Make sure you haven't enabled High Contrast mode in the OS settings.

Make sure you allow pages to choose their own colors.

• Settings -> General: Fonts & Colors -> Colors: "Override the colors specified by the page with your selections above"

Try "Never" if the default "Only with High Contrast themes" isn't working.

I tried it on Troubleshoot Mode and I was able to search and see the items. This means it could be some of the extensions that's causing the problem but when I switched it back to normal, it remains the same. The search is there but no items are shown like previously shared. I don't know what's up. Maybe deactivate each extension one by one and keep trying. I appreciate the help. Thank you!

and it was the Dark Reader extension that was giving me the problem after disabling and enabling each one by one. I removed it and chose a different Dark Mode extension and now I search again on eBay. I appreciate the help from those has reached out! Thank you!

Mark it as resolved and enjoy. ;-)
