How-To Enable Aero Peek Preview With Firefox Tabs

Groovy Firefox LogoEver since the introduction of tabbed browsing, there haven’t been very many circumstances where having extra windows open is useful.  This scenario is particularly the case with the impressive new Aero Peek feature built into the Windows 7 Taskbar.  Unfortunately, it wasn’t until Firefox 3.6 that Firefox supported Aero Peek with its browser Tabs. For some reason, Firefox comes with this feature disabled by default???  No worries, I have a simple tweak to enable Aero Peek Preview with Firefox Tabs!

 

How To Enable Aero Peek Preview with Firefox Tabs

 

1. In a Firefox window Type about:config in the address bar.  When the page loads, you’ll see a warning that you are about to enter the advanced settings of Firefox.  Click the I’ll be careful, I promise! button to open advanced settings.

2. In the Filter box Type or Paste in the following:

browser.taskbar.previews.enable

The filter should now display the preference with a matching name.  Once you see it Right-Click it, and then Select toggle.  This action will switch the Value from false to true.  You can also Double Click the setting to set the value as True.

change the browser.taskbar.previews.enable preference

 

The setting should take effect immediately (it did on my system.) However, you might need to restart Firefox for the setting to take effect fully.  Once completed, just hover over the Firefox Icon to see all the Firefox tabs currently open in all your Firefox windows.

You’ll also notice that the Firefox taskbar icon now has tabbed edges, the icon will now change functionally to identify that there are additional tabs open within Firefox windows.

    Hey, thanks for this – very useful. I always hated it not displaying the preview! Nice work.

    Awesome. I agree with Jordan. Firefox never showing up in Aero peek always pissed me off. Now it works!

    Do you have a fix for chrome????

    Darn….doesn’t work for me. Nothing listed under “taskbar” in about:config list. What am I missing???

      Are you running Windows 7? (I’m sure you are but had to ask) Also, did you do a search for everything under browser. ?

      What version of Firefox are you running?

      • Stephen Porter July 4, 2010 at 2:13 pm #

        Yes–Win 7. After my post here I did some more searching discovered that there are other/different steps for setting up Firefox to show tabs with Aero-peek. I changed those and it is working now.

        Thanks for the feedback!

    Came across this post by mistake (wanted to know if its possible to ‘pin’ previews) but this is cool, always used to annoy me how FF did this!
