User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0
Build ID: 20120724191344

Steps to reproduce:

Opened PDF document, tried to zoom in with Ctrl + mouse scroll


Actual results:

PDF viewer control toolbar zooms in together with the document itself.
When resetting zoom in toolbar to fid width, 100%, whatever toolbar stays oversized


Expected results:

PDF viewer logic needs to be worked on. IMHO user should be able to control zoom with toolbar only.

Also, Ctrl-0 resets to default ONLY document, toolbar stays oversized and controllable only with Ctrl + mouse wheel.

Fixed in FF16 by bug 773422:

> #1807 Dismiss native browser zoom, and use PDF.JS zoom instead

I've verified zooming using mouse control on Firefox 30 Beta 9 (BuildID: 20140529161749), latest Firefox 31 Aurora (BuildID: 20140601004001), and latest Firefox 32 Nightly (BuildID: 20140528030219). Zooming now works fine.

There is a remaining issue on Mac OS, where Ctrl + mouse scroll works fine (zooms the PDF), but Cmd + mouse scroll zooms both the document and the toolbar. Bug 1018932 was added separately.
