Send "Save-Data: on" Header
Added by VR 25 over 3 years ago.
Updated about 3 years ago.
Description
In combination with images and third party domains blocking, this would help save even more data.
I personally have a genuine need for agressive data saving features.
Speaking of that, there's a privacy app that can selectively block third party domains without the need for a custom webview: https://github.com/tobykurien/WebApps .
Such a feature would be another great addition to Privacy Browser.

Interesting. I have never heard of the Save-Data header. Doing a little bit of research, it looks like almost no sites actually use it.

Which websites that you use regularly actually save data with this header turned on?
In addition, there are negative privacy implications with enabling this header as it will increase the accuracy of browser fingerprinting.
I Had no idea the number of sites that support this header was even smaller than that of those which honor DNT.
We're really in the "saving data doesn't matter" era.
That being said, even worse than DNT, there's no benefit in sending this header after all.
That article was a good read, thank you!
I am going to leave this feature request open for a while and see if anyone else has a compelling use case for this header.
Regarding the blocking of third-party requests, I like to keep feature requests to a single topic. From what I can tell, the app you link to doesn't do anything more sophisticated that what Privacy Browser already does with the block third-party requests option. However, if you are aware of details I didn't see you can open a new feature request or post on the forum to discuss it.
- Status changed from New to Closed
I am going to close this as it doesn't look like there is any benefit. Feel free to add a comment and I can reopen it if there are scenarios where it would be helpful.
