Yes it is.

Do you get any error messages?

The H drive is a partition of my second hard drive (which does not contain my OS or programs), of which H drive was acting as my backup. One day Windows decided that partition needed repaired. Unfortunately, what Windows did not tell they were erasing that drive. Similarly, Windows "repaired" the sister partition (G), only not all the data was erased. That drive is somewhat useable which is why H drive (a partition actually) is still hooked up. I have tried 4 recovery tools. H drive is not readable at all. Of the files not even seeable on G/sister partition, the best I got was all 1s and 0s. This happened over a month ago. Since then I have done two clean installs of Windows 10 and Office 2013 Pro (Microsoft had to install them and could not explain why my installation disks would not work). Everything was working fine until I went to install Firefox Quantum Beta because I got tired of Firefox using 40-50% of my 12 GB of RAM.

Start your Computer in safe mode with network support. Then start the Firefox installed. Is the problem still there?

Windows 10 does not start in safe mode with networking. I tried it again, just to make sure I remembered that correctly and sure enough it disabled my internet connection. However, since I had saved the download to my desktop as had been instructed, I was able to get Firefox to install. Fred McD, thanks for the time taken to help me get Firefox installed. I do have two related questions perhaps you could answer. A. Will I have to go through this when I install Firefox in the future, or are the files now loaded or the correction made so I do not go through this again? B. With nothing done to Firefox 56.0, with only one tab open, Firefox is using 30% + of my 12 GBs of RAM. Isn't this excessive?

Also need to mention that while on the first page displayed, yahoo.com, and before I even got a chance to respond to your latest advice, https://chaejwolfmedia.org, the firefox-patch.js virus, appeared. This was appearing after my clean install (plus Firefox, Office 2013, Malwarebytes, an anti-virus, Epson printer app, and Roxio Creator 2010 installed), just as it has for the last two years, but never immediately after I installed Firefox. I reported this to Firefox over 18 months ago, but they have done nothing to get rid of this virus. Maybe you will have better luck getting them to fix it.

I don't know Win 10. You can ask your question here also;

the firefox-patch.js virus, appeared

That can show up from anywhere

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for a good ad / pop-up blocker.

If you want to make sure your system is clean, Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Again, thank you for your assistance.

I just wanted to clarify one thing in case someone with Mozilla reads this. The firefox-patch.js is not a popup. It literally takes over the tab you are currently on, redirects the the tab to https://chaejwolfmedia.org, and the only way to get rid of it is to go backwards on that tab. Four different malware scanners have been run, and AVG, Bitdefender, and Avast to not pick this up. No need to respond. Issue considered closed.
