I need to download a certificate from a device in my networt called secunet Konnektor

https://www.secunet.com/loesungen/einboxkonnektor

on the manual it's written how to do it.

https://www.secunet.com/loesungen/einboxkonnektor#c1607

I suggest to find a manual somewhere in the first link or in google:

chapter 7.4.3

go to chrome (same with edge)

click on the lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

somehow click on the button where you can open a small windows called "certificate".

The "General" tab shows informations about the certificate.

Click on the tab "Details" and click on "Copy file".

The certificate-assitent opens and after clicking on next, you choose DER-coded-binary X.509 (.CER)

Save the file somewhere where you can find it.

I can't do this on firefox

On firefox I can find a lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

when i click on it and then on something else, i can then click on more informations.

a windows opens called "page informations"

under "security" i click on "view certificates" and a new tabs opens called "certificate for konnektor".

but there is no possibilty to download a cer-file. only a pem file and it doesn't really help me.

Error NS_ERROR_NET_INADEQUATE_SECURITY on every page

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

Dear Mozilla Community,

I have problems with one website. This website is poczta.wp.pl. Sometimes this can't be loaded. I see this error:

"SSL_ERROR_INTERNAL_ERROR_ALERT".

This is website with https protocol. What is the reason? Other websites works fine. I think that this is not problem with my router or internet provider because I changed both and it is still problem there. I had this problem also on another computer with Windows 10 operating system. I contacted with administrator of this website and they think that all is okay so they suggested me that this can be problem with browser or my computer.

This behavior is very hard to test because this issue is showed very rare. Sometime one time in one week and sometimes two time in one day. I don't know what is going on with this.

Can you help?

I am unable to connect to the Nord VPN website or the Express VPN website because of a security issue with the Firefox Browser and I am unable to bypass the security and go to the site anyway. Here is what the message said: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nordvpn.com because this website requires a secure connection.

What can you do about it?

www.nordvpn.com 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.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Today is the day I cannot use Firefox anymore. It keeps on blocking webservers in my local network because of a self-signed certificate.

It is a shame, I have been a loyal Firefox user since Netscape. Today marks the beginning of the end of this journey. A pitty.

So, Chrome it is from now on.

Edited to add TLDR: some Firefox requests to Google servers seem to fail internally. What can I try to diagnose the problem?

I'm having a recurring problem with Firefox on various Google sites: google.com, Gmail, Calendar, Keep etc. For long periods of time (but not always), Firefox completely fails to load the site, or loses its connection after the page is loaded (for example Gmail displays an error message "Oops... The system encountered a problem (#001)"). The problem usually seems to occur for periods of many minutes, with occasional gaps where the sites work properly. Also, it seems to be site-specific: sometimes it will load google.com normally while Gmail is still having problems. This is really frustrating, I'd like to use Firefox for all my browsing but I also need to use Google services regularly and that doesn't work if Firefox won't load them properly most of the time.

I'm pretty confident it's a problem with Firefox itself, and not with my network or computer, because I get the same issue across multiple Firefox installations and versions (Firefox 90 and 91 on Windows 10, and Firefox 78.10.0esr and 90 on Linux), and while the problem is happening I can access the same sites successfully from a different browser on the same computer (Chrome or Edge). I've tried refreshing my Firefox profile, working in a private browsing window and using a completely new profile, but the problem still occurs. I've also made sure I'm using "Standard" protection in Firefox's security settings and disabled Enhanced Tracking Protection for the sites I'm trying to access.

I've tried to look at what's going on using Firefox's Network Monitor, and the key thing that seems to happen when this problem occurs is that one or more network requests to a google address (google.com, mail.google.com or ssl.gstatic.com) appear with "0 B" in both the Transferred and Size columns (see screenshot attached). Sometimes the failed network request has a simple padlock icon as in the screenshot, and sometimes a red error symbol with mouseover text that says a security error prevented the resource being loaded. There's also occasionally an error message in the Console: "A ServiceWorker passed a promise to FetchEvent.respondWith() that rejected with 'TypeError: NetworkError when attempting to fetch resource.'.". Removing the relevant service workers in about:serviceworkers doesn't make any difference. On Linux, I've tried using tcpdump to check the actual network traffic and it looks like nothing is actually sent across the network for these requests, so whatever the problem is seems to be happening inside Firefox itself.

Ticking the "Disable Cache" box in the network monitor doesn't help. If I manually resend the same request using the menu in the network monitor, a normal response is received (but the content is not actually displayed in the browser).

It looks to me like some kind of caching or security problem, where Firefox somehow gets in a state where some network requests are blocked or fail to load from a cache, but after a while whatever is causing the problem is cleared and it works normally for a minute or two before the problem recurs. I would simply report this as a bug on Bugzilla, but I can't offer steps for anyone else to reproduce the problem because it only happens when I'm logged into my own Google account. I've run out of ideas for how to diagnose or fix this. Can someone suggest anything else I should try? Thanks!

I tried several things to try and isolate this issue, but all to no avail. The file does exist, and loads in the previous version of Firefox.

Any help would be greatly appreciate.

Hello,

After upgrading to Firefox 91 when I visit site with self-signed certificate in Private window I always get Warning: Potential Security Risk Ahead error even though the certificate had already been added to exception list while not in private browsing. It looks like in private window certificate exception store is not honored. There was no such an issue before version 91. This behavior is by design or it could be a bug ?

I'm wondering if it is possible that Firefox will cease providing a button to proceed to MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT site? My question arises from the following experience.

I connected to a website and the Firefox browser didn't recognize the certificate that the website provided. The following message then popped up: " Potential Security Risk Ahead. " and the user was provided a button to "Accept the Risk and Continue", adding this unsafe website into the exception site list. I think that this is quite insecure. Is it possible that in the future Firefox won't support the button to "Accept the Risk and Continue" to unsafe websites and cease supporting the exception site list to the user?

Hi,

There are circumstances where the domain owner of a given site could indeed have misconfigured their web site and I am grateful for Firefox detecting this and not immediately loading the page. My concern however is that I don't have the freedom to continue no matter what I try ("Advanced" only provides with the error message and has "Go back" option). I had to go so far to install Chrome in order to load the page - it detected the same problem but had a "go to the page despite this error" possibility. I am grateful for the security protection of Firefox but I would appreciate being allowed the freedom to load a page after being warned of any potential security hazard rather than being forced to not open it.

Thanks,

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.
