Seems to work well in general, but there are a couple of annoyances! First, when OptMeowt is enabled on Chrome's Extensions page (even if I use its "Disable" option -- the pause button icon in its menu), I can't enter my bank's web site (hosted by fiservapps.com). After login, I immediately get a dialog box with a message from the site: "For security reasons, your session has ended. Log in again." (I sent an email to an OptMeowt developer a couple of months ago about this, but received no response; I now see I can report an issue on GitHub, so I am trying that -- https://github.com/privacy-tech-lab/gpc-optmeowt/issues/441.) Second, when I am in a Google Meet meeting, Meet displays a warning banner saying that I have a Chrome extension that might cause meeting quality problems (linking to https://support.google.com/meet/answer/10550593?hl=en#meet_extension). I narrowed it down to OptMeowt -- when I disable it and refresh the Meet tab, the warning goes away. I haven't actually noticed any quality difference either way, but the banner sure is intrusive, and OptMeowt isn't even intended to be a Meet extension, as far as I know. I assume it must be doing something to trigger Meet's warning. (https://github.com/privacy-tech-lab/gpc-optmeowt/issues/442) As a result, I've had to stop using OptMeowt on some of my computers, and have substituted Privacy Badger, which seems to be decent, with no annoyances so far.
