hello, thanks for reporting that - i have the same rendering issue on the site you've mentioned and have filed bug #903507 for it.

is my problem been resolved?

i'm just a normal user like you and lack the knowledge to fix such an issue - i've just reported it at the right place so that developers can take a look at it. i'm certain that it will take some time until the issue can be fixed, but if you're interested in its progress you can put yourself on the cc list of that bug...

You can use Opera Mini to read Gujarati.

This is a limitation of Android device, not of Firefox. However, there is a solution to this problem if you can use Opera Mini browser.

Start Opera Mini browser and then type config: in the address bar of Opera Mini and scroll down to the last option: Use bitmap fonts for complex scripts. Select Yes from the drop down menu at the right-hand side. Then click on save and restart Opera Mini.
