"Certificate error - navigation blocked"

I have trouble understanding what a browser is.

The browser is the software you use to access the internet.
Example: Internet Explorer or Mozilla Firefox.

In fact, the basic role of the browser (correct me if I'm wrong) is to transform lines of HTML code into web pages (with colors and other elements).

Hello, I have the same issue as you describe above... I can't connect to the internet, whether with Firefox, Internet Explorer, and I even downloaded Google Chrome and it still doesn't work... and even when I force it, it blocks me... it says invalid certificate or data breach... also, when I click on the Firefox icon, it tells me it's already running... if you can help me, that would be very kind....
Best regards, Virginie

Hello, every time I go to a page, it shows me a security certificate error. I would like to know why this happens?

Hello, you just need to set the date simply.

Yes, it is free.

Don't forget to mark your post as resolved.

You go to parameters, you see browser settings, so you can change it because there are several browsers listed.

Hello,

If you are a user of the KASPERSKY antivirus, try disabling it and then opening a GOOGLE page.
After that, you can reactivate it.

This is the solution that worked for me.

The HTTPS analyses of antivirus programs cause problems when the certificate is no longer present, it is often on Firefox, as the latter has its own store...
Google Chrome and IE use the Windows store.

And how did you solve the problem?

that is to say, Zoha, what do they tell you? Please elaborate a bit more.

Did you receive a code? If not, you cannot open your account like I did when I created a new account.
