Fn-Delete not working in file name field when downloading files from internet.

Interesting… I think I can see the difference between 151 and 153 … and given there has been a change about the "globe" shortcut (your Fn is mapped to Globe key, right?), it could have been affected. Or, well, the actual API for file pickers have changed, so the former one had no access to Edit menu, while the new one seems to consume the Fn+backspace key combo inside the Edit menu somewhere instead of doing the forward delete as is probably the thing you'd like to achieve.

Ooh I see it now, it triggers the "Edit" › "Delete" menu item, which, alas, only works on selections, but doesn't do forward–delete just right of the caret. (That's underwhelming.)

I'll check if this is tracked somewhere. Thanks for flagging this!

It's already filed:

I'll add some more details to the timeline.

Thank you so much for your prompt response. I really appreciate it, and I'm very impressed.

I look forward to you guys working your magic. Now I'd better make a contribution!

Thanks again.

It might be worth testing the same download dialog in another browser or a different macOS app to see whether it's Firefox-specific. If it only happens in Firefox, it could be a recent regression and may be worth reporting with the exact macOS and Firefox versions.

The bug timeline already has the regression range.

Thanks for the report!

FYI there's already a patch and a testing try/CI build (with instructions) in bugzilla.mozilla.org/2054565 if you wanted to confirm this also works for you as expected using that separate binary.
