When you view Tamil texts created with dasBlog like my blog indic page, you will see the Tamil contents not getting displayed properly in Mozilla or Firefox. It turns out to be a problem in the CSS with the text-align:justify; property. I have described this in my earlier blog post last year.
After I upgraded to latest dasBlog version (1.8.5223.2) I selected “Project 84” as my theme, this problem resurfaced. All it needed was going to /themes/Project84 and editing the style.css file. In the file, you need to delete the above-said property in the #content style.
