User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20170521144518 Steps to reproduce: My addon adds a stylesheet to display unloaded tabs as semitransparent. In order to convert it into a WebExtension, I need a way to change the opacity, font color, or another prominent visual feature of unloaded tabs to make it look faded.
The new themeing API allows some of these, see bug 1330328 for more. Applying a general stylesheet for tabs isn't a goal for WebExtensions.

that bug has no information though. where are docs about that theming API? can i modify the look of individual tabs programmatically from my addon? if the answer is “no”, this is not a duplicate.
