In safari, cannot attach files in gmail

I'm having the problem in Safari, but not in Firefox. In Firefox I am able to attach files.

Dragging and dropping the file seems to work to attach files in Safari. Try that and see if it works.

See the main thread on this debacle: https://discussions.apple.com/thread/252051818

Best report it via feedback - links in that thread for user feedback and developer feedback.

I also have this problem. The "attach file" button works with gmail on my Windows desk top, and used to work on this new MacBook Pro (macOSMojave version 10.14.6), but stopped working a few days ago.

I've cleared the cache and history, but there is no change. I'm not skilled in nor interested in a "reload" of Safari or upgrade. "Attach file" such a basic function of any email program that should be working and Apple Safari should have a basic "fix" or understandable work around. "Attach file" on gmail is working on my iPhone and on my Windows desk top, so this appears to be a MacBookPro isolated issue. Odd that there is no help available.

I have the same problem although it only started in mid January, before that I had no issue.

Problem - Using gmail in Safari, clicking the attach button does not produce the finder window. As far as I can tell, nothing happens when clicking the button. It is occurring on my iMac, I am also running Mojave (macOS10.14.6)

Dragging & dropping the files works but it's really clunky.

Surely the problem could be resolved?

I have the same problem, using Version 14.0.1, and have tried (without success) the same suggestions. The Attach button used to work normally, but now it doesn't. It works fine in Chrome. Surely someone can help with this?

I have this problem also. I am unable to attach photos on my gmail - nothing happens when I click attach. I also can't attach photos when selling on Ebay. This was working perfectly until October 2020 after an update. I use Safari and have also tried on Firefox with the same result.,. what has happened and how can I fix it. it is very frustrating as I use that feature a lot. I am having to do most things on my phone now instead of my macbook.

WORK AROUND - Drag and Drop the file you want to attach into Gmail Safari. The paper clip button does not work. APPLE PLEASE FIX! (but why would they care about a Google site? oh well...)

Thank you! It's a bit of a nuisance, but it works.
