Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Is there some text-shadow used?

If you are familiar with using the DOM Inspector then you can check the CSS code of the tab text.

hey thanks for the quick reply. here's a screenshot http://www.mediafire.com/view/?c2a2l69ci5zbq#bt6qrwr6ku8m5n6 i think we just have to add some antialiasing in the userchrome.css? but i don't know the code. here's my modified userchrome.css

   /* Inactive Tab */
   tab:not([selected="true"]) {
     color:white !important;}

   /* Tab while loading */
   tab[busy] {
     color: blue !important;}

tab .tab-text {
 font-size: 12px !important;
}

/* tab font */ 
tab .tab-text {
font-family:Verdana !important; 

} 

i read somewhere else the problem is more evident with white text on dark background

thanks
