Now you can visit GFY or any one of your favorite VBulletin message boards, go to the forum of your choice (listing topics) and press the "Sidebar Thread List" button in the sub menu.
Your Firefox sidebar will automatically pop open and list all of the threads for you without any graphics or other distractions.
The thread list will auto reload at regular intervals no matter what page you're browsing... even if it's CNN.com, your thread list will always show you what's current.
You can set the regular intervals yourself as well in the extension's preferences. Choices are :
30 sec
45 sec
1 min
2 min
As a side note, there's also an easier way to get to the extension preferences now, just go to your Tools menu and choose "VBulletin Management..."
For those of you who do not yet have the Firefox extension, grab it here:
