ฟอรั่มสนับสนุนของ Firefox

I just updated the Firefox browser and installed it successfully. When I tried to open the browser, I got a msg stating that the security of the page I am trying to open has not been verfied. Really don't understand that since it is the firefox browser and this came from Mozilla. How do I correct that?

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

I would be so grateful if anyone has a solution!
