This is not feasible in Blokada, as the app does not interfere in the source code of pages.
I would like to modify the source code of the default 404 page. The 404 pages currently display some text in Android with the image of a green android robot. I’d like to modify this and display a plain white background page. How could I do it in Android? I use Chrome.
Thank you.
Well as an educated guess I would say it was technically quite difficult to achieve within a browser that doesn’t allow much configuring. 404 is a little different to no dns record as it comes from the website server and you would have to intercept the info.
