Any other small issues ? Did you update or a clean install ?
it was an update from 42 to 43 went smoothly but bug related to firejail (firejail firefox) which today chatgpt5 has confirmed has been noted by real world. I post a little more info at MT earlier when I had it up. I can post the the more technical info from fedora:

I find chatGPT is pretty good with linux output, it explains what is wrong with possible fix, but since this bug seems to be widespread on other 43 systems, I'm going to wait it out and see if fedora techies fix it.
