Textarea Cache is a handy Firefox extension that automatically saves the text you type into textarea fields on websites, including forum messages, emails, user reviews etc. If the tab is closed unexpectedly (or by accident), you can easily salvage your input from the Textarea Cache log viewer. If there are sites that you don't want to keep in the cache, you can exclude them in the settings dialog. The program only caches the textarea fields, which are usually those for long text input, it does not cache regular input fields designed for Name, Address etc.
