I just downloaded 112.0.2 and it also breaks login.nine.com.au.

A refresh of firefox does not solve the issue.

Appears that 112 has an issue with my profile. I need to completely delete my profile for nine to actually work with 112. With 111 there is no issues with my profile. Rather painful upgrade experience....

This is on a VM with no extensions and no bookmarks....seems no way around the breakage.

New profiles do not correct the problem. This appears to be a more fundamental issue with firefox.

Uninstalling 112, deleting the profile and reinstalling 111 appears that every thing works perfectly. If you then upgrade to 112 and try to keep the old 111 profile (although it is completely empty) results in these web pages no longer functioning. Trying to use the default 112 profile results in the pages not showing login details and a completely blank page. Refreshing firefox does not result in the web pages being displayed. Disabling protection does not assist either. Reinstalling 111 and pointing the profile to the 112 profile on the surface works but you can not actually login to the site and it continuously displays the schedule can not be loaded.

Reverting back to 111 and everything works but I can not see how to get a working profile. However, 112.0.1 and 112.0.2 definitely have a bug.

and trying to take the 112 profile back to 111 breaks 111 as you would guess. Seems there is no way to get firefox to work any longer with nine.com.au. Tried as much as i can with playing with profiles. Short answer is 111 works fine but 112 breaks it. Once updated to 112 appears you are stuck and no way of going backwards other than wait for some one to fix this. In the mean time i guess its is off to edge as a browser.

Better add 7plus.com.au to that list of broken streaming sites as well by the looks. It no longer can get past the first page either. Tried in a blank VM and the same answer. Now this forces me to a different browser. Edge on the same 2 machines works perfectly.

I have solved the immediate issue and found the real culprit. Appears that the manner in which firefox is handling certificates has changed between versions. Accessing these web sites with both versions provides a grey shield in regards to protection. Turning this on or off did not alter the web site appearance. I installed firefox nightly 114a which interestingly gave me a pop up regarding the certificate being untrusted. This appears to have been replaced by my antivirus performing scanning of the https connections and replacing the cert. Temporarily uninstalled my antivirus and the web pages work as expected in 112. I just needed 114a to provide that hint because 111 worked fine. Guess now the question becomes why are these untrusted certs being utilised. Thats another day.......

Anti-virus software usually adds a policy to import root certificates from the Windows certificate store to prevent such certificate issues when they hook into the Firefox internet connection.
