What's new in 4.4
Sources you can read to the last line, a better pretty-printer and a quieter console.
- Sources: scrolling a pretty-printed file reaches the end, on desktop and phones (tested up to 500,000 lines). Toggling Pretty-print keeps your position and does not re-download.
- New token-based pretty-printer for JavaScript and CSS: never changes the meaning of the code (same syntax tree on 3,000 real libraries), no doubled lines on already formatted code, formats inline
<script>/<style>in HTML. - Chrome-style AI "Explain": no more icon on every error. Desktop: it appears after the message when you hover the row. Phones: rows use the full width; tap an error to get an "Explain this error" button.
- Console ⚙ → AI assistance: Explain on errors Compact / Always visible / Hidden, or hide all AI. Choices are remembered.
- Tests on real Firefox, desktop and phone: 4.4 suite 40/40, Sources scroll to the last line, pretty-printer 3,000 libraries + 14 edge cases; 4.3 48/48, resizable pane 22/22, 4.2.1 privacy 23/23, 4.2 74/74. addons-linter 0/0/0.
