Can I update ALL certificates?

Recently I am forced to run an old version 22.0 of Firefox on my Fedora 17 Linux computer. I now see "The connection was reset" whenever I access https://signin.ebay.co.uk

Although I do NOT see any problem doing the same with a more recent version 38.1.0 running under CentOS on a different machine.

I am forced to use the old version because a manual install of the latest version 39.0 crashes, see https://support.mozilla.org/en-US/search/advanced?a=1&asked_by=bradcan&w=2

I suspect that the problem is perhaps certificate related, although I see NO security alert.

Is there a way to force an update of all root certificates either manually or under the old version?

Is there perhaps another explanation?

TIA Charles Bradshaw

I'm replying to my own question because the issue is simple, for Firefox 22.0 SSL is broken for connections to many https sites with out of date certificates. But 32.0.3 works fine.

Please note 39.0 does NOT even load!

Some explanation would be helpfull.

Try to rename the cert8.db file (cert8.db.old) and delete the cert_override.txt file in the Firefox profile folder to remove intermediate certificates and exceptions that Firefox has stored.

If that has helped to solve the problem then you can remove the renamed cert8.db.old file. Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previously stored intermediate certificates. Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.

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