Firefox does not load properly since 11/30/17. Why not??
Firefox does not load properly since 11/30/17. I know it is that date, because I now have a file on my Desktop, "Firefox Old Data". Why did this happen?
My homepage does not load, and my Bookmarks toolbar and add-ons are not available. History is there, and Bookmarks are there, but the page is not as it was. I cannot use Lastpass.
What happened? How can it be resolved? Will it happen again?
My son the computer wizard has tried to figure it out, without success.
I do not know my password, and Firefox was installed long ago on an email address I no longer use or can access, [email protected].
I want my old Firefox homepage back!
Thank you.

Sometimes when there is a problem, Firefox will try a refresh. This creates the "Firefox Old Data" folder with your old FF profile.
Let’s do a full clean re-install;
Download Firefox For All languages And Systems {web link}
Save the file. Then Close Firefox.
Using your file browser, open the Programs Folder on your computer.
Windows: C:\Program Files C:\Program Files (x86)
Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux
If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Do Not remove the profiles folder.
Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.
After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

If you have the "Old Firefox Data" folder on the desktop then the refresh feature in Firefox has been used and a new profile got created.
You can copy files like these with Firefox closed to the current profile folder to recover specific data.
- bookmarks and history: places.sqlite
- bookmark backups: compressed .jsonlz4 backups in the bookmarkbackups folder
- cookies.sqlite for the cookies
- formhistory.sqlite for saved form data
- logins.json and key3.db (decryption key) for Passwords saved in the Password Manager
- cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
- persdict.dat for words you added to the spelling checker dictionary
- permissions.sqlite for Permissions and possibly content-prefs.sqlite for other Site Preferences
- sessionstore.jsonlz4 for open tabs and pinned tabs
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
