Writing Extensions More Securely
Friday, July 22, 2011
Extensions are powerful pieces of software in modern browsers, and as such, you should help ensure that your extensions are not susceptible to security exploits. If an attacker manages to exploit a vulnerability in an extension, it’s serious business because they may gain access to the same privileges that the extension has.
The Chrome extensions system has a number of
chrome.tabs.create
, you don’t actually need the tabs permission.
Use content_security_policy in your manifest
Starting in Chrome 14, we will begin supporting
few more
examples of the issues discussed here in our extension docs. We hope these recommendations help you create better and safer extensions for everyone.

Chrome Extensions: Now with more powerful scripts and improved proxy management.
Wednesday, July 13, 2011
In Chrome 13, we added some new capabilities to content scripts and proxy management.
First, you can now make cross-origin XMLHttpRequest calls with the privileges of the extension directly from your content script. You will no longer need to relay these requests through a background page; this should simplify your code. In some cases, it may even eliminate your need to use a background page. Here’s a
Book Burro
- will now work in Chrome.
Second, we improved how
Proxy Extension API
, you can now configure proxy settings by choosing from several options including auto detection, the host OS’s system default, PAC scripts or fixed
Proxy SwitchyPlus
.
Let us know what you think of these new features and what else you might like to see us do by joining the discussion at chromium-extensions@chromium.org.

Using Cross-domain images in WebGL and Chrome 13
Wednesday, July 6, 2011
A few weeks ago, we became aware of a
CORS
.
use of CORS
on their images.
You can test this new behavior today using images from Picasa, which already sends a CORS header allowing cross-origin requests, and the
Chrome dev channel
.
