Modififcations to pages on load as with the old Opera
How can I make modifications to pages on load automatically as this was possible with the old opera.
Is this still possible and how? (yes I know something can be done by extensions, but not everything as it seems)
I would like to set some input values on page load for a query. The underlying HTML is basically this with some js to activate/execute:
<button id="Btn" class="...." title=".....">
<option value="1" selected="selected">AAAA</option>
I would like to set option 3 as the default and exeuted the standard js.
Thanks for any help/suggestions.
