It’s All Text! is a Firefox extension that let’s you edit text entries you may need to do in your preferred text editor.

It adds as small transparent button to a corner of text areas which you can press to launch your selected text editor with a uniquely named file IAT! creates.

Save the file and the text entered is loaded from the file into the text area, which is temporarily colored and faded out, providing a nice visual confirmation.

It seems not to work with rich text areas like WordPress post editor. I tried to post this entry on it but it just didn’t seem to be able to synchronize the file. In Gmail compose window the button didn’t; appear, so I guess it’s limited to plain text entries.
