Firefox initially popped open a window stating that I already had another copy open and so wouldn't open. After some investigating, I found a fix and followed the steps to delete profiles - possibly the cause of the errors. (I had applied this solution once months ago and it had worked then.) Subsequent to this attempt, I was unable to open Firefox - even with the creation of new profile(s). Given the situation, I deleted Firefox entirely by dragging into Trash and emptying the trash and re-logging in. Downloaded a clean new install from the Mozilla website. Although the DMG file downloaded fine, when I attempt to copy app to Applications folder, the system hangs. So now there is no way to re-install Firefox?!
This link /post seems to reflect my condition: https://support.mozilla.org/bm/questions/1240427
However at the given location on my computer, I only had a FB video plugin - even after i deleted that, there is no change, i.e. remain unable to implement a fresh new install of Firefox.
p.s. Using a different computer to post this. When I get a chance, I'll go back to the one with this issue and see if I can post the "troubleshooting information".
