Can’t upload photos to Facebook from my MacBook

I spent 30 minutes trying to upload about 10 photos, but I only succeeded in uploading two. I’ve tried Safari and Chrome… I’ve tried uploading photos individually and in groups.

The rest uploaded part of the way, and then froze, seemingly forever, with this bar.

Oh, well… I guess that’s why I don’t upload many photos to Facebook.
