How to overcome right click block in some websites using opera.

       Some websites use a JavaScript toblock the right mouse button and thus the context menu. While 

earlier versions of Opera had ignored such instructions, the current browser runs the JavaScript. Can this 

behavior be changed without deactivatingJavaScript completely?Answer is yes

1. The options for JavaScripts canbe specified in detail in the new version.
2. If you do not want to allow any change in the context menu, you can ban it.
3. For that, click the new Opera button and open ‘Settings | Preferences’.
4. Then switch to the ‘Advanced’ tab and select the ‘Content’ category to the left.
5. Keep the ‘Activate JavaScript’ option activated and click ‘JavaScript options’ next to it.
6. Deactivate the ‘Allow scripts to detect context menu events’ checkbox.
7. Confirm the open dialog box with ‘OK’.

However, a few websites use scripts in order to offer more options in the context menu. You can ban JavaScript  actions dedicatedly only for certain websites so that you do not have to give up this option.

1.  For that, click the Operabutton and open ‘Settings | Preferences | Manage Site Preferences’.
2.  Click ‘Add’ and switch to the ‘Scripting’ tab.
3. You can now deactivate the ‘Allow scripts to detect context menu events’ option individually for this site.
4.  Confirm again by clicking ‘OK’.
