To enhance the security for users on upcoming Firefox 23 version Mozilla has tuned on a preference-security.mixed_content.block_active_content- as a result of this mixed content will be blocked by default.
In the past, we’ve already covered that Mozilla has offered two preferences for Firefox 18. By turning these preference on users able to block insecure content from loading on HTTPS or SSL connected sites. These preferences are: security.mixed_content.block_active_content and security.mixed_content.block_display_content. Now Mozilla has set the first preference value to “true” for Firefox 23 nightly.
Mozilla has enabled the preference to block Mixed Content by default in Firefox 23.
Mozilla has already taken a privacy measure in Firefox 22 to block third-party cookies by default that means users won’t be tracked with those cookies for not visited sites. Now a security preference has been enabled in Firefox 23. We need to appreciate Mozilla here for taking all necessary actions to protect our privacy and in increasing security for us.
Here is what site compatibility for Firefox 23 page says “Firefox 18 introduced preferences to block loading contents from non-SSL (http) sites on SSL (https) pages. One of those preferences, security.mixed_content.block_active_content is now enabled by default in order to enhance user security. That means insecure scripts, stylesheets, plug-in contents, inline frames, Web fonts and WebSockets are blocked on secure pages, and a notification is displayed instead.”
You can see the above said preference being set to True in Firefox 23 Nightly build. Do you like this addition of security to Firefox? share your thoughts with us in comments.
