Firefox is not allowing me to upload files to our internal sites on https

At least since last 3 months as far as I can remember, file uploads to our internal sites which use https are not working on firefox browser. I thought it is really a certificate issue or something else. But I tried uploading the same file to same site on IE and it worked. For example, we have our internal wiki site. I could browse and edit pages and do all other things on firefox. But when it comes to uploading a file, after clicking on 'upload' button, firefox returns an error which includes error code "SEC_ERROR_OCSP_OLD_RESPONSE". On other site which is our internal bugzilla, upload didn't work but this time there was no error code as far as I can remember. It is similar message on the lines of 'Your connection is not secure'. Then I tried uploading the file on IE and it worked. Sometimes, retrying it 2 or 3 times works. On one day I saw after retrying 3 times by clicking 'RETRY' button after the error message, file actually got uploaded twice to the wiki. Today after sometime, I tried uploading the same file to bugzilla(by going back to upload page by clicking on <- back arrow) and it worked this time. There is some problem for sure.

This usually indicates a problem with OCSP stapling where the server sends an expired (cached) OCSP response.

You can try to disable OCSP Stapling temporarily by toggling this pref to false on the about:config page to see if that has effect.

  • security.ssl.enable_ocsp_stapling = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

It is best to reset this pref via the right-click context menu to true once you are done with accessing an affected website since this is a security feature.

Note that this should be fixed on affected server(s) and you can contact your IT department to look into this. Some months ago there had been a similar issue on Microsoft Outlook internet servers that took quite some effort for Microsoft to repair all their servers.
