Description:
After upgrading to Firefox 135, we are experiencing an issue where file uploads using the multipart/form-data format fail to complete successfully. The issue occurs when submitting a form using the jQuery Ajax method ($.ajax) with enctype="multipart/form-data".
Key Observations:
• The same implementation works fine in Firefox 133 and other browsers (Chrome, Edge, etc.).
• Our SSL certificate is rated B on SSL Labs, with TLS 1.3 enabled.
• The issue persists even after disabling browser extensions and clearing browser cookies/cache.
Environment Details:
• Browser: Firefox 135
• Form Submission Method: $.ajax({ type: "POST", enctype: "multipart/form-data", ... })
API Response - 520: Web server is returning an unknown error
We suspect this might be related to a security policy change in Firefox 135 affecting file uploads. If anyone has encountered a similar issue or has insights into recent changes in how Firefox handles multipart/form-data, please share any possible solutions.
Would appreciate any guidance or workarounds!
