People conflating the rollout of WebExtensions Manifest V3 with "Killing adblockers" is doing such a disservice because it gives asstroturfers the easy out of just saying "But Firefox is moving to Mv3 too!"
It's not the Mv3 that's doing it. It's the deliberate limitations on the API endpoints used for the filtering that are baked into Chrome's handling of it. Limitations Firefox has already removed.
@trysdyn I do sincerely hope people make an effort to remove the limitations on other chromium browsers like Vivaldi. Or more browsers move to gecko. I'm less than enthused with the response so far though...
