Google know that the safety and reliability of your Gmail is super important to you, which is why they’re always working on security improvements like serving images through secure proxy servers, and requiring HTTPS. Now, Gmail on the desktop is becoming more secure with support for Content Security Policy (CSP).
There are many great extensions for Gmail. Unfortunately, there are also some extensions that behave badly, loading code which interferes with your Gmail session, or malware which compromises your email’s security. Gmail’s CSP protects you, by stopping these extensions from loading unsafe code.
Most popular (and well-behaved) extensions have already been updated to work with the CSP standard, but if you happen to have any trouble with an extension, try installing its latest version from your browser’s web store (for example, the Chrome Web Store for Chrome users).
CSP is just another example of how Gmail can help make your email experience safer. For advice and tools that help keep you safe across the web, you can always visit theGoogle Security Center.
