I am running a MacBook Pro with latest Firefox. I clicked on the ‘upload’ button. As it has done dozens of times before, a window pups up for me to choose the file. I do so.
Immediately another dialog box opens, advising me that I can drag a file anywhere to upload it, or I can browse my computer for the file. This dialog has never appeared to me before. I chose the ‘browse’ option. That gives me the Finder window again. I click on the desired file.
That gives me another dialog box stating " We’re sorry, an unexpected error has occurred."
So I tried restarting the whole thing, this time dragging and dropping. Ended up with the apology again.
Thanks for reaching out, and I’m sorry you hit a snag. Are you still unable to upload your file using Firefox? If so, could you please share the file you’re having trouble with? You can post it here, or email it to us at email@example.com, and we’ll be glad to take a look.
It’s curious. I just uploaded another random file with no difficulties. I uploaded THIS file easily using Safari on my MacBook Pro. I uploaded this file without issue using Firefox, but I still can’t get that first file to upload in Firefox.
I’m adding ‘swap browsers’ to my arsenal of troubleshooting tools.
