I have an older RAID system that I need to login to from a browser. Is there a way to remove the TLS 1.2 protocol for local NAS drives that are only 2 feet away but I can not connect anymore.

Hello if i enter proxy and ip address in firefox in Manual proxy configuration section then when i open a website its asks for username and password my question is can proxy owner see my data and i am using https websites like post data ?

Hi there. I tried to connect to a library WiFi which required to enter a username and password in a login form to have Internet access. First of all, the firefox could not open the login page normally (automatically). I had to check the Gateway IP address of the WiFi connection and find the login page manually (same problem with chrome). But when I tried to submit the login form, I got "Secure connection failed" error in my firefox (PR_END_OF_FILE_ERROR). Then I tried chrome and the form submision worked fine. I experienced this same problem both on Windows 10 and Debian 12 (could not submit the form on firefox, but it worked on chrome), so the network setting misconfiguration scenario is unlikely. I also read the mozilla page related to the error but it was not helpful. What is the problem and how could it be solved?

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 notice with latest firefox updates the https:// is missing from the URL line. When I login to secure sites (ie banking), no https://. I've toggle and play with the http and dns settings. Is this a new feature or should i start changing my passwords? Thanks.

I am trying to work with an older piece of equipment that has an internet interface, a local IP 192.168.1.x

When I try to connect with FireFox I get the error "Warning Potential Security Risk". When I continue the error message is "MOZILLA_PKIX Error Self Signed CERT"

Accepting the "risk" things seem to work for a while. However, after several timeouts and reconnects FF will not connect. If on the other hand I just let things run without making changes the connections stays up without an issue (until I start making adjustments).

Looking at the certificate (from ~2012) yes it is from the manufacture. There is also a "Finger print"

Is there anyway to bypass this warning/blocking to eliminate the FF/equipment interface from my troubleshooting problem?

Thanks, Lou

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.

Warning: Potential Security Risk Ahead

Firefox detected an issue and did not continue to dinajpureducationboard.gov.bd. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

Until I installed the latest update (136.0.1) I could open Firefox and navigate, never having to log into PW manager until I came to a site where I had to log in and use a saved PW. I have many sites where my login is remembered, and I don't have to log in, so this isn't needed most of the time.

Now EVERY time I open Firefox that request for my primary PW pops up and I have to hit CANCEL twice to clear it before I can to anything. It's an annoying pain in the tush.

How do I turn this off, or set it so that that pops up ONLY when I have to log into a site?

Thanks.

I used Chrome until two days ago. I just got tired with how shitty the browser was, how bloated it made my computer, and how much Google treats everyone like a data product. However, I use hella google systems from Voice to Chrome to Drive to more and it all worked great together. Choosing to change to Firefox wasn't an easy decision but I knew it was a good one

Which makes it super irritating that some of the functionality is already facing problems. I have shortcuts I built to make it easier to study or do random things so I don't get distracted or tired. One shortcut is clicking a key that should launch UWorld in my default browser & use Lastpass to autologin (I couldn't get it to launch the service but that was a separate issue).

I check if autologin was on for the password on LastPass I've allowed all permissions to the LastPass extension I clear my cookies on UWorld & turned off enhanced tracking protection for the UWorld login portal site

What should I do to fix my one button shortcut again?

I really don't want to go randomly turning off every protection that Firefox gives me to figure it out so I'd appreciate someone who understands the browser better helping me out. Also, bonus points if you can help me build a single shortcut button on my Mac that can launch UWorld & navigate me straight to the question bank. (I do think the issue with autologin on LastPass is going to become more of an issue as I start opening up more websites I used to use on Chrome so I'd rather nip it in the bud before I see the problem occur more often)

Open my desktop and NordVPN starts up. The Firefox extension frequently shows I an not connected via the VPN whilst Nord says I am. I have in the past clicked on the extension to connect the VPN and this has worked but recently I just get an error. Same thing occurs with NordPass.

I was reading about CSS custom variables at https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_cascading_variables/Using_CSS_custom_properties, and noticed that the example at "Using @property to control inheritance" does not work as described in the latest Firefox (115.21.0esr, 64-bit. on Windows laptop).

More specifically, both the parent and child divs come our in green, but the child div is supposed to come out in cornflowerblue.

Although it is not affecting me yet (I haven't decided whether to use this particular CSS feature), I was wondering if the issue was known.

so each time i set my network to manual proxy configuration, the browser wont load searches and still can't intercept request on burp suite. i have imported the certificate,and added foxy proxy add-on . Note that i was able to do all of this few months ago and it suddenly stopped working. i was seeing a message that says invalid peer certificate signature
