10 months ago Hey @salvobee! We're sorry to hear that you've hit this issue. 💛
However, it looks like you forgot to fill in the reproduction repository URL. Can you edit your original post and then we'll look at your issue?
We need a public GitHub repository which contains a Laravel app with the minimal amount of Filament code to reproduce the problem. Please do not link to your actual project, what we need instead is a minimal reproduction in a fresh project without any unnecessary code. This means it doesn't matter if your real project is private / confidential, since we want a link to a separate, isolated reproduction. That would allow us to download it and review your bug much easier, so it can be fixed quicker. Please make sure to include a database seeder with everything we need to set the app up quickly.

Problem description
I have encountered an issue related to the default action for importing records via CSV file upload.
When attempting to upload a CSV file using Firefox on Windows, I encountered a problem with the accepted MIME types by the form. The form indicated that it expected either "text/plain" or "text/csv." I attempted to create the CSV file by manually assembling some lines with Notepad++ and saving the file as plain text with a .csv extension. Additionally, I exported a file from Excel using the CSV format. However, regardless of these efforts, I was unable to upload any CSV file.
Upon further investigation, I used JavaScript to check the detected file type by my browser (Firefox) for these created files. Surprisingly, it was identified as "application/vnd.ms-excel." In contrast, Chrome detected them as "text/csv."
I delved into this issue and discovered that Firefox relies on the system registry to determine MIME types. I found a relevant discussion on the Mozilla support forum: Mozilla Support Forum.
I understand that this behavior might be influenced by how my system is configured to handle these types of files. However, I believe it is important to highlight that users of an application utilizing this functionality may encounter difficulties uploading files. Therefore, it would be beneficial to explore a solution to handle this use case effectively.
Expected behavior
The file upload should accept CSV files regardless of the system's MIME type detection, ensuring a smoother user experience across different browsers and configurations.
