Hi Gary, it sounds like Firefox might be running in High Contrast Mode or Windows color filters are active. Please try the following steps to restore normal colors: 1. In Firefox, type `about:preferences` in the address bar. 2. Scroll down to “Language and Appearance” → “Colors…” 3. Make sure “Use system colors” is unchecked and “Override the colors specified by the page” is set to “Never”. 4. Click “OK” to save. If that doesn’t help, check Windows settings: - Open *Settings → Accessibility → Color filters* and make sure filters are **off**. - Also check *Settings → Accessibility → Contrast themes* and set it to **None**. After that, restart Firefox — your normal color screen should be back. Hope this helps! Sebastian
