Access to older version of Firefox
I have DLink webcams around my home and I can no longer access their web pages to control them because of certificate issues. I have no success with Microsoft Edge running in IE mode either. Using IE mode I am able to get into two of my D-Link Camera’s web pages but with the other two (one of which is my newest camera) I get this message:
The browser you are using may have difficulty receiving images and video. If you experience any issues viewing this page, we suggest using Internet Explorer.
When I go to the MyDlink website using Firefox Version 128.5.2 ESR I get this message:
Unsupported Browser or Operating System Detected! We recommend you use Firefox 12-51/52 ESR on Windows or MacOS to access the mydlink portal.
Is there a way for me to get the Firefox version they recommend?

Since you have Windows 10/11 an easy way to use a old version of Firefox without affecting you current Firefox version install and its Profiles is to use portable Firefox. You should Not share the same Profile between current Firefox version and a rather old version like Firefox 52 ESR.
They use the official Firefox builds paired with a custom launcher that keeps everything self contained so it can run completely off a usb flash drive for example.
Portable Firefox 52.9.0esr is at https://portableapps.com/apps/internet/firefox-portable-legacy-52#localizations and you can run it on your hard drive, SSD or even off a usb flash drive whenever you want to access your old MyDlink cameras.
It's possible that the site specifies using an old version of Firefox (or maybe Internet Explorer 11) because it relies on a proprietary plugin such as the Java Runtime Engine.
I suggest just using Edge for those cameras rather than dealing with old vulnerable software.
Sorry, I misread that. Some cameras do NOT work in Edge, but they have certificate issues in Firefox. Presumably the certificates are self-signed or expired, and no version of Firefox would be happy about that. Assuming the error page has an Advanced button, could you click that to get the technical error code?
