Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.

More details: My OS Is Debian 11 Debian built-in Document Viewer also display pdf file correctly.
Is there a reason for the old version of Firefox, have you tried a new version? Can you provide steps to replicate the issue?

I think it is something wrong in profile, because I download the firefox from "https://www.mozilla.org/en-US/firefox/all/#product-desktop-release" and it work fine with default profile. But when it use old profile I assign to firefox, it will be wrong.
Thank you.
