quotas for Chrome/Safari/IE.
