Back in 2008 we reviewed a Firefox add-on called Text Area Resizer & Mover which did a great job of resizing textareas. Not only the ones that were to small but also the ones that were to big. It was even possible to move the textarea but this often caused problems with the site layout.

Textarea++ is a new experimental add-on for the Firefox web browser that offers a similar functionality except for moving textareas on the screen. It has a few aces up its sleeve though making it interesting enough to justify a review. Textareas can be resized by simply moving the mouse cursor to the lower right corner. The textarea can then be increased or decreased in size. The developer claims that it works with all textareas even those that are loaded dynamically and we have not found a textarea during our tests that would make that claim invalid.

Another interesting option is the addition of a scrollbar for textareas where more text than the visible limit can handle has been entered. This scrollbar is added even if scrollbar functionality has been locked by the webmaster.

Textarea++ is an interesting add-on for users who regularly post on websites that offer an improper textarea for that task. Users who prefer a bookmarklet find the Form Text Resizer bookmarklet at The Man In Blue page. And there are also quite a few userscripts, for example that by Julien Couvreur that provide a similar functionality.

Update: Textarea++ has been discontinued. Firefox users can instead install the Resizable Textarea add-on.
