SignatureDoesNotMatch – Amazon S3 file opening issue in FireFox


Yesterday I see a case that my file on Amazon S3 wasn’t opening in FireFox but it was opening in Chrome and Internet Explorer 9.

The issue was character encoding. My filename was containing square bracket ‘[‘ and ‘]’.

‘[‘ converted to %5B and ‘]’ converted to %5D

So I learned a lesson to replace special characters.

Enable html5 in Firefox


If you are using Firefox 3.6 or above version, then you can enable html5 rendering by changing the configuration of Firefox.

Type about:config in address bar.

Type html5.enable in filter, and double click to set the value true.

Enjoy the HTML5!

To test the page, please create a  page named html5.html, and paste the following code:

<!DOCTYPE html>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
<title>SVG in text/html</title>
<p>A green circle:<svg> <circle r="50" cx="50" cy="50" fill="green"></circle></svg></p>

Save the page and open it in Firefox, you should be able to see green circle!
