how do i stop thai language appearing ?

You will probably have to visit each site to see if there is a link to an international page that allows to choose the language. There are many sites nowadays that check your IP and automatically redirect you to a page in the local language based upon the location of your IP. Such a choice is usually saved in a cookie, so you need to make an allow exception for each of such sites to keep that cookie or you will have to repeat those steps. ---- Other things that need attention.<br> See http://www.mozilla.com/plugincheck/ Your above posted system details show outdated plugin(s) with known security and stability risks that you should update. # Shockwave Flash 10.0 r32 # Next Generation Java Plug-in 1.6.0_21 for Mozilla browsers Update the [[Managing the Flash plugin|Flash]] plugin to the latest version. *http://www.adobe.com/software/flash/about/ Update the [[Java]] plugin to the latest version. *http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform: Download JRE)
