How to Fix Your Firefox Connection Is Not Secure

Here we can see, “How to Fix Your Firefox Connection Is Not Secure”

Mozilla is a fan of secure websites. Websites that begin with https:// have paid for a certificate and are notably encrypted to keep you safe. Firefox considers websites that do not have encryption hazardous, and you will receive this warning.

It can be aggravating to be unable to access your favourite websites when browsing. They’re usually caused by a website that isn’t configured correctly, but you can double-check your date and time and clear your Firefox history to ensure it’s not on your end.

This article will walk you through the fundamental settings to guarantee that your machine or Firefox doesn’t cause these security problems. We’ll look into it:

  • Date and time on the computer
  • Cache and cookies in Firefox


1. Double-check the date and time.

Our web browsers and PCs employ security certificates to ensure that a website is secure. Certain web pages may display security warnings if the date and time are incorrect, and protect programmes such as work VPNs, banking apps, and most social media apps will not function. You don’t need to check the time on iOS (iPhones and iPads) or Android smartphones because they set it automatically.

If you notice that your Date and Time keeps becoming unsynced, you should speak to the manufacturer about replacing your CMOS battery.

On a Mac, how do you check the date and time?

  1. In the top-right corner of your screen, select the time display.
  2. Check that the date and time are both correct.
  3. Select the time display in the top-right corner of your screen, then Open Date & Time Preferences if the time is incorrect.
  4. To make adjustments, click the lock in the bottom-left corner.
  5. Select Unlock after entering your username and password.
  6. Allowing your Mac to set the time is, in most circumstances, the best option. Make sure the box for Set date and time is automatically checked and that a time server close to you is selected.
  7. You can manually set the time if you choose. Remove the check from the equation. Automatically set the date and time, then enter the correct date and time. When you’re finished, click Save.
  8. Select Time Zone, choose your nearest region on the map and refine it by selecting the city you’re in or the city closest to you from the list below.

In Windows, how can I check the date and time?

  1. Examine the time and date shown in the system tray. This is usually seen in the screen’s bottom right corner.
  2. It can be problematic if the date or time is incorrect. To correct:

    • Make sure the Time zone is set to your preferred time zone.

4. You can manually set the Date and Time if you want.
