How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

Isisombululo esikhethiwe

Enabling sending DNT means that Firefox adds a DNT=1 header to the HTTP request headers, so you end up in a group that has this feature enabled, not a lot of browsers support this and it is not likely that a website support and honor this request. You can see this in the Network Monitor.

Yeah, i know it's that extension, was woondering if it is true that using duckduckgo search without the extension is a security / privacy risk, like i said an article i read claimed duckduckgo search must be used in combination with the duckduckgo extension otherwise do not track wont work, but is that true or wrong? And anyways i have set to not track in firefox to always, why wont it work then?
