Full uninstall of both the 32 and 64bit with data restore did fix the issue. Please note, following the 'Firefox Reset' and 'Repairs' did not work. There are no issues even when going back to the my notoriously slow, junky websites that used to be plagued with this issue.

I now have been through a couple of Firefox updates and I have now run Firefox 51.0.1 64bit for a long time (weeks) and no glitches.

I then downloaded and fresh install of the FireFox 64Bit, used the MozBackup utility to restore my websites, saved cookies, etc. Nothing fancy, just the default cleanups. LOL I also used the CCleaner and did a regular cleanup and Registry Cleanup. Throw it on a flash drive for fun and extra safety. I uninstalled it all deleting data, settings, etc.ДЇinally after restarting the computer, I did a search (folders showing hidden files and folders) for Firefox and deleted everything it found *except* my MozBackup, backup file! Do not accidently delete your MozBackup data file. I don't remember the questions asked during the uninstall but I think it asked some options for a partial uninstall and a full uninstall.

Then I returned to my Control Panel > 'Programs and Features' to uninstall the 64 bit version.

#Firefox 51.0.1 64bits 32 bit

I uninstalled the 32 bit version in the ProgramsX86 installed folder by this method. I know one of the 'magic gurus' here will know exactly where and what the Firefox uninstaller (32bit) is called, located, etc. I apologize for not having the specifics. Uninstalled Firefox (both versions) I cannot remember ( this has been some weeks back) but I think I had to go into the Programs X86 folder and find the uninstaller. I downloaded (newest version) and used 'Moxbackup' Read Here. BUT here is what I did and the problem has not returned. Thought maybe my Win7 Ultimate 64 was somehow sharing files between them.

I found I had 2 different installs of Firefox! OMG. It has been working reliable since Mid-DecemberВ !!! YaYВ !!! I started using Chrome (yuck) for a while until I finally discovered and fixed the issue. No matter what I tried, I could not get rid of this error.

I do not know how to flag 'Problem Solved' maybe a mod can do this? Then ''uncheck'' the box for 'Enable Adobe Flash protected mode' and try that for a day to see whether it helps.

You can disable it using the Add-ons page. That feature has security benefits, but seems to have serious compatibility issues on some systems. We have a general support article addressing potential solutions to this issue: Warning Unresponsive script - What it means and how to fix it.ДЄnother common cause of unresponsive script errors on Windows 7-10 is the protected mode feature of the Flash player plugin. The goal is to make everything run more smoothly but some kinks are still being worked out.ДЄssuming this is related to a script in the page: e10s separates the browser interface and page content into separate processes. Based on further research, I believe this is a new way of reporting things like unresponsive scripts and plugins when you have the new e10s feature enabled (this was first 'turned on' for some users in Firefox 48, and more users have it turned on in Firefox 49).
