Hacker News announce Mozilla begins rolling out new Site Isolation Security Feature for Firefox Browser
Mozilla has begun rolling out a new security feature called 'Site Isolation' for its Firefox browser to protect users against a new class of side-channel attacks from malicious sites.
Once activated the browser will load each website you browse using any one browser tab using a separate 'operating system process' to block untrusted code embedded by hackers in a website that you are unwittingly browsing in an adjacent tab.
Mozilla state: "Isolating each site into a separate operating system process makes it even harder for malicious sites to read another site's secret or private data."
Sounds great but is it good practice to browse lots of websites in adjacent browser tabs at any one time?
Do you browse lots of websites in adjacent browser tabs at any one time?
If YES then the above news will help protect you from 'side-channel attacks'.
Maybe you can better protect your website from such attacks by not browsing the web in this way, and especially not opening multiple tabs whilst being logged into a website (especially an important or sensitive website).
We recommend changing your browser security settings to clear the cache every time you close your browser.
And, frequently closing your browser (to clear the cache) after visiting and accessing important or sensitive websites.

Protect your device, browser & web connection
When thinking about website security, it is easy to overlook the:
- device (operating system) used to connect to your website,
- the way you connect (your web browser) to the internet, and
- how you connect (in the clear or via encryption).
