That's interesting. I'm using the Adguard from the Edge store, so I still have custom filters enabled. Seems only people using the Chrome store version have been updated with that change. Also sounds like Adguard is purposefully not pushing the latest version to the Edge store to avoid issues like this.

They did say they'll get the issue resolved in time. I use another extension that requires a filter list or things start to go haywire. I'd probably give up that problematic extension before going back to Firefox.

Reading that, I am still sticking with Adguard over uBO because it does sound like they are at least trying to implement these things. uBO is just pointing people towards FF.
