Good day,
Our clients are getting errors while trying to submit files on pages using the Ajax Uploader Control (Version 4.1.60623.0) in Firefox 22. All other browsers and Firefox 21 are working fine. The error is easy to reproduce in Firefox 22.
Error : A script on this page may be busy, or it may have stopped responding.
You can stop the script now, or you can continue to see if the script
will complete.
According to a bug open on Firefox Bugzilla #887857, they disabled support for the .size attribute. Quoting a firefox developer :
"Indeed, I removed the support for the size attribute in <input type='file'> but I also allowed styling the <input type='file'> so using the same code path for everyone (ie. using CSS width) should work."
Thanks
