Turn Off Firefox’s New Mixed Content Blocker
August 23, 2013 3 Comments
With version 23 of the Firefox browser, they’ve implemented a mixed content blocker. This will block content that has been loaded from an non secure source, if you’re viewing a secure page (i.e. https). However, it’s been shipped with a bug in that it if you allow the content to be shown, it only remembers it for that page load.
This turns into a rather tedious repetition of allowing the content. When you’re developing web content in a devel environment, that may include mixed content, it’s rather annoying.
Until that bug is fixed (reportedly in Firefox 24), you can turn it off in Firefox’s advanced config. Please note, that you should only do this if you know what you are doing and that the content you are browsing is indeed safe.
To do this, go to ‘about:config‘. In the search box, type ‘mixed’.
In the options that should appear:
- security.mixed_content.block_active_content
- security.mixed_content.block_display_content
Change block_active_content to false and leave block_display_content as false. This should enable the content without the blocking notification/actual blocking.
thanks for this tip

thanks for the tip. How is the new mixed content configuration saved once I set it to allow for mixed content from a webpage?

I’m not 100% certain, there’s some conjecture that the setting is either session based or permanent (ie registry).
