I’m observing an intermittent issue with a Safari Web Extension on macOS 15.7 (Safari 26.0.1). After installing the Safari extension from the App Store, it appears under Settings → Extensions, but the enable checkbox is often missing.
Sometimes, after restarting Safari multiple times, the checkbox becomes visible. However, even when I manage to enable the extension, reopening Safari often hides the checkbox again.
However, I don't see this issue in safari 26 with macOS 26
- I’d like to know if this behavior is a known issue with Safari 26 or macOS 15.7?
- Any workaround available?
