Every document like the below one does not display in firefox esr 115:

https://support.hpe.com/hpesc/public/docDisplay?docId=c01081836&docLocale=en_US

I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

I require some add-ons for accessibility, which you abruptly disabled today due to "could not be verified". Also, all my other add-ons were disabled for the same reason - see attached. I read "https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist", which doesn't answer my questions. If you can't explain specifically why you did this, or tell me how to override your blocks, I'll uninstall Firefox from all my platforms!
