1269323 - Browser action's pop-up doesn't resize if document size changes

Status: RESOLVED DUPLICATE of bug 1215025

(WebExtensions :: Untriaged, defect)

Description

[Wladimir Palant]

Attachment: Minimal test extension

Steps to reproduce:

1. Download attached extension.
2. Go to about:config and set xpinstall.signatures.required to false.
3. Open Add-ons Manager and install the extension from file.
4. Click the extension's icon in the toolbar (generic puzzle icon).

Expected results:

The pop-up shows both the text "Some text here" and "Some more text", without having to scroll. That's what you get in Chrome.

Actual results:

Only the text "Some text here" is visible, you have to scroll for more. The second line has been added dynamically and the pop-up size didn't adjust.

Chrome automatically resizes the pop-up whenever the size of the document inside changes, regardless of when it happens. Firefox doesn't seem to implement any mechanism like that, size is only being set when the pop-up loads.
