DuckDuckGo® Browser review
If I need to check a booking on a studio computer, I want to leave the next person a clean browser window. In DuckDuckGo Browser I’d open a Fire Window for that one task. It keeps the session separate from my regular windows and clears its browsing data when I close it.
Clear the session you meant to clear
The Fire Button also works in a regular desktop window. You can clear data for the current tab or across the browser, and choose whether to keep history or cookies. I’d look at those choices before pressing it. If I’ve set a site to Fireproof, its cookies and site storage can stay, including the data that keeps me signed in.
Check what’s still on the computer
A call sheet I downloaded can still be in Downloads, and a bookmark I created can still be on the browser’s list. EFF’s Surveillance Self-Defense goes further into keeping identities separate and checking for copies of files outside the browser. I’d use the Fire Window for the booking page and deal with the file separately.
Anabel’s take
I’d use a Fire Window for a quick check and close it when I was done. If I was taking over the same studio computer every week, I’d also want to know which sites had been set to Fireproof and where the computer saves downloads.
