Edge is dropping support. Helium is not a major browser.

Brave is the only one that might be considered a valid point. However, because of Chromium dropping support they've had to implement a custom bypass to support Manifest v2 and they are also hosting a version of uBlock Origin for Chromium on their own servers.

It's really questionable how long this state of affairs can go on for. Brave has said they will support it "as long as they are able" but Google could easily just remove the `webRequest` API from Chromium or the engineering burden to keep it alive might just get to be too much

Unfortunately, I think it has an expiration date on any Chromium-based browser.
