Hi ByGhost,

Thank you for your add-on.

I am giving you 3 stars because:

1) I did a test at (https://www.bennish.net/mixed-content.html), and your add-on enables more stuff than "security.mixed_content.upgrade_display_content = true" (it is expected both to have the same result). By the way, please, what exactly is the difference between your add-on and "security.mixed_content.upgrade_display_content = true"?

2) When mixed content is upgraded trough your add-on, there is no visible icon/signal informing that. The content upgrading seems to be automatic. It will be nice an icon/signal, allowing users to chose between upgrading or not.

I will raise my rating to 5 stars, and I will edit my review, if you, please, answer my 2 questions.

Thank you once again.

I suggest adding Save and Reset buttons into setting page, then users will be allowed to save settings or to resolve wrong settings.
