mTLS not working on newer version (>128, Debian)

Hi,

I am using mTLS to authenticate my computers reaching websites I manage. I imported client certificate on firefox and cloudflare is checking if the client is sending the right certificate. I am using Debian and Windows. On Debian (13), everything was working great until the version 140 ESR. I don't know why but the client certificate is not sent to cloudflare, sometime it is (when CTRL+F5) but no CSS is rendered. So I can't reach my websites. Firefox is still asking for the right certificate to send but that's all. This is weird because on the same version on Windows, with the same certificate, it is working. I tried newer version (144.0.2) on Debian but it is not working. The version I use at the moment is 128.14.0esr. Cloudflare is blocking the traffic because no certificate is sent. If I disable the rule, it is working.

Could someone help me? Feel free to ask for more details.

Around 12/28/2024 my LastPass Password Manager extension dropped off my Firefox. When I tried to reinstall nothing happens except the flashing dots, which just go on. The LassPass extension does work on my Chrome browser (only used as a backup, Firefox using Duckduckgo rules)

Steps I have taken. Relaunched firefox. Rebooted laptop Deleted all Lastpass cookies. Did a firefox refresh. Tried to install older version of lastpass, they download but won't let me add.

Please Help? Thanks

Hi guys, Had Firefox as network default browser for decades. Now I have a problem with my DNS pihole filter, firefox just goes around it. I've read countless articles on how to stop this, I've tried DoH 0 and DoH 5, I've placed a file policies.json in a distribution folder. I've tied everything I can find on the net. Nothing and I do mean nothing, had the slightest effect. Firefox goes around whatever I try.

I've spent many, many hours on this please tell me how to kill this, I'm forced to use another browser at the moment, which is painful.

version 142.0.1 64bit W11.

Thank you Bob.

TLS settings from about:config don't work in Firefox 140.0.4

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.

I am trying to login to email service tuta.com. Due to malicious actors, the site is being blocked by Firefox when it should NOT be. Malicious actors have made false reports to create a DDOS on Tuta. When I try to connect to the site I get this message: "Did Not Connect: Potential Security Issue"

How do I tell Firefox to stop blocking this site as there is NOT a security issue.

passport.moi.gov.af has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
