Hi all,

I have v 5.0.52 in PortableApps.

Even though I am not versed in Certificates, I understand my company installed its own certificate.
E.g., in Chrome when I am at .zotero.org/ and I go to menu -> More tools -> Developer tools -> Security tab -> Overview I see
Certificate - valid and trusted
"The connection to this site is using a valid, trusted server certificate issued by _the name of my company_ WebGateway CA."
https://www.zotero.org/support/kb/site_certificate_info
https://www.zotero.org/support/kb/ssl_certificate_error

I find a few issues, I think all of them a consequence of the certificate issue:
1. In both Chrome and Firefox connectors I have the well documented issue of not retrieving the author names.
E.g., https://forums.zotero.org/discussion/73315/error-when-saving-papers-from-sciencedirect
2. If I try to update Zotero I get "Update XML file malformed (200)".
E.g., https://forums.zotero.org/discussion/66024/cant-sync-probs-w-certificates-xml-files-etc
3. I cannot sync

To deal with issue #1, I tried updating Zotero as a first step; possibly not a solution, and perhaps not even needed, see
https://forums.zotero.org/discussion/comment/315329/#Comment_315329 . At any rate, it would be useful to be able to update.
Then I got issue #2.

So I tried overriding the certificate as shown here https://www.zotero.org/support/kb/cert_override .
I also checked

But the problem is my cert8.db under C:\Users\user1\AppData\Roaming\Zotero\Zotero\Profiles\_randomstring_.default\ is locked for editing/removing as I have my Zotero session open. And as soon as I exit Zotero, the whole directory C:\Users\user1\AppData\Roaming\Zotero disappears (I guess this only happens with the portable version).

What should I do to override the certificate?
