i not sure if problem related telerik control, or firefox problem. seems me more latter.

this problem weird. has been several weeks , still not able solve it.

we have fixed problem. problem still firefox's bug, indicated in post

http://www.telerik.com/support/code-library/preview-image-before-it-have-been-uploaded-with-radasyncupload

the trick part how fix bug: delay 10 ms before calling showthumbnail(...). notice cannot put delay inside showthumbnail(...), doesn't work.

window.currentfileuploaded = function (radasyncupload, args) {     ...     if (navigator.useragent.indexof("firefox") != -1) // if firefox, delay 10 ms. fix firefox bug!!!      {         settimeout(function () { showthumbnail(...); }, 10);     }     else     {         showthumbnail(...);      }  }
