Download Firefox on top of itself?

I deleted by mistake some certifications of thought of Firefox that would improve the speed. I would like to download and install a copy of the Firefox update. Can I install it on himself, or should I uninstall Firefox first? I have a large number of parameters, I would like to preserve.

Do you mean (root) certificates that you see in the certificate on the authorities tab Manager?

  • Tools > Options > advanced > certificates: display certificates

You cannot permanently delete root certificates.
Only the bits of the trust are reset and you should find them on a next time you start Firefox.
Other exceptions are found in the servers tab.

You can delete the file cert8.db and possible cert_override.txt file in the Firefox profile folder to reset all certificates.

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