Against traditional browser extensions; there's still a lot of room to run to use LLMs and generative AI in this space for adversarial interoperability (imho).

Have your agent consume the Meta feeds of your choosing and process for your consumption accordingly, minus the ads. Won't be perfect, but will continue to get better if effort is put into it. Let the tokens do the drudgery of filtering ad content.

If someone wants to work on this (browser extension that uses LLM inference to process content for de-advertising), please create a bounty, and I will fund some of it (assuming sufficient copyleft license of code output to defend against future enshittification).
