Switching off OCSP in Firefox

Recently we came across this issue https://discussions.apple.com/thread/3384801 of Captive Portal Hijacking not working in Firefox 7.0.1 on both Windows and Mac, and on the Mac using OS X 10.7.2 Safari and Keychain Access would both hang.

I quickly made these instructions on how to (temporarily) disable OCSP in Firefox. Please note that this lowers the security of Firefox so do this at your own risk.

1. Visit the about:config URL in Firefox

2. Click the I’ll be careful, I promise button.

This might void your warranty warning





3. Search for OSCP in the Filter search field

Searching for OCSP





4. Double click anywhere on that line and change the 1 to a 0. Then click OK or press Return.


Change value to zero

  1. Doesn’t help. I got it disabled, but I still see OCSP error message.
