Status: RESOLVED DUPLICATE of bug 786674

(Firefox :: PDF Viewer, defect, P3)

Description

[Andrei Vaida [:avaida]]

Reproducible on:
* 31.8 ESR Build 1 (20150624141335)
* 39.0 RC Build 4 (20150624153222)
* Aurora 40.0a2 (2015-06-24)
* Nightly 41.0a1 (2015-06-24)

Affected platforms:
* Windows 8.1 (x64)

Steps to reproduce:
1. Launch Firefox and open a random pdf file, e.g. http://cp.literature.agilent.com/litweb/pdf/5989-8139EN.pdf
2. Click menu > select the [+] or [-] buttons from the zoom controls available in the panel.

Expected result:
The controls from the PDF Viewer are _not_ affected by zoom.

Actual result:
Zooming in or out is also affecting the controls from pdf.js.

Additional notes:
* This is _not_ a recent regression, as I've managed to track it back to Firefox 30.0 (20140605174243) so far. I'll follow up with a detailed regression range as soon as possible.
