@colore <blockquote>can you make this trigger when I visit this webpage automaticaly?</blockquote> That was why I used the <tt>if()</tt> statement. I don't know anything about Opera User Scripts other than what I read at the Opera support page that I linked to. I have no idea how an Opera User Script is activated. I suspect you also have to use <tt>document.addEventListener('DOMContentLoaded'</tt>... like you mentioned above. There are many things I don't know about Opera since I haven't used it for years, but they do list all supported JavaScript and DOM methods somewhere on their site. There are many sites that have JavaScript tutorials, but I've found most of them teach bad code (IE JScript and outdated code), or hard to navigate or too many ads/cookies/popups.

It's just that Opera is a good browser and if people want to use it and Opera wants to (try) to support Greasemonkey scripts, then I'm willing to try and make them compatible - if it's just a matter of using a simple <tt>if()</tt> statement to prevent the script from totally failing in Opera then I don't have a problem with that. However I'd rather not have to worry about browser compatibility, and I've no interest in learning Opera DOM. If you get my drift... <p>@colore <blockquote>can you make this trigger when I visit this webpage automaticaly?</blockquote> <br />That was why I used the <tt>if()</tt> statement.
