This is just an idea and I haven't thought to closely about it yet, but what if we made a browser similar to Opera Mini? I.e. a proxy server on the backend would download the pages, render them and ship a snapshot of the DOM to the actual browser, only with all the links rewritten to point to itself?

Alternatively this could even work without a separate browser instance but the ux would be harder.

Obviously this could create a lot of privacy issues but it is not completely clear cut that it couldn't be better for some people:

• running ad and tracking scripts on my actual devices also comes with privacy problems.
• the server could be open source and the business model could be to sell access to pre-configured, hosted proxies.
