Sorry fred, that didn't fix anything. :(

Your System Details shows;

Installed Plug-ins

Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

Flash: Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac

Then reinstall the latest version.

Flash Player Version 17.0.0.188
https://www.adobe.com/products/flashplayer/distribution3.html

Dang it. that one looked promising. didn't notice there was more than one instance of flash installed. I fixed that problem (thanks for noticing, btw) but the problem still occurs on google.

Remove History For One Site Open the History Manager <Control><Shift> H. In the search bar, enter the name of the site. Right click on one of the listings and select Forget About This Site. This should remove all information, including any passwords / settings.

nope, that didn't work either. :(

You can check the Net log and the Network log in the Web Console (Firefox/Tools > Web Developer) to see what content is blocked (file size is zero) or otherwise fails to load.

• https://developer.mozilla.org/Tools/Network_Monitor

If images are missing then check that you do not block images from some domains.

• Tap the Alt key or press F10 to show the Menu Bar

Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"

Check "Tools > Page Info > Media" for blocked images

• Select the first image link and use the cursor Down key to scroll through the list.
• If an image in the list is grayed and "Block Images from..." has a checkmark then remove this checkmark to unblock images from this domain.

Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

The web console gives me this:

In [Console] alot of these: "This site makes use of a SHA-1 Certificate; it's recommended you use certificates with signature algorithms that use hash functions stronger than SHA-1.1 images"

one of these (each): "SyntaxError: unterminated string literal1 rs=ACT90oHrkp0u27-kfObgJBO6Eh037tWJUg:917:24"

"14:30:34.120 Use of getPreventDefault() is deprecated. Use defaultPrevented instead.1 google:63:0"

As for page and default permissions, those check out. Same goes for software and addons. I've tried with these disabled in the past and the error still occurs.

Did you try Safe Mode?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Try to rename (or delete) the permissions.sqlite file in the Firefox profile folder.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• http://kb.mozillazine.org/Profile_folder_-_Firefox

sadly those two have not yielded any results :(

Hmm. WamJam seems to have been the source of the problem. My partner said it was needed to play a flash game yesterday and I found that suspicious. Obviously, that turned out to be the case. Googling it resulted in multiple malware results...

So removed, tripple cleaned, shredded and 3 decades of cleaning later, it works again.

Thanks for the assistance and your patience everyone.
