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?
Thanks, but I can't get that far. The extensions that I download (install on my computer) from the App Store do not install in Safari. Opening a downloaded extension presents a dialog box, I click the button "Quit and Open…" at the bottom, and nothing happens, the box does not disappear and when I check Safari preferences>Extensions, the downloaded extension does not appear in the sidebar on the left.
