Hello Ahmad, 

 

It could be an issue related to 'TLS 1.3 Hybridized Kyber Support'.

 

Changes from the update on Google Chrome version 124.0.6367.61 and in Edge version 124.0.2478.51 (Edge is a derivative of Chrome) where the variable 'TLS 1.3 Hybridized Kyber Support' was changed from disabled to enabled adds extra data in the client hello message.

This change increases the time webpages load when the firewall policy is in flow mode.  In some cases, the pages do not load completely and the page tab shows an icon spinning for a long period. 

 

Please check this document, https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-Web-pages-not-loading-or-taking-too-...

 

Regards!

If you have found a solution, please like and accept it to make it easily accessible to others.

Hi Ahmad

Does it have any relationship with DNS (53) and DNS over SSL/HTTPS? You may check if there is a difference between your Firefox and Edge on that side.

You may also check in Web Filter logs, under Log & Report menu, to see if there is relevant logs.
