1472162 - Make it possible to inspect a "paused" page

Status: RESOLVED DUPLICATE of bug 962491

(DevTools :: Inspector, enhancement)

Description

[Julien Wajsberg [:julienw]]

Nowadays websites are very dynamic by nature: elements appear and disappear on click or on hover, or even depending on some external event.

It would be very useful to be able to inspect a snapshot of a page.

For a concrete example, on slack it's difficult to inspect the action bar that appears at the right when hovering a message.

Would you consider bug 1036722 to be a duplicate of this? This is by far the most thinking we've done over the past few years in this area I think. I've not seen any other proposed solutions so far.
It is different from the snapshot idea, which is why I'm hesitating to close it as a duplicate. I can see the snapshot idea as being useful too, maybe for different reasons.
There's also bug 962491 which might be even closer.
In any case, this is a commonly requested feature and I would love to eventually be able to provide a user-friendly solution to it.

Yeah I think this is closer to bug 962491, especially when I read bug 962491 comment 9. Maybe instead of the debugger's "super pause" we could simply have a "disable JS in this page" shortcut.

Anyway I'm fine duplicating to bug 962491 if you want.
