Grab Text Hook Application C 2

Hello! Thanks for you time.
I have:
Win 32 native application that can logging all text which drawing on the screen from most application for e.g. notepad, word, IE. Application start Hook dll (SetWindowsHook api) and hook ExtTextOut and TextOut api functions for logging text. I have use EasyHook native dll for replace (ExtTextOut and TextOut functions). All grab text I store to global memory and then store to disk as text file.

I need:
Text logging which drawing in Google Chrom and Mozilla Firefox when the web page is downloaded. I do not need grab text from network traffic. I need grab text which IS DRAWIND in Google Chrom and Mozilla Firefox browsers.

System Requirements:
Visual studio 2008 c++ native project EXE and DLL and all sources of this projects;
x86 and x64 platforms code compiling;
use EasyHook native dll for this;

Main problems:
Functions that may draw text in chrom and firefox may not be exported from some dlls;
crom can have 2 processes for one page, so need inject dll in second process buy hook createprocess function (for this purpose easyhook has some help functions);

thanks
Alex
