body: <p>I have  HTML file. I tried the code on Safari and it was working fine. But when I tried this on Firefox, it’s not working.Can anyone suggest how to make it working on firefox?</p>
  
  <p>On click on undo button I want to retrieve contents from the jsp file. Thats working when I used this code on safari on my mac.. but when I open the same file using firefox its not working. I am not sure is it due to browser settings or due to some other reason. I checked browser setting of firefox 3.6.12 installed on mac also it is enabled for javascript and java...</p>
  
  <p>When I checked on HTTPfox it showed in Error loading content (NS_ERROR_DOCUMENT_NOT_CACHED) in the contents</p>
