How to Troubleshoot Missing Certificate While Browsing on Firefox

Firefox Freezes Every Few Seconds

Troubleshoot Firefox Error

Mozilla Firefox verifies the certificates of websites that support secure browsing. If Firefox cannot validate the security certificate of multiple sites, you might run into an error page that denotes the issuer of the certificate is unknown to Firefox. Consequently, your connection to the website is not secure. If the error pops up on multiple legitimate websites that allow financial transactions, refer to the first two steps below. If it is specific to a particular website, read on for troubleshooting steps for SSL errors.

Change Scanning Encrypted Connection Feature in Antivirus Suites

If you come across such errors, it is also likely an antivirus suite’s scanning secured connections feature has replaced the legit site’s certificate with its own. If that is the case, you should disable the antivirus software’s feature from its settings.

Scan for and Remove Existing Malware

Malicious software can not only cause Firefox freezes every few seconds but also the SEC_ERROR_UNKNOWN_ISSUER error. In fact, some malware types intercept secured web traffic on a browser and cause the said error message to appear on multiple sites. To clear the browsing inconvenience, scan for and remove malware on the computer.

Troubleshooting Steps for SSL Error on Specific Sites

Contact the Website Owner if Needed

This step is applicable if the error pops up while browsing on Firefox over a public network. If the description of the error suggests that an intermediate certificate is not found, enter its hostname into an online service that tests SSL web server’s legitimacy. If the third-party SSL testing page returns Chain issues: Incomplete, a legit intermediate certificate is certainly missing. If that is the case, inform the website about the missing certificate. To get the description, click on Advanced button on the web page that states the connection is not secure.

Bypass the Error Page

If the description suggests that the certificate missing issue on a website accessed over a private network is due to the fact that it is self-signed, bypass the error with the below steps. This can be done provided the intranet website allows adding an exception for visiting the site, despite the certificate not trusted by default by Firefox.

  • On the error page, click on the Advanced button and select Add Exception. This will open up a dialog box for adding security exception on Firefox.

Security Exception

  • Click on View to explore the certificate and read its description specific to the site.
  • Confirm Security Exception by clicking on its button if are you are sure to surf the web.

Certificate Confirmation

If you still come across Firefox freezes every few seconds issues or any other SSL errors, contact a browser support team to fix the problem.

How to Troubleshoot Page Cannot Load Error on Internet Explorer

Internet Explorer Not Responding

Common Browser Issues

While surfing the web, people come across the frustrating Internet Explorer not responding error message; the same goes if IE cannot display a web page popups. These two are the most commonly encountered errors in the default browser of Windows. Some of the troubleshooting steps mentioned below are more or less the same as for Internet Explorer not responding issues, which is especially the case with disabling the browser add-ons.

Disable Add-Ons in Internet Explorer

This works if the web page failing to load fully has to do with the add-ons installed in IE browser. To detect that and disable add-ons, follow the below steps.

  • Click on Start, search for Internet Explorer (No Add-ons) in the search box, and open it.
  • Now, try to open the same website you had encountered the error on Internet Explorer. If it is loading up, then an add-on installed in the browser may be to blame.
  • To disable that, go to Internet Explorer standard mode, click on the Tools menu, and navigate to Internet Options.

Disable Add-Ons

  • Under Programs, click on the Manage add-ons option to open up its dialog box.
  • Click on an add-on in the browser from the list that pops up to the right side, and click on Disable

 Manage Add-Ons

  • Repeat disabling add-ons until you figure out which one is causing the browsing inconvenience on Internet Explorer.

If that fails to resolve the “web page cannot be displayed” error, see to it if your internet connection is working fine.

Double-Check Browser and Internet Settings

Check the modem, wireless, router, and other settings to ensure that they are working. If such settings are ok, double-check the PC’s IP address following the below steps.

  • Press and hold down to Ctrl and R keys to open Run dialog box.
  • In Run, key in cmd and press Enter

Internet Settings

  • In the popup window, type in ipconfig and hit the Enter
  • In case you see the IP address column starting with 169.254, it is likely the issue has got to do with internet connection as it’s a private address of Windows. Contact your Internet Service Provider if that is the case.

IP Configuration

If that is not the starting letters of IP address shown, see to it if the browser is configured to Work Offline mode.

  • Click on the File menu in Internet Explorer and check if the said mode is chosen.
  • If so, deselect the offline option.

In case you come across Internet Explorer cannot display the web page error in future, get in touch with browser tech support for a timely response.

How to Troubleshoot Waiting for Proxy on Google Chrome

Chrome Constantly Crashing

Common Browser Issues

Users of Google Chrome often encounter an error message saying, “Waiting for Proxy”, especially while trying to open a website. Much like Chrome constantly crashing, even taking too much time for a web page to load up fully can cause much annoyance to those surfing the web. However, there are several steps to resolve the error on Chrome. Prior to proceeding with the below steps for that, ensure that the website or web page you are trying to open is not appearing fully only in Chrome.

If the website or page loads fully in other browsers, launch the Chrome tab in Incognito mode by pressing and holding down Ctrl, Shift, and N keys. If the website returns with 404 Not Found error message on incognito window, you will have to clear browsing data of Google Chrome. For that, press and hold down Ctrl, Shift, and Delete keys on an active Chrome tab, and choose Clear Data from the window that pops up. Note that this step might also fix Chrome constantly crashing issues.

It is also seen that “Waiting for Proxy” error occurs because of IP preference change from IPv4 to the other configuration. In case your system has configured IPv6 address, it will first try that, even though if it is assigned automatically without a proper gateway. Once this particular connection gets timed out, the system will try to establish the connection with IPv4 instead, and the web page will load without any glitches. So if clearing the browsing data fails to resolve the “Waiting for Proxy” error on Chrome, follow the below steps to fix it.

  • Click on Start button, and search View Network Connections in the search box.
  • In the Control Panel window that pops up, right-click on LAN connection and choose Properties.
  • Assign a default IPv6 connection that is valid or disable it and choose IPv4.

Chrome Not Responding

  • Now open Chrome, click on the menu button to the upper right, and choose Settings. From the new window, select Advanced and click on Open Proxy Settings under the System This will reveal Internet Properties dialog box.
  • In the Connections tab being revealed already, click on LAN settings, deselect Automatically Detect Settings, and click OK.
  • Confirm the action by clicking Apply and OK in the previous window on Google Chrome.

Troubleshooting Tips

 

This should fix the “Waiting for Proxy” error on Chrome. However, if you are still facing the issue, or need help with Chrome constantly crashing problem, get in touch with a browser support technician for advanced troubleshooting.
