Firefox Extension Guru’s Blog

Thunderbird like Firefox does have about:config settings. But, how the heck do you get to about:config in Thunderbird since there is no address bar to type about:config in. The access to about:config is well hidden: From Tools, select Options…, Click the Advance Tab, select (if it is not already) the General sub-tab and finally click the Config Editor… button. Note: On TBird 3 builds you will get a “This gun is loaded!” warning message the first time (and each time if you don’t disable) you access this option.

Alternatively, if you don’t want to go hunting through the Options menu, you can get and setup the AboutConfig extension:

1. From Thunderbird Add-ons >> AboutConfig
2. RIGHT-CLICK on the green install now button and select ‘Save Link As…’ . Note: XPI installs do not work yet in TBird, left clicking the button will install the add-on in Firefox.
3. Save the file (aboutconfig-0.6-tb.xpi) to your desktop
4. In Thunderbird, go to the Tools Menu and select Add-ons
5. Drag the file (aboutconfig-0.6-tb.xpi) from the desktop to the Thunderbird Add-ons window
6. When the Install button becomes active click.
7. Click Restart Thunderbird
8. Right-click in an empty area on the toolbar and select Customize…
9. In the Customize Toolbar window, look for about:config button (likely will be at bottom of list) and drag it on to the toolbar where you want it.
10. Click OK when done. Note: Do not click the X as this will not save your changes.

The newest Thunderbird 3.0a1pre nightly (062707) now has tabs support. It doesn’t work very well, but it is important to keep in mind TBird 3.0 is still in very early development (not even an official Alpha release yet). A couple minor quirks, the close tab buttons are there but don’t do anything (need to right click on the tab and select “Close Tab’). Also double-clicking a message will cause it to open in a new window. You will need to right-click on the message and select ‘Open Message In New Tab’ option.

TBird 3 is also very unstable as it only took a couple minutes of me playing around with it to get it to crash. Also looks like there are issues with Talk Back (which I thought was replaced by Airbag/Break Pad) as I was getting the familiar memory writing error when I exited the application. I’ll be sticking with my 2.0.0.5pre build for a while still but wanted to try this out.

Edit: Added a couple screenshots. Also noticed all the tabs will sometimes reset to whatever folder you are currently navigating in.
