How to Use Greasemonkey in Opera

I’m sure most of you are aware of Greasemonkey, well if you don’t then it’s a Firefox extension that allows Firefox users to install scripts that make quick changes to web pages. Using this extension you can add new functionality to web pages and web sites like adding an HTML signature in Google, bypassing image verification in Orkut, changing an orkut theme or a Gmail theme, etc.
If you’re an Opera user then there’s a good news for you. Opera supports Greasemonkey scripts! These user scripts work exactly how they work in Firefox. You can simply import them into Opera unlike in Firefox you where you need to install the Greasemonkey addon. Here’s an easy tutorial which will guide you to do so:

1. Download the Greasemonkey script you want to use.
2. Now, rename the script so that it ends with “.user.js”

3. Open Opera and go to Tools > Preferences > Advanced > Content and click the JavaScript Options button.

4. In User JavaScript files field, choose the location of your scripts folder and click OK.
5. Restart Opera for the changes to take effect.

    First of all, Opera has had the ability to run user javascript files (userjs) for a long time now.

    Also, not all Greasemonkey scripts are compatible with Opera. Most will work fine, but don’t expect all to work.

    Lastly, a restart is not required to enable this feature. Every time a page is loaded Opera checks for updates to userjs and added/removed files and the scripts will be loaded on the next page load. Just open a tab and go to google or reload your current page. 😀

    Good post!
