Site completely broken with CORS rejected issues in firefox? Edited

I'm completely unable to use firefox I get dozens of errors like

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS request did not succeed).


I'm just browsing to the site. Firefox url ->> <site> ->> Does not load ->> console errors

This firefox add-on fixes it:


This is a CORs issue. I believe that Firefox has implemented CORs correctly and atlassian is broke. 


Top notch support btw

BTW, the fact add-on fixes it is a BAD thing.

(Atlassian's top notch support just emailed me that there was a fix to my problem)

lol I just got a badge for first accepted answer.

Hey Andrew - have you entered a support ticket with Atlassian? 

@Andrew MainlandWhat was the fix? I still see the issue with the latest version of firefox.

The "fix" that I put above was only to confirm that this is a problem that atlassian needs to address.

That "fix" works by overriding Firefox's security mechanism (turning off CORS completely) What I think should happen is that the devs at atlassian head over to mozilla's documentation read it and then adjust the headers accordingly.  

Had this been my company I do not imagine the end user would notice this bug for longer than 1 hour max.

I had exactly the same problem - thanks for the solution
