Safari extensions not loading
macOS 11.2.1; Safari 14.0.3: After I install and open a Safari extension, I am presented with a dialog box with a button on the bottom “Quit and Open Safari Extensions Preferences…” I click on the button and nothing happens; the box stays on my screen; the extension is not loaded. It happens with every extension I install, so it does not appear to be a developer issue. Anyone know of a fix?
