Opera users on Windows 7 may want to disable the thumbnail previews that are displayed on the taskbar. By default, these previews are enabled and can take up a lot of space on the taskbar. To disable them, follow these steps:

  1. Open Opera and go to Preferences.
  2. Under the General tab, click on the Taskbar button.
  3. Under the Show thumbnails for Opera windows checkbox, uncheck it if you want to disable previews on the taskbar. ..

Before

Here is our Opera Browser with four tabs full of HTG Network goodness…

Hovering the mouse over the Taskbar Icon gives a nice preview of each tabs content.

Looking closer you can see the fanned edge on the Taskbar Icon indicating that there are multiple tabs open. This is all good but what if you just want something simpler?

Disabling the Previews

If you want to disable the Taskbar Thumbnail Previews in Opera you will need to type opera:config in the Address Bar and press Enter. Once you have done that, you will see a condensed listing for all of Opera’s preferences. There is one Preference Category that we need to look for…User Prefs.

Note: While a Quick Find Search could be conducted for the entry that needs to be modified, we have chosen to show the full method here.

After scrolling down and finding the User Prefs category you will need to expand the section. Notice the size of the scrollbar in comparison with the screenshot above…there is quite a lot that you can look at and finesse in Opera if desired.

Scroll down until you find the Use Windows 7 Taskbar Thumbnails entry.

Uncheck the box but do not close the opera:config Tab yet…or your changes will not take effect.

Scroll down once more until you reach the end of the User Prefs category and click Save.

With this particular modification you will need to restart Opera after clicking OK.

After restarting Opera the Taskbar Icon and Taskbar Thumbnail Preview will revert to the minimal Windows 7 default as shown here. You can see Opera’s Tab Bar in the thumbnail and the Taskbar Icon no longer has a “fanned edge”.

Conclusion

If you want to disable Opera’s Taskbar Thumbnail Previews on your Windows 7 system, then this quick modification will help get it sorted out in just a few moments.
