I have upgraded Firefox to 110.0 on MacOS, and now our installation of EE will only load a few pages before every page gets stuck loading and only placeholders are shown. Clearing storage and restarting lets me load 2 or 3 more times, but then back to the same only placeholders. This is not the case in Safari.
Errors in console:
Uncaught (in promise) TypeError: NetworkError when attempting to fetch resource. The resource at “...” preloaded with link preload was not used within a few seconds. Make sure all attributes of the preload tag are set correctly.
Any ideas what may be going on?
