Sorry for the late reply.
It appears that it is NOT a PDF issue but rather that Firefox is really using up all my CPU.
Here are my steps to test:
- Booted normally.
- Opened system monitor
- Opened FF ONLY...5 tabs total from previous session.
- CPU went to 98.5%
Waited for CPU to lower down which it did now at 31%.
Next test was to boot up and try same steps EXCEPT opened Google Chrome in front of FF. Let my tabs open in Chrome first. All were loaded. CPU usage only went to 60%. Once FF began to load, system monitor hit 100% and froze.
Waited for 3-5 minutes and system never worked. Forced to do hard reboot as I could not use my Force Quit.
Is this a function of the new FF using too much resources? I tend to use 2 browsers at the same time and like FF although if it continues to do this, may move over to Brave as my 2nd browser.
Looking for any advice on this and sorry that it appeared to be a PDF issue. It is definitely NOT that as I can work fine on PDF files on my other computer as well as this one if FF is closed.
