tabs.captureVisibleTab/captureTab could support extra options: scrollX, scrollY, height, width, which would be equivalent to the ctx.drawWindow options.

Hi Tim, this has been added to the January 16, 2018 WebExtensions APIs triage meeting. Would you be able to join us? 

Here’s a quick overview of what to expect at the triage: 

* We normally spend 5 minutes per bug
* The more information in the bug, the better
* The goal of the triage is to give a general thumbs up or thumbs down on a proposal; we won't be going deep into implementation details

What are you wanting to use this for and do you think all of these options would be needed?

I'm not sure how useful specifying a scroll offset would be if you don't know what the contents of the page would be. Would just specifying a height be enough?

I want the unscrolled 2 first pixel rows, not the 2 first pixel rows of the visible area. This is what the scroll parameter would let me do.

This would provide a great webpage-browserchrome integration for vivaldifox.

Would be nice to have!

Would like to know what's the state of this...

Is it blocked?

It is not blocked, but it is marked P5 which means it is not a priority for any Mozilla employee, but we would accept patches.
