Page-viewing problem in Iceweasel on Debian testing/Jessie

[Muntasim-Ul-Haque <nineteen@iut-dhaka.edu>]

Hi,
I just upgraded to Debian testing. Here I'm facing some problems 
regarding Iceweasel. I cannot see writings/fonts in some webpages. For 
example, when I'm writing a blog on Blogger, I cannot see the writings 
but after it's done, I could see it published. Again some webpages are 
creating the same problem. I cannot see web content, like materials or 
writings, but images are clearly visible. So what should I do?
