This is related to following unofficial patch for Bug 1716707 I do use:
https://bugzilla.mozilla.org/attachment.cgi?id=9268903&action=diff

Without this patch these text boxes are correct. But everything else is blue... So it should be applied only sometime?! When?

Maybe Lee will have an idea?

That patch is correct, but there are probably parts of the code that render into an endian-correct byte order, that if you are going to swap at the end, would no longer work. Somebody would need to investigate and correct.

Hello! Thank you for submitting this issue I have tried to reproduce the issue on my end but unfortunately I wasn't able to with firefox 129.0a1(2024-06-12) on Ubuntu 22.04 and Windows 11.
Could you please answer the following questions in order to further investigate this issue?

1. Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

4. Could you please provide an HTML file example?

Sorry for the delayed response. I think the main issue here is that SPARC is a big-endian platform, so I don't expect it to be seen on Ubuntu or Windows.
