can someone please tell me why firefox is trying to install this unwanted file.....i run bitedefender everyday and everyday this pops up it is ANNOYING Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to sync.contextualadv.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk. Add to exceptions

please email [edited email from public community support forum] ......

Hi,

I believe it's not something Firefox does by default, and this behavior is rather caused by an add-on or a website.

To check if it's caused by an add-on, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.

To make sure it's not a website causing this, go to Firefox Settings -> Privacy & Security -> (scroll down to) Permissions and click "Settings..." next to Notifications. Look for any suspicious websites in the list that have "Allow" next to them and either select Block or remove them from the list. You can even remove all the allowed websites from the list, as you'll be able to give this permission to them later.

Does any of that help?
