I've been using uBlock origin for a couple of years now and loved it. Amazing just how many ad connections just one site can make. I had the same issue in version 1.28.2 as odelphi and lyggo did (both on July 11, 2020) where I can no longer allow a specific site in custom dynamic filtering. I WOULD have downgraded my rating like they both did but the developer in their release notes explained why they did it (recommending you use gray noop in almost all cases) AND also explained how to re-enable the green "allow" option for specific sites. (In Settings, enable "Advanced Settings" and click on the gears icon on the right. Go down the list to "filterauthormode" which should be set to "false" by default. Change that to "true", click the Save Changes button, and problem solved.) So if this is important to you, too, I'd suggest you TRY to use the gray noop instead of green "enable" as the developer suggests. That's what I'm going to do. If that doesn't work for you, you're still empowered to use the green "allow" option as before, so you have nothing to lose by trying out his recommendations. (Your existing "allow" choices appear to be grandfathered in, at least for ver. 1.28.2, even if you don't make this change in Advanced Settings.) So as long as I'm still empowered to override the developer's removal of that feature, I'll continue rating this extension with 5 stars. (Submitted July 15, 2020 for ver 1.28.2.)

1.28になって、ポップアップでの一時許可（緑）ができなくなって不便になった。
