Hi bncthay, can you copy/paste the message you're getting into a reply?

In case Firefox is having trouble making a secure connection to the site, these articles might help with the troubleshooting:

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

This is the message that I receive. This is the only website that has this issue on Mozilla. No similar problem on mobile devices or Google Chrome

That message (Access Denied with a Reference number) is characteristic of a web application firewall blocking a range of IP addresses to thwart some kind of attack (such as a denial of service attack). Usually it lasts no more than a couple of hours.

This denial has been occurring for 2 days. Hopefully it will resolve itself.

"Forget about this site" suggestion does not work

Such a message can get triggered by an usual request.

Are you using a bookmark or are you entering the website via it main page? Try the latter if you currently use a link to a specific page. Content blocking extensions might also be causing this.

Does not work via bookmark or entering website address manually . This ONLY happens on Mozilla/Firefox. Connection (via bookmark) works on Google Chrome. Problem developed for no apparent reason . This is not a malicious website..it is the National Weather Service

more options

You can check the connection settings.

  • Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

I have used Firefox for several years as my preferred browser and this problem with the www.weather.gov developed only 3 days ago. It is the ONLY website issue so I do not want to change proxy settings and potentially cause other problems. Therefore I will look at the website(which I typically view more than once daily) on Google Chrome and/or my mobile devices.

As posted earlier here is the message I have been receiving:
