Toggle Word Wrap is a Firefox extension, it toggles word wrapping in Thunderbird (Composer window) or Firefox (PRE elements). Toggle word wrapping and PRE element wrapping in the message composition and HTML display windows, respectively.

In the message composition window of Thunderbird or Seamonkey, it comes in convenient when inserting long text lines which should not get wrapped in the final message (such as log file entries, or diffs inserted into the message body). It only has an effect when using plain text mode for composition - this is a per-account setting which must be configured by disabling "Composition & Addressing" "Composition" "Compose messages in HTML format".

Unchecking "Enable Word Wrap" in the Options menu (or pressing the keyboard shortcut) will temporarily turn off word wrapping for the current message - lines will take up the whole width of the composer window, and no line breaks will get added to the outgoing message (with the exception of "hard" line breaks inserted manually).

Checking "Enable Word Wrap" will enable word wrapping again and set it to the standard width (which is modifiable through the "mailnews.wraplength" preference in the Config Editor, the default is 72 characters).

Requirements:
* Firefox
* Thunderbird
