The SEC_ERROR_BAD_SIGNATURE error in Firefox prevents users from accessing websites on the browser. Since it is a browser-specific error, you might be able to access the website on other browsers. Before proceeding to any solution, it is necessary to verify whether the website is genuine or not by opening on another reliable browser (e.g. Chrome or Edge) and checking it out.SEC_ERROR_BAD_SIGNATURE error in FirefoxIf the website works fine with other browsers, the issue while opening it on Firefox could be caused by interference by an extension or an anti-virus. Other than this, proxy settings on your browser might be preventing you from accessing the website.Clear the cookies and cache files for FirefoxTurn off the Firewall and third-party anti-virus programs temporarilyLaunch Firefox in Safe ModeRemove Proxy settings from your Firefox browserYou can try the following solutions sequentially to resolve the problem:1] Clear the cookies and cache files for FirefoxBefore proceeding to further solutions, you could try clearing cookies and cache files for Firefox.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'thewindowsclub_com-medrectangle-4','ezslot_2',815,'0','0']);__ez_fad_position('div-gpt-ad-thewindowsclub_com-medrectangle-4-0');Click on the Library button and select History from the menu.

Since one of the causes of the issue is troublesome extensions, you could try launching Firefox in Safe Mode to isolate this cause.Open Firefox and click on the Menu button.Select Help > Restart with Add-ons Disabled.This would launch Firefox in Safe Mode. Try opening your website. If it works fine in Safe Mode, you would have to find and delete the troublesome extension.To check the list of extensions, open the address about:addons on the Firefox browser and go to the Extensions tab.

I tried logging into an account yesterday, after typing name and password it showed an error page saying bad signature on certificate. I do not have a screenshot. Error occurred only one time, I think it's a problem on the other end.


Only one thing The unsecured sites (http) will be not affectedBut when you will encounter a website that does not support TLS 1.2 but support TLS 1.0 the browser will shown this error (see screenshot)


No, the site uses https for everything, green lock and all. FWIW, I did receive the same error later in Monday, but it was not after a login but after clicking to check unread messages while I was logged in.


I have logged into that site, has to be a hundred or more times and that was the first time I saw that error ever. I've been on it today and everything is running smoothly. I was just worried my password may have leaked.


The certificate is not related to your password is related to the site owner ability to encrypt the information and assure you (and the browser too :)) that this information can't be viewed be unauthorized person. The certificate is per domain not per page. This error "sec_error_bad_signature" can be related to a self-signed certificate or to an intermediate certificate error.Intermediate certificates sit between an end entity certificate and a root certificates and create an additional layer of security that assure that the root certificate keys are inaccessible.Hope this help even if is a basic explanation.Have a good day.


I just want to confirm, firefox read the bad signature and did not send any information when I got the SEC_ERROR_BAD_SIGNATURE page, correct? If this is the case, you can mark this as solved. Thank you again


I renamed the cert8.db file and restarted FF. I now get the normal "untrusted" error then re-imported the private CA to make the "untrusted" error go away. However, that still gave me SEC_ERROR_BAD_SIGNATURE. So, something must've changed.


I knew it was related to the CA certificate. Sigh. OK, so there were two CA certificates with the same name and I only loaded one. One was SHA-1, the other one was SHA-256. I had the SHA-256 but not the SHA-1. The private URL I was trying to access was made with the SHA-1 and has yet to move over to the new SHA-256. Added the SHA-1 certificate resolved my issue. Mismatched certificate was the reason. I think this error needs to be more specific than just "bad signature". Hope this helps other people!


Deleting the cert8.db file as originally suggested here ended up being a hit-or-miss fix to the problem. For some users it worked swimmingly; others it did nothing at all. In fact, for some users even uninstalling Firefox and nuking their Firefox APPDATA folders, Registry Entries, and etc. did not fix the error.


Antivirus can also cause the Firefox error. If there is the antivirus installed in your computer, you need to check if Firefox is detected as the untruth software by it, if it is, remove Firefox from the list. Or you can disable the internet security option in the antivirus. When the two settings above don't take effect, you can disable the entire antivirus directly to check if the blocked websites are accessible in Firefox again.


The HyperText Transfer Protocol (HTTP) 406 Not Acceptable client error response code indicates that the server cannot produce a response matching the list of acceptable values defined in the request's proactive content negotiation headers, and that the server is unwilling to supply a default representation.


In practice, this error is very rarely used. Instead of responding using this error code, which would be cryptic for the end user and difficult to fix, servers ignore the relevant header and serve an actual page to the user. It is assumed that even if the user won't be completely happy, they will prefer this to an error code.

A 400 Bad Request, also known as a\u00a0400 error\u00a0or\u00a0HTTP error 400, is perceived by the server as a generic client error and it is returned when the server determines the error doesn\u2019t fall in any of the other status code categories.\nThe key concept to understand here is that the 400 Bad Request error is something that has to do with the submitted request from the client\u00a0before\u00a0it is even processed by the server.\nThe Internet Engineering Task Force (IETF) defines the\u00a0400 Bad Request\u00a0as:\nThe 400 (Bad Request) status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).\n"},"name":"What is a 400 Bad Request Error?","@type":"Question"},"acceptedAnswer":"@type":"Answer","text":"There are various root causes that can trigger the 400 Bad Request error and, even if this error isn\u2019t specific to any particular browser or OS (operating system), the fixes do vary slightly.\n\n\nURL String Syntax Error\nCorrupted Browser Cache & Cookies\nDNS Lookup Cache\nFile Size Too Large\nGeneric Server Error\n\n\n","name":"What Causes the HTTP 400 Bad Request Error?","@type":"Question","acceptedAnswer":"@type":"Answer","text":"Complete the steps outlined in this section to help diagnose and correct a 400 Bad Request.\nThe proposed solutions include:\n\n1.
