Greasemonkey in Opera

Did you know that you can easily load Greasemonkey scripts into Opera? While Firefox users need an extension for that Opera users can simply import them into Opera. Well, some manual work is required but nothing to serious. Takes probably half a minute to import it.

First you need to download the Greasemonkey script that you would like to use in Opera. You may need to rename that script so that the file ends with user.js if that is not already the case.
Now open Opera and go to Tools > Preferences > Advanced > Content and click on the JavaScript Options button.

There is a form at the end called User Javascript Files that points to the directory that contains all the custom Javascript files. If you got more than one put them all in that directory. I suggest you create a new folder in the Opera directory and name it Javascripts or something like that.

Opera needs to be restarted so that the scripts can be loaded once the folder has been selected. After that it's just a matter of testing the scripts on whatever website they are working on.

    Fantastic! Thanks for the tip. This will put me even closer to a full conversion from Firefox to Opera.

    This is the one of the great things about Opera; the native support for user javascript and css, so no need of Greasemonkey or Stylish.

    The correct way to make the scripts work is to go to the script page and go to the script that you want, press in the Install button \and copy everything in the Notepad and save it like this "namethatyouwant.user.js" without the quotes and make the dir. To me the scripts work fine i used the You tube Enhancer and works really good.

    It's nice that there's a way to make scripts work in opera, but when you want ~30 scripts, this is not practical. Why doesn't opera make an easy way to run them like Firefox, Flock, and Chome did?
