Disable Opera Thumbnail Previews on Windows 7 Taskbar

If you are one of the people who does not care for the Taskbar Thumbnail Previews in Windows 7 then we have a quick and easy way for you to turn them off in Opera Browser.


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”.



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.

    I am a great fan of Opera, but the previews in Windows 7 is the most annoying feature. Luckily it can be shut off, plus it’s a bit overkill, since tabs allow for a screenshot of pages anyway.

    Hey, thanks for this.
    I have a question. I see you switched off the menu bar (or whatever it is called, the thing with File, Edit, View etc) but I don’t see close buttons on your tabs. How do you close tabs then? I ask you because I leave many tabs open at once and close buttons just don’t fit on them (besides I find much convenient to have a dedicated space for close button instead of separate buttons for each tab), so I have to switch on menu bar to display normal window buttons (minimize, restore, close). If I could find a different method (with a single mouse click) to close tabs I would switch off menu bar and make document area bigger by that.

    @lori – The close button will appear when you hover your mouse over the right end of the tab…until then it stays hidden. ^__^

    Thanks for this. I had been troubled with this ‘feature’ of Opera for long, but never thought about checking opera:config for disabling it.

    @lori: You can close tabs with the middle click of the mouse.
