Comment # 30 on bug 1212101 from Christopher Yeleighton

Work-around:

1. Install MozillaFirefox, MozillaFirefox-translations-common of 20230610!
2. Tell Firefox to make a new profile!
3. Tell Firefox to quit!
4. Copy the following files to the new profile! places.sqlite key4.db
logins.json permissions.sqlite content-prefs.sqlite search.json.mozlz4
persdict.dat formhistory.sqlite cookies.sqlite cert9.db handlers.json

This will probably make your new old Firefox more or less usable.
