Firefox was slow so it suggested 'renewing' and getting rid of add-ins. What I didn't realise is that is has eliminated my certificate to identify myself to secure government institution websites (in Spain). I am right in the middle of tax returns and I am now totally screwed. Is there some way back?

Isisombululo esikhethiwe

You can copy the cert8.db file and possibly the cert_override.txt file in the "Old Firefox Data" folder on the desktop to the current profile folder to recover (intermediate) certificates.

You can use this button to go to the currently used Firefox profile folder:


When you reset/refresh Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported. The current profile folder will be moved to an "Old Firefox Data" folder on the desktop. Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.

It is possible to recover data from the old profile, but be cautious not to copy corrupted files to avoid carrying over problems.
