Looking back at a possible cause. 1 or2 x's a script error would appear but I hit continue I'm sure. When the problem arose the screen was showing my yahoo email account. When I ret'd 3 or so hrs. later, I had a clear foggy screen on my pc with a thin border on the edge. Surprise I could barely make out what some of my desktop icons are. After rebooting twice, I shut down the pc completely for periods of 2 minutes. At which time on start the firefox screen would hold for about 8-10seconds than back to foggy clear.

hello oldeberwyn, from another user we found out that this might be related to malware active on your pc. please close all firefox windows and try running firefox in safemode (by pressing the shift key while you're starting it). in firefox safemode go to firefox > addons > extensions and remove the entry named "Codec v1.0" or any other addons that look suspicious & you have not installed intentionally. afterwards see if you can run firefox normally again...

please also do an in-depth scan of your system with the security software already in place and/or a different tool like the free version of malwarebytes & keep firefox and your plugins up-to-date in order to stay safe on the web.
