web page does not display anything but text
On some websites, the page displayed is only text (looks like a site outline) which are imbedded webpages. No icons, pictures,etc. t does not happen with IE. It does not happen with most websites. I'd include screen-shots, but this is happening on my wife's Windows 7 machine; I've used a Mac for decades. My knowledge and her machine don't match very well.

Please also ask your wife if she has encountered any "untrusted connection" errors and used the feature to create an "exception." That can cause sites to appear completely unstylized if they retrieve content from other untrusted servers. Any issues like that?
When you get this connection errors for pretty much all secure sites, the problem usually is one of the following:
(1) Error in your system's date, time, or time zone, which throws off certificate validity checks. Sometimes allowing computers to use an internet-based time source can introduce this problem.
(2) Firefox not being set up to work with your security software that intercepts and filters secure connections. Products with this feature include Avast, BitDefender, Bullguard, ESET, and Kaspersky; AVG LinkScanner / SurfShield can cause this error on search sites.
(3) On Windows 10, Firefox not being set up to work with the parental control software Microsoft Family Safety. (To test by turning it off, see: http://windows.microsoft.com/en-us/wi.../turn-off-microsoft-family-settings)
(4) Malware on your system intercepting secure connections.
If you have any of those specific security products:
That would be the first thing to check. This support article will walk you through it: How to troubleshoot security error codes on secure websites.
If none of those ring a bell:
You could inspect a sample certificate to see whether that points to the culprit. If you want to try that now, here's how I suggest starting:

You likely will get an error page. Expand the "Advanced" button and look for an Add Exception button.
Note: You don't need to complete the process of adding an exception -- I suggest not adding one until we know this isn't a malware issue -- but you can use the dialog to view the information that makes Firefox suspicious.
Click Add Exception, and the certificate exception dialog should open.
Click the View button. If View is not enabled, try the Get Certificate button first.
This should pop up the Certificate Viewer. Look at the "Issued by" section, and on the Details tab, the Certificate Hierarchy. What do you see there? I have attached a screen shot for comparison.

Can you attach the screenshots?
- http://en.wikipedia.org/wiki/Screenshot

- Use a compressed image type like PNG or JPG to save the screenshot
- Make sure that you do not exceed the maximum size of 1 MB
Firefox 42+ has a Tracking Protection feature that is enabled by default in Private Browsing mode. When you are in private browsing mode then Firefox can show a shield icon at the left end of the location/address bar that some content is affected.
You can disable this feature in "Options/Preferences > Privacy" (about:preferences#privacy) or via the about:privatebrowsing page that get when you open a New Private Window.
- Preferences > Privacy: "Use Tracking Protection in Private Windows"

If images are missing then check that you do not block images from some domains. You can 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 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.
Check permissions.default.image on the about:config page to make sure it is default (1).
If you use extensions (3-bar Menu button/Tools > Add-ons > Extensions) that can interfere with loading content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions do not interfere with loading content. There is security software that can interfere with loading content, so check that as well.

I've been getting a bit of this lately(W10;FX44.0.2), probably due to various blocking extensions. A re-load of the site always fixes it in a second or two.
