Firefox update wiped out my home page setting which was a custom configuration for a site that I can't get back. Why did this happen?

An update to Firefox yesterday, Nov 22, 2016, wiped out my home page setting. The home page was a complex URL with custom settings for a site. Why did this get wiped out in the update and where can I find that setting to restore it? This is unacceptable behavior for an update!

Did your Firefox perform a Refresh during the update? If it did, you should find your old profile (settings) folder on your desktop inside a folder named Old Firefox Data.

If you find that the prefs.js file will have your old home page setting.

Don't double-click a .js file because Windows will execute it as a system script. Instead, right-click > Edit the file to open it in Notepad or right-click > Open With to choose a different text editor. Then look for the line starting with:

user_pref("browser.startup.homepage"

and that should have the setting you need (don't include the starting and ending " when you copy/paste to Firefox's Options page).
