Description

[rayslinky]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140317233501

Steps to reproduce:

1. open a window to youtube.com
2. zoom in (ctrl-+)
3. control click a video to open in a new tab (observe that the new page is also zoomed)
4. drag the new tab out of the first window to make a new window (observe that the page in the new window is still zoomed)
5. in the first window, control click another video to load it in a new tab (observe that it is also zoomed)
6. drag the new tab from the first window to the second window (zoom gets reset in this one tab)
7. if you ctrl-+ and ctrl-- the first window, all youtube tabs are zoomed to the correct zoom in all window

Additional info:
I've noticed this bug in the last few versions of firefox on linux, not sure if it exists previously or elsewhere.

User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:28.0) Gecko/20100101 Firefox/28.0

browser.zoom.siteSpecific is set to the default (true)


Actual results:

Zoom is reset on tab moved between windows


Expected results:

Zoom should stay constant
