Here’s how you can do it: Open Firefox Preferences: Click on the menu button (three horizontal lines) in the top-right corner of Firefox, then select "Preferences" (or "Options" on Windows). Go to Privacy & Security: In the left sidebar, click on "Privacy & Security". Scroll down to Permissions: Find the section labeled "Permissions". Manage Permissions: Look for the "Play DRM-controlled content" option and click on the "Settings…" button next to it. Block HDR on Specific Sites: In the dialog that appears, you can add specific websites where you want to block HDR content. Enter the URL of the website and choose "Block". Save Changes: Click "Save Changes" to apply your settings. </blockquote> Thanks for the reply, but your instructions does not appear to be correct.
