Attachment: Screenshot 2025-04-24 173933.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:137.0) Gecko/20100101 Firefox/137.0

Steps to reproduce:

Whenever I download a file from my inbox (Outlook Web) any attachment, the file name is appended by 'UTF-8' Word from start. For example, if file name is File.docx then the downloaded file will have name UTF-8File.docx. Moreover, outlook or Microsoft products are behaving strangely only on Firefox. For example, sometimes Copilot loads and sometimes it doesn't.

Actual results:
