If you like Thunderbird but feel it needs a little more like a calendar then Lightning is a necessity. Lightning adds calendar functions without need to install a calendar app on your computer. You can even add events to Lightning making it the perfect Calendar add-on for Firefox The only issues with Lightning is the fact Lightning can cause Thunderbird to open slower, It can cause Thunderbird to crash and the file size is pretty large for an add-on. I myself prefer using Thunderbird's Lightning over all other calendar options because it does as much as the others but doesn't need to be installed on your computer.
Pros: Adds Calendar Functions To Thunderbird Customizable Events Free
Cons: Can Cause Thunderbird To Open Slower Can Cause Thunderbird To Crash Large File Size For An Add-on
