In India We need to file our Tax return in xml format on-line on www.incometaxindiaefiling.gov.in by attaching our digital signature certificate. Till now we were using chrome but from 1st September chrome has stopped support for NPAPI plugins so we shifted to Mozilla another great browser. In Mozilla everything everything runs fine including JAVA but when we select our XML file and Digital signature and upload the same there come the error "cannot read the file for signing" error. We have found solution to this problem for Internet Explorer by following procedure In Internet Explorer-> Tools ->Internet Option ->Security -> Custom Level-> you should enable "Include local directory Path when uploading file to the server". Create a folder in the "C" Drive called “fakepath” (c:\fakepath) and copy the xml files to this folder. Restart the Browser and you will be able to upload the file there is no option in the Mozillla to include the complete path of the file to be uploaded. But we are unable to upload in Mozilla . we need help Urgently.
