Some great Thunderbird add-ons you may like to know about
If you’d like a keyboard shortcut to access instantly your inbox (or any email folder), you can have this and more options by using the QuickFolders (Folder Tabs) Add-On. With this you can cut through the clutter of the folders sidebar and have your most important folders as tabs. Open folders and sub folders, move/copy mails without scrolling around or searching.
EditHtml will let you edit the html code of your email messages. The panel with HTML code is integrated in the compose window; by default it is on the right, but you can have it also at the bottom.
Signature Switch offers removal (or re-insertion) of your signature with just a click. You may not want specific recipients to see your signature; this extension makes it easy to remove it. Moreover you can define different signatures (e.g. for private- or business-use) and easily select them via a toolbar-button. You can also have automatic switching based on recipients.
URL Link allows you to select textual links/URLs in web pages or edit boxes, and follow them as if they were real links. It will always let you follow ‘links’ and also analyses mailto: links.
