¡ Hello Nic ! I hope I can help you, I recommend you to explain a little better your problem but as you have two assumptions I will give you two answers with their solution!
1 | In case your problem is with installing Firefox on your device.
Starting with Mac:
You can download and install Firefox on macOS 10.12 and above. Before downloading Firefox, you can check the system requirements.
# Visit theFirefox download page on any browser (e.g. Safari). It will automatically detect your device platform and language and recommend the best version of Firefox for you.
- Click { Download }
Note: If you want to select a different language for your Firefox installation, click the Download options and other languages link instead.
- After completing the download, the file (Firefox.dmg) may open a Finder window containing the Firefox application. Drag the Firefox icon to the Applications folder.
Note: If you don't see this window, open the Firefox.dmg file you downloaded.
On windows:
Before installing Firefox, see the Firefox System Requirements to make sure that your computer has the required operating system and recommended hardware.
To install Firefox on your computer ( Windows ) :
- Visit this Firefox download page in any browser, such as Microsoft Edge.
- Click the Download Now button. The Firefox Installer that downloads will automatically offer you the best available version of Firefox for your computer.
- Click Open file in the Downloads notification on Microsoft Edge to start the process.
2 | In case your question is about security certificates.
When you visit a website whose web address starts with https, your communication with the site is encrypted to help ensure your privacy. Before starting the encrypted communication, the website will present Firefox with a certificate to identify itself.
An https website is only secure to the extent that the website is operated by someone in contact with the person who registered the domain name, and the communication between you and the website is encrypted to prevent eavesdropping. No other surety is implied.
When you visit a secure website, Firefox will validate the website’s certificate by checking that the certificate that signed it is valid, and checking that the certificate that signed the parent certificate is valid and so forth up to a root certificate that is known to be valid. This chain of certificates is called the certificate hierarchy.
Problems with certificates
When you browse to a website whose web address starts with https and there is a problem with the secure website certificate, you will see an error page. Some common certificate errors are described in the What do the security warning codes mean? article.
To view the problematic certificate, follow these steps:
On the Warning: Potential Security Risk Ahead page, click Advanced. (On other error pages, click More Information.)
Technical details about the error display.
Beneath the Error code, click View Certificate.
The Certificate Viewer dialog displays.
Reporting certificate errors
Certificate error pages include an option to report the error to Mozilla. Sharing the address and site identification (the secure website certificate) for the site that was untrusted will help Mozilla identify and block malicious sites to keep you better protected.
I hope I have helped you, see you!

No problems here with that website. Are you possibly using a VPN or proxy to connect ? You can check the 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":
- Settings -> General -> Network: Connection -> Settings
You would normally expect a DigiCert certificate.
Are you using a proxy or VPN?
You can check the connection settings.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can do a malware scan just to be sure.
