My attempts for searching similar questions
- Profile Picture Problem: I'm using Firefox 66.0.2 (64-bit) on Xubuntu 18.04 LTS. I've tried clearing browser cache, but the profile picture is still broken.
- Where's My Profile Picture?: The accepted answer suggests the possibility of image URL corruption. However, the above downloaded JPEG file shows that the URL can deliver the image content.
- Facebook imported picture is breaking the network profile design: The linked question is also about profile picture display error for images from Facebook. However, this problem is different since this is a missing content error, whereas the linked post is about a content layout problem.
