8 years ago @SebastianZ Do you know a way one could debug this, eg see the CSS in devtools? I'd gladly fiddle with the styles and propose something myself, alas I'm not familiar enough with the extension to know how it works and how to debug.

8 years ago Add-ons can normally be debugged using the Browser Toolbox. Though the layers can't be inspected using it, AFAIK.

I also just filed issues for it so far, but you can set up a developer environment for Pixel Perfect as described here:
https://github.com/firebug/pixel-perfect/wiki/Developer-Guide
Then you can tweak the CSS located here:

@ZER0: how should I proceed here?
The related anonymous content CSS is here: https://github.com/firebug/pixel-perfect/blob/master/chrome/skin/classic/shared/ua.css#L23
The goal is to display an image (in anonymous content) that scrolls together with the content.

8 years ago Workaround: Using scroll events and manually calculate the position .

Starting from Firefox 44.0 (tested in FF 44.0b2) the layer position is fixed again instead of being absolute. This was initially reported in issue #18.
