Firefox wont let me open hotmail
I have been using firefox for a few months now and have had no problems, but last night it stopped me from accessing hotmail.com. This has never happened before, and is definitely an issue with firefox as I can still access my account through explorer. tried restarting my computer but this achieved nothing. Here is the error code:
An error occurred during a connection to outlook.live.com. Invalid OCSP signing certificate in OCSP response. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT
Help!

Hi !
The problem lies with Microsoft, whose servers (in layman's terms) send an expired assurance that their SSL certificate is still valid.
Unfortunately it turns out that Firefox is the only browser checking for this on each secure https site it is loading.
(whereas other browsers glance over that and only check for :
https://en.wikipedia.org/wiki/Extended_Validation_Certificate).
Disable OCSP (for now) : Type in the address bar about:config (press Enter) (promise to be careful, if asked) Type and look for the preference : security.ssl.enable_ocsp_stapling and set it's value to false
It is best to reset this pref via the right-click context menu to true once you are done with this website.

Thanks for your help. Is it ok for me to leave security.ssl.enable_ocsp_stapling toggled to false? It will be very annoying for me to have to toggle this on and off everytime I want to access my email...

It would be best to toggle this on and on, you will need it set to 'true' on other websites. It's a pain in the toosh,   I know, but with a bit of luck Microfoft will fix this ASAP ......
You can leave it off for the current session if you wish, but then you won't notice that this is fixed by MS.
You can consider to create a user.js file in the profile folder to restore the true setting of the pref, so you would only do this once after a Firefox restart.
The user.js file is processed on every start of Firefox.
user_pref("security.ssl.enable_ocsp_stapling", true);
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
