User Agent: Mozilla/5.0 (Windows NT 6.1; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)
Build ID: 20140212131424

Steps to reproduce:

When using the New Google spreadsheets I noticed that the text displayed in the cells has no anti-aliasing resulting in a very unappealing/old style looking text.
This behavior is only with the New Google spreadsheets (introduced a few months ago), the old ones are displayed correctly.
I could reproduce this on my Firefox and also on a new freshly installed Firefox (no extensions, no add-ons).
The text rendering is briefly correct in Firefox while the page is loading/reloading.
I could not reproduce it in Google Chrome or Internet Explorer.

Steps to reproduce:
1. Create new spreadsheet in Google Drive
2. Insert random text in spreadsheet cells
3. Click on the bottom-right "Try the new Google Sheets"


Actual results:

see "Incorrect text rendering" part of image (page loaded)


Expected results:

see "Correct text rendering" part of image (captured while page was loading)
