Ajax File Upload is not working in the latest Chrome Version 83.0.4103.61 (Official Build) (64-bit)
Ajax File Upload is not working in the latest Chrome Version 83.0.4103.61 (Official Build) (64-bit) as the update has affected images/media widgets. The POST request to upload files shows as canceled and the upload fails.
When “iframeSrc” is set to “javascript:false” on https pages, Chrome now seems to cancel the request. Changing this to “about:blank” seems to resolve the issue, but what other consequences might this have? Talk to our expert consultants to get this right.

Here’s what we do:
- Patch existing jquery.form plugin or update to a newer version.
- Test affected modules on Chrome version 83.0.4103.61
- Test jquery.form functionality on all browsers.
This problem seems to go away if we ensure the iframe jquery.form uses for the upload has an src of about:blank rather than javascript:false, which has been used for https requests for years.
