Great Extension Rated 5 out of 5 stars
This is a great extension in Thunderbird! I use it every day, and was sad to see it not working with updated versions of Thunderbird (versions 7 & 8). Missed the functionality Toolbars provided.
But, I installed "Add-On Compatibility Reporter" extension to Thunderbird and now the Toolbars extension (and a few others) works perfectly. Download that extension to solve your update problems.
