Some solid colours on certain webpages do not appear whilst on Firefox. The background will show up instead of the colour the image should be. I have tried to delete the cookies and cache on Firefox as well as trying Firefox in troubleshoot mode to no avail. Whilst writing this question, I have also discovered that taking a screenshot of the issue shows how the image should look as opposed to what the screen shows. Attached are some images of the issues I am facing, two images are of what appears on the screen and one image is the screenshot from the webpage which is what should have been shown. Apologies for some of the photos, I had to take a photo of the screen with my phone to show the issue. I have also closed the browser multiple times and restarted my computer, any help would be appreciated. Thanks in advance.
