How can I backup Firefox 92.xxx (not by syncing to another computer)

There used to be plugins in much older version of FFox, but those days are gone. I understand that the Sync function allows sharing of login/passwords between several machines, but is there any way to simply backup login/passwords of one computer that does not share anything with any other computer. There does not seem to be any way to do this -searching FFox help yields nothing.

Sometimes, the simple ways work well, and this would be such an occasion. This function ought to be built in to every software program, but unfortunately this does not happen.

Thanks for reading

Back up and restore information in Firefox profiles {web link} I use a Legacy add-on that makes backups of my user profile, Just In Case. Unfortunately, it is not compatible with the current Firefox.

Every now and then, open the profile folder and create a copy of the current profile as is to another location on your hard drive. This way you will have a backup.

If you do this each day, you will not lose much data. This should be done with Firefox Closed.

Note: In case you need to restore from these backups, you may need to overwrite old or corrupted files.

You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
