I’ve noticed a recent change in DuckDuckGo’s file upload behaviour and I’m trying to confirm whether others see the same.

When using an <input type="file" accept="..."> with multiple extensions (e.g. .pdf,.docx,.txt,.jpg):

• In Chrome and Firefox, the file picker groups all accepted types into a single filter (e.g. “All supported types”).
• In DuckDuckGo, each extension is listed as a separate filter.
• The picker always defaults to the first extension in the list, instead of a combined filter or the last-used selection.

This makes file selection much more cumbersome.

Important:

• This behaviour did not occur before (started ~1 month ago)
• Same system, same websites, same test cases
• Only DuckDuckGo is affected

Repro test:

Has anyone else noticed this?
Is this intentional or a regression?

It looks like DuckDuckGo is not aggregating the accept attribute into a single filter and is instead passing extensions individually to the OS picker.
