Hello, I’ve noticed that Firefox does not show the translation icon in the toolbar for a webpage, even though the page is in English. When I manually go to "Application Menu" → "Translate Page…", I receive the message: "Translation is not available for this page - Sorry, this language is not yet supported." However, if I click on "Change source language" and manually set it to English, the translation works correctly. It seems like Firefox is not detecting the language of the page automatically, and as a result, the translation feature does not appear unless I manually intervene. The issue occurred on this page: "https://mantisbt.org/docs/master/en-US/Developers_Guide/html-desktop/#dev.contrib.submit.before". I also looked for a way to report this issue, but I only found a form for reporting incorrectly translated words here: "https://docs.google.com/forms/d/e/1FAIpQLSdoRWnsHX6vVnGIRyLi4Kl-p0GrmeVIioqWsTz3aVTRfLScng/viewform". There doesn't seem to be an option to report entire sites where the translation does not work at all. I'm using: Firefox Desktop 138.0.4 (64 bit) on Windows 10 22H2. Thanks for your help.
