Add the ability to block a POST request depending on its body

[ArkadiuszMichalski]

It seems we can't block a POST request depending on its data. I wanted to block a POST request if it contains specific data, but I don't see an option for that. Any chance that this will be available in the future?

It's not feasible due to the limitations of the web extension APIs.

However, a hacky alternative solution is possible. I may consider adding this option in the future.

The current API is not sufficient for this purpose?

No. In mv3, only declarative rules are allowed to intercept requests.

Indeed, I have to wait for your hacky alternative solution (if it will be possible).
