TextareaQualityDeck is a focused Firefox extension for reviewing multi-line text fields. It looks only at <textarea> controls and reports authoring details that affect accessibility, clarity, and editing comfort. Textareas often carry high-value user input: support messages, comments, feedback, profile descriptions, order notes, bug reports, and moderation decisions. Small markup problems can make these controls harder to understand or easier to misuse. This extension checks for labels, placeholder-only prompts, invalid length ranges, tiny row counts, missing sizing hints, disabled required states, and questionable spellcheck settings.
