Thank you for reporting. Unfortunately, It's not reproducible here on Firefox 127.0 (64-bit) on Windows 11. Is it correct that the following is the reproduction steps? 1. run Firefox 127.0 (64-bit) with clean profile, on Windows 11 2. In normal window, type https://ideosorter.pages.dev/ to location bar and enter 3. Select "New private window" from the menu 4. In private window, type https://ideosorter.pages.dev/ to location bar and enter For me, there's no difference between step 2 and step 4. Neither of them don't show "undefined", but they look "expected" rendering (attached the screenshot), that looks identical to what I observe on https://ideosorter.github.io/ Can you please check the following? * (A) Does the issue reproduce on clean profile? (Just to make sure it's not caused by some settings) * (B) When you open the [Network Monitor](https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/) and reload the page, do you any difference between "good" case and "bad" case? is there any resource gets blocked etc? * (C) When you open the [Web Console](https://firefox-source-docs.mozilla.org/devtools-user/web_console/) and reload the page, do you see any error message or warning message, or any difference between "good" case and "bad" case? Also, if you've already located where the difference happens in the source, can you post the details, such as file's URL and line number, and what the types and values there are? If you have minimal testcase, that's also helpful.
