I wanted to completely disable TLS 1.3 when using Firefox, so I set security.tls.version.max to 3 (which corresponds to TLS 1.2). That worked up until I got version 140.0.4 installed - now it completely ignores this setting no matter what I set. I tried using cloudflare-ech.com website for test and it confirms that my browser uses TLS 1.3 with ECH. I also tried modifying security.tls.version.fallback-limit to 0 and security.tls.version.min to 0 to get a possible range of TLS 1.0-1.2, but it still uses TLS 1.3.

My mobile package site shows mixed-content warnings on Firefox — how can I fix this? Hello everyone, I run a website, which provides information about mobile phone prices and SIM packages in Bangladesh. Recently, I noticed that when users visit some pages in Firefox, the browser shows a “mixed-content” warning or blocks certain scripts. The same pages load fine in Chrome. All my URLs use HTTPS, and I’m using a LiteSpeed server with Cloudflare CDN. Could this issue be related to how Firefox handles external resources (like embedded operator banners or analytics scripts)? What’s the best way to debug and fix mixed-content problems in Firefox Developer Tools? Any detailed guidance or best practices would be greatly appreciated. Thanks in advance!
