After last update, many of my attachments have changed to "Firefox" HTML Document

I Keep a "master file" on the desktop of genealogy data, and numerous graphics used in e-mails. It appears that about the time of the last update to Firefox, many of my graphics, and other information have changed from their original designations (e.g. jpeg,, etc.) to FIREFOX. I can open the files by changing to "open with windows viewer", however if I copy it, after opening, it will not paste into my e-mails. They will not even paste into Paint. What in the world could have occurred?? If it is opened without changing it from Firefox, it only shows gibberish. I attempted to add an image, however even when it has been copied to the desktop it will not show up so I can add it to this message. These items in the file show up as Firefox HTML Document.

HAVE NEVER HAD AN EXPERIENCE SUCH AS THIS PREVIOUSLY IN THE MANY, MANY YEARS I'VE USED FIREFOX. The icon showing up is the FF icon on all of these, and not what was there originally. I have been struggling for quite some time attempting to determine what the problem is.

ANY AND ALL RECOMMENDATIONS WILL BE MOST APPRECIATED.

What is the file extension of those files?

This can be a problem if you have changed the default browser to another browser and back to Firefox. In such a case all icons of shortcuts are reset to their defaults.

cor-el: The extensions were originally jpg, gif, etc.

I have been having problems with KEEPING Firefox as my default browser, and this is because I noted that it had changed and was suddenly NOT my default browser. This has been occurring on a continuous basis after one of the last FF updates. Just long enough, apparently to mess up my graphics, and other information which I have kept in my Master Folder. Very disheartening. This occurred every few days, so I continued to keep checking it each time I opened FF, changing it back to my default browser.

Therefore I changed nothing, only noted that many times FF was showing as "not being my default" browser, although it appeared that was, and I do not use the IE although I do have it (for emergencies).

This, apparently is an insurmountable problem, not of my making, and I do not know how to solve it. I will attempt to go to the link you have provided however I may not have time today.

Thank you so very, very much for your recommendation, I will see what I can do.

Last month there had been an abnormal amount of Firefox updates due to security issues that were exposed at pwn2own, so there have been four extra Firefox 36 releases and now two Firefox 37 releases. That six releases in about seven weeks.

cor-el: Thank you for the information on all of the issues referenced in the links you posted.

I did not have the "automatic updates" checked, however very seldom did I see an alert, I have another program that checks for out-dated programs, which is where I noted the updates and immediately applied them. So I am changing this to "auto-update", now as well as checking the "background service" and hoping that will possibly help in protecting the browser in the future. In the past I had selected "notify only".

I do appreciate your guidance. I will update Firefox the ASAP. Thank you once again. I will post here, if there is any change with my current dilemma.

cor-el:

I revisited this problem once again, and I found that if I right click on one of these attachments (which were converted to Firefox) and choose Windows Photo Viewer, it changes those graphics if I designate this as the "default", however it also causes Firefox to show up as NOT being my "Default Browser". 

At least I know that if I want to use these graphics I can convert them when necessary to the Windows Photo Viewer which shows as an HTM file.

I DO want to show Firefox as being the "Default Browser", so it appears that I must just leave these graphics as they are and only convert them to the Win Photo Viewer when I plan to use them.

I did find a link which is over 10 years old about something which appears to be similar. It is:
