How to Disable Aero Glass Transparency in Mozilla Thunderbird Window?

If you are an older user of Mozilla Thunderbird email Desktop client, you might have noticed the addition of Aero Glass interface since 5.0 version of Thunderbird. Thunderbird 5.0 and later versions utilize Aero Glass feature of Windows Vista and 7 and provide transparency behind menubar and toolbar as shown in following screenshot:


At first look, it looks great but people who use dark Desktop backgrounds face problems while reading the text in Thunderbird window and it becomes quite annoying for them.

If you don't like Aero Glass in Thunderbird, you can disable it using this tutorial. We are going to share 2 methods to remove Aero Glass from Mozilla Thunderbird menubar and toolbar:

3. Click on Apply button and launch Thunderbird. Now you'll completely get rid of Aero Glass as shown in following screenshot:
