I had a kernal panic this morning after I updated Firefox to 184.108.40.206, and when I restarted I noticed that I got the folder with exclamation point for about 1 second, and then I got the Apple logo and everything booted fine. I haven't noticed any actual problems, but I still find it odd to get that kind of behavior at start-up. Have other folks noticed the same thing? Thanks in advance. BTW, this is after I installed a new HDD and cloned my old 10.5.2 set-up to a new drive.
