Dear all!

I used to open DB2 in Firefox on macOS.

All of a sudden under macOS my DB2 complains in Firefox.  
However, under macOS the DB2 continues to work nicely in Safari & Chrome.  
Interestingly, on my iPhone DB2 complains in Safari but works in Firefox.  
On Linux (Debian) Firefox works.  
See attached files.

I have no clue why this happens. I did nothing noteworthy … that I remember

Log is rather vage. Reports a broken pipe whenever DB2 reloads.

Old DB1 continues to work where DB2 fails (Firefox on macOS).

Any idea?

Cheers, Uwe

Open the browser developer tools console and see what errors are shown there. I don't know how to do that on a mac, but no doubt your favourite search engine will tell you.

FireFox Browser Console reports `Uncaught TypeError: can't convert null to object`. No clue why it does that and why it didn't before.

And, most important, no clue what to do about ist.

Is there anything before that error?

Also try clearing the browser cache. Use the menus, don't rely on any key shortcuts to do that.

Never had to consider the cache w/ NR before ... Thanks!
