Why are mozilla.com and mozilla.org blocked in the first place by Kaspersky, along with skype.com, dropbox.com, and update.microsoft.com?

more options

I have read the support page about these types of error messages (SEC_ERROR_UNKNOWN_ISSUER), and seen the two suggestions. I tried to update Kaspersky's certificate and I rebooted my computer, but that didn't work so the only other option is to tell Kaspersky to stop encrypting. But I really don't want to risk my security in doing that and I would like to get the value out of what I paid for when purchasing an antivirus like this. Plus, only a few websites like the ones I listed above are blocked by Kaspersky and Mozilla is included. So I would just like to know what is the reason for your website in specific being blocked and if it would be possible for you to do anything on your end to prevent future headaches on the part of Mozilla users. Because at the moment, I can't install any extensions onto Firefox and I can onto Chrome. That doesn't quite make sense to me.

Attached: Screenshots of list of inaccessible encrypted websites and of mozilla add-ons page ( https://addons.mozilla.org/en-US/firefox/search?q=tab%20for%20a%20cause&platform=WINNT&appver=59.0.2 ) that can not be exempted.

See this article about Kaspersky.

If you have a problem with Kaspersky settings then best is to contact Kaspersky for support.

As I said in my initial complaint, I have already seen this page. I tried the 2nd option (I "click[ed] on Advanced Settings in order to try to trigger a reinstallation of Kaspersky's certificate. In the dialog that opens [I clicked] on Install certificate… and follow[ed] the on-screen instructions. [I do not] use a 2015 version of Kaspersky [...] Finally, [I] reboot[ed] [my] system for the changes to take effect.") Unfortunately, the changes did not take effect. And in addition, I didn't want to do the 1st option ( In the Encrypted connections scanning section [to] check the Do not scan encrypted connections option and [to] confirm this change. ") because this would limit the functionality of my antivirus and potentially put me at risk. I hope you understand my concerns and frustrations, however rest assured that I have already contacted Kaspersky about this and mozilla is not the only website affected (see attached list) Thank you

On the error page in Firefox, could you click the Advanced button, then click the SEC_ERROR_UNKNOWN_ISSUER code to see whether Firefox shows the encoded version of the certificate it cannot verify (large block of gibberish)? If so, please copy/paste that encoded certificate into a reply for analysis. Thanks.

Sorry, meant to attach a screenshot of that in the initial post. This is the text of gibberish: https://addons.mozilla.org/en-US/firefox/search?q=adblock&platform=WINNT&appver=59.0.2

Here are some screenshots (1st is the page from which I navigated to the blocked website, 2nd is the page with no "add exception"):

more options

(It would appear as though I clicked copy to keyboard one too many times. Oops. Apologies.)

more options

I don't recognize this certificate issuer:

ContentWatch Certificate Authority ContentWatch, Inc. www.contentwatch.com

They seem to make a product called ContentProtect. Does that ring a bell??

more options

I'm sorry, but I don't understand where you saw "ContentWatch Certificate Authority ContentWatch, Inc." in the certificate I sent; could you please tell me where you saw that company name? In any case, unless they are affiliated with Kaspersky or Mozilla I don't know where it could have come from (I hope I don't have a virus...)

Also, on the Kaspersky support forum, it was suggested that I disable "Inject script into web traffic to interact with web pages" (see screenshot of Network settings page in Kaspersky program); I tried that and it told me "I was at risk" (without a valid explanation of why) but the add-ons search page still didn't work afterwards. I might try completely stopping Kaspersky from scanning encrypted connections, but I thought of Kaspersky Protection, an extension that was automatically installed onto my Chrome a few months ago and was installed onto Firefox as soon as I downloaded that. I have had problems with that extension blocking websites like Khan Academy and Tab for a Cause before (at least I think, because when I disabled it and started using another adblocker the problem went away after a few days), so maybe this is the cause as well? I don't know, I have never gotten a clear answer from any of the support pages I have contacted, but the Kaspersky support forum has definitely been the most confusing so I suspect the problem is with the antivirus.

Fingers crossed, and thank you @jscher2000 for your help so far.

more options

Well I tried the "last resort" stopping Kaspersky from scanning encrypted connections, the original solution I didn't want to do for security reasons, and the page was still unreachable because I couldn't exempt it. So then I tried disabling the Kaspersky Protection add-on; it STILL DOES NOT WORK. I will wait and see for a few days whether the problem fixes itself like it did before on Chrome after I deactivated Kaspersky Protection; in the meantime I will not use Firefox because I'm afraid I don't have enough protection.

Once again, thanks for your help, I'm honestly at a loss right now for what to do to solve the problem, nevermind understanding what the heck is going on.

more options

Please re-enable Kaspersky.

When I submitted the first block of gibberish to a decoder (https://certlogik.com/decoder/) it identified ContentWatch as the issuer of the website's certificate. That is not the real issuer of the genuine certificate!

In my earlier search, I missed something that might be relevant. They also publish Net Nanny. Do you use that or other filtering products on your computer, or on your router, or provided by your internet service provider?

more options

AHA! Yes, we installed Net Nanny a few months ago on this computer. That MUST be it! Ok, so now the question is how to stop it; I know that sometimes the program blocks websites with "violence" or "weapons", and a page pops up informing the user of such. Here, there is no pop-up, so I think it's just the program automatically checking, not blocking. Do you think it's Firefox or Kaspersky that is conflicting with Net Nanny? Or is Net Nanny doing something weird?

more options

(I re-enabled Kaspersky injecting script and scanning encrypted connections, but for now I will wait on Kaspersky Protection and not use Firefox without an adblocker)

more options

You may need to set up Firefox to trust fake site certificates Net Nanny signs. I'm going to link to a different thread for another program, but the principle is the same: https://support.mozilla.org/questions/1206606#answer-1081584
