I am using a MaskedEditExtender within my custom control. whenever I try to paste some data into the textbox, especially in firefox. A popup alert prompts me to enter "Your browser security settings don't permit the automatic execution of paste operations. Please use the keyboard shortcut Ctrl+V instead.".

I want to avoid this popup alert. Please provide your suggestions to avoid this popup as this creates a bad impression to the end user.

This type of popup is not coming in any other browser.

Use keyboard shortcuts if the buttons on the web page or other methods aren't working.

  • Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
  • Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
  • Cut: Ctrl+X or Shift+Delete (Mac: Command + X)
