Until this addon has Windows support - whatever that may require to enable - it will mean that Firefox is not a browser I can use fully. Fully 90% of my passwords are handled in the Apple Keychain manager system and I have little incentive to change this. While Chrome's lack of support of adblocking extensions are a dealbreaker for it, it did at least allow me to seamlessly manage passwords across my iOS device and Windows PC with no cost and without having to adopt a browser on iOS other than Safari, which works perfectly well for my purposes. I doubt this review will ever be seen or considered by the Apple dev team, but this omission of Windows support is a glaring one.

It keeps telling me I need a more recent version of MacOS even though I'm on 15.3.1

Sometimes it works well, sometimes it's a nightmare. There should be a way to exclude some sites as it simply doesn't function. For a few you take the risk of being locked out due to too many bad logon attempts because it won't get out of your way so you can logon properly.
