Firefox 3.6 Beta 3 Released…Without Windows 7 Aero Peek?Written by John Thompson on November 19, 2009 · Filed under How To, Software
Remember how excited I got about the beta 1 of Mozilla Firefox 3.6 the other week? Well I’ve just got the latest beta of 3.6, beta 3, and it’s missing a key feature I found in the previous beta! In case you didn’t catch the article, earlier Firefox 3.6 beta’s utilised Windows 7’s Aero Peek feature in the same way as Internet Explorer by displaying each of the tabs in previews.
I also noted that there was a bug, which displayed a spinning circle in the first preview window. This bug was also present in the second beta and apparently the recently released third, which explains its omission from the default features. Despite this, you’ll still find many under the hood upgrades as expected.
If you still have a yearning for Aero Peek in Firefox, however, it can still be done!
How To Use Windows 7 Aero Peek With Firefox 3.6 Beta 3
To do this you’re going to need to access the configuration screen for Firefox by typing “about:config” in the address bar. After assuring Firefox you’ll be careful (“I promise!”) you’re presented with a lot of options and values. You’re looking for a line called “browser.taskbar.previews.enable”, which by default has the value “false”.
To re-enable the feature, this value needs to be changed to ‘true’ by right clicking the line and selecting ‘Toggle’ to change the value. To save time, you don’t have to look for the preference through the huge list, just type a keyword such as “Taskbar” in the filter and the list is narrowed down to 3 choices. Exit out of the configuration settings and you’ll have your previews back! Enjoy Firefox 3.6!
