First, I use the word "complicated" because I think it is the first web site I visit that requires Flash, but I have not been able to prove that. I know it is not all web sites or simple web sites. I didn't want to offer bias in the question by claiming it is Flash, but that is my instinct.
Anyway, I have been working on this for about a month or so, The behavior is as follows. After a Windows reboot, I start Firefox, and after visiting a few websites, it freezes my entire system; no mouse, not ctrl+alt+del, nothing. Completely locked up. After about a minute or two, it unlocks, and I can use Firefox fine until after the next system reboot. Once I know a website is "complicated", ie, causes this problem, it will _always_ cause it if it is the first visited of the complicated class. However, after the initial freeze, I can visit any website, "complicated" or not, including the original one, fine.
So, say site A and site B cause this problem, but site C does not. I can visit site C and ones like it all I want, as soon as I hit A or B the first time, it freezes as above, then I can hit A B or C in any order all day fine after it unfreezes. Once I reboot, I am back to the same situation. It is 100% reproducible in this way.
What I have done/ what I have --
1) I have no extensions and I use the default theme 2) I have tried turning off graphics acceleration as suggested in another article 3) I have upgraded FF and Flash; FF version does not seem to matter 4) I have disabled every single plugin I have. I do note that the length of the freeze is much shorter when all plugins are disabled
None of the above have fixed the problem.
This started happening after I did a Windows update on Apr 7, 2016. I do Windows updates manually, but it is beyond my pay grade to uninstall each Window's update to attempt to find a causal relationship. It may be coincidence,
As I said, I suspect the problem sites require Flash, but I can't prove that. However, it is still a problem when Flash is disabled, as I said.
I run Windows 7 SP1 Home Premium fully updated, Malwarebytes premium AV, and FF 43.0.1. Since I have verified it is independent of FF version since at least 35, I have not checked for updates.
TIA for any help.
