1018973 - PDF's current position is intermittently modified when "Current view" is selected

Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect, P4)

Description

[Petruta Horea [:phorea], Desktop QA]

Reproducible on:
Firefox 30 beta 9 - 20140529161749
 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0
latest Aurora - 20140601004001 
 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0
latest Nightly - 20140601030204
 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0

Steps to reproduce:
1. Open a PDF (eg http://www.pdfill.com/example/pdf_commenting_new.pdf)
2. Scroll down and select the "Current view" button from top bar, right side
3. Pay attention to the url (it is modified with the current view page and zoom details)
4. Press again several times the "Current view" button

Actual results:
When the "Current View" button is clicked, the "zoom" query string parameter's last value is incremented by 1. This happens for 6-7 times and the page view is automatically scrolled down. 
e.g: "zoom=75,-310,351", the last value which is "351" will be incremented by 1 each time the button is selected, becoming "zoom=75,-310,352" and so on. 

Scroll and try again several times if cannot replicate from the first time.

Expected results:
The url and the page view remain the same.

Notes: 1. Also reproduces on Ubuntu 12.10 32-bit, but with a lower frequency. I didn't see it on Mac OSX 10.8.5.
2. Also reproduces on Firefox 19.0.2 so it's not a regression.

Works for me with Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:106.0) Gecko/20100101 Firefox/106.0

Even in Mozregression with Build from 2014-05-29 I was not able to reproduce.

I couldn't reproduce this issue nor the duplicate bug 1018973 using Firefox 105 beta 9 under Win 10 64-bit.
