I need that function that like click on the extension icon with the mouse wheel, it turns on/off "Activate for this site".

And for the "list of ignored websites" to synchronize between Linux and Windows, because it doesn't exist now.
---
Oh, and also "disable on known dark mode sites", which adds automatic detection of dark mode in as many sites as possible, and in a new tab with an open image/video/sound.
---
Detection of `#firefox-screenshots-preselection-iframe` element on the page.
This element appears on the page when I use "Take Screenshot", Firefox's built-in page screenshot tool.
Once detected, firelux2 should automatically temporarily disable on this page to prevent the screen from changing colors.
Sometimes I forget to turn off firelux2 before taking a screenshot, and then I have to take it again...
This should be an option, because maybe someone wants the colors on the screenshot to be changed?

Is there a chance for this?
